"I spent decades removing these one at a time. Patients kept coming back with new ones. SK Renewal 40 changed my approach. The 40 percent urea softens compacted keratin from within. I've watched patients go from dozens of rough spots to noticeably smoother skin in two to three months. This is now my first recommendation."

"I spent over $2,000 on cryotherapy in two years. They froze them off. They came back. New ones showed up right next to them. I felt like I was throwing money at something that never ended. A friend told me about SK Renewal 40. I didn't believe a cream could do anything my dermatologist couldn't. But after 8 weeks the bumps on my chest were flatter. Smoother. I wore a tank top to my daughter's soccer game last month. First time in four years I didn't grab a cardigan on the way out the door."
-
"I found a new one every few weeks. Neck, chest, back. I stopped counting after 40. My doctor said they're harmless. That didn't stop me from hating how they felt every time I touched my skin. I started using SK Renewal 40 every night. After about 6 weeks the rough ones on my neck softened. By month three I ran my hand across my chest and actually felt smooth skin. I cried in the bathroom. My husband asked what was wrong. Nothing was wrong. Something was finally right."
How do I use SK Renewal 40?
How do I use SK Renewal 40?
Start With One Spot
Pick one small spot and apply a thin layer. Give it a little time to see how your skin responds. A gentle tingling or warm sensation means the formula is actively working — this is completely normal and fades within minutes. Once you're happy with how it feels, go ahead and treat all your other spots.
Daily Routine
- Wash the area and pat dry
- Dab a small amount directly on each spot
-Thin layer for flat, mild spots
-Generous layer for thick, raised spots - Gently rub in until absorbed — no need to rinse
- Start with once daily for the first week, then twice daily as your skin gets comfortable
Quick Tips For Best Results
- Treat all your spots in one session — neck, chest, back, arms, legs, hands, elbows, knees
- Apply on the spot itself, not the skin around it — this keeps surrounding skin comfortable
- For body use only — do not apply on face, eyelids, lips, or any area above the jawline
- Avoid applying on cuts, open wounds, or freshly shaved areas
- If you're out in the sun, apply sunscreen over treated areas
- Keep away from eyes, — rinse with water if accidental contact occurs
- Store in a cool, dry place away from children
When To Pause
Most people feel nothing more than a mild tingle. On the rare occasion you experience persistent discomfort, blistering, or rash spreading beyond the treated spot, simply pause for a few days and resume with a thinner application.
If you have a pre-existing skin condition like eczema or psoriasis, or you're unsure whether your spots are seborrheic keratosis, a quick check with your dermatologist before starting will give you peace of mind.
Your Journey
- Week 1–2: Spots start softening — you'll feel the texture changing
- Week 2–4: Visible flattening — spots become smoother and less noticeable
- Week 4+: Continued improvement — keep going, consistency is everything
Every skin is different. Some respond faster, some take a little longer. Trust the process and stay consistent.
Tip: Always start with once daily. Your skin needs time to adjust to 40% urea. Jumping straight to twice a day may cause unnecessary irritation. Let your skin get comfortable first. Once it tolerates the formula without any tingling or sensitivity, then move to twice daily for faster results.
Our Guarantee
Our Guarantee
We offer a full 90-day money back guarantee. We give you 90 days because this formula needs time to work. It's softening compacted keratin from within, not burning it off the surface. That takes weeks, not days.
Most people feel a difference in the first 2 to 4 weeks. By week 8 to 12, the rough texture is noticeably smoother and raised areas are visibly flatter.
We chose 90 days because that gives you the full timeline to see real results. Not rushed. Not pressured. If you use it consistently and don't see a difference, contact us and we'll refund you in full.
Will the spots come back after I stop using it?
Will the spots come back after I stop using it?
SK Renewal 40 softens and flattens existing rough, raised areas. It does not prevent your skin from producing new ones.
Seborrheic keratoses are a natural part of skin aging and may continue to appear over time. Many customers continue using the formula a few times a week as maintenance to keep treated areas smooth and manage any new spots early.

Seborrheic Keratoses
Rough, raised growths that feel stuck to your skin and keep showing up on your neck, chest, back, and arms. They started with one or two. Now there are dozens. They catch on your clothing, they itch, and no cream you've tried has ever made a difference.
Keratosis Pilaris
Tiny rough bumps scattered across the backs of your arms, thighs, or cheeks. You've been told it's just dry skin. You've exfoliated, moisturized, and scrubbed. The bumps are still there. They make your skin feel like sandpaper no matter what you put on them
Rough, Thickened Skin
Dry, cracked, hardened patches on your heels, elbows, or knees that build up no matter how much lotion you use. The skin feels thick and rigid. It cracks. It flakes. Regular moisturizers sit on the surface and disappear within an hour. Nothing gets through.
Why 40% Urea Works Differently
Your skin growths are made of compacted keratin, packed in dense, rigid layers held together by hydrogen bonds. Regular moisturizers sit on the surface. Glycolic acid polishes the outside. Neither one can reach the structure underneath.
At 40% concentration, urea crosses the keratolytic threshold. It penetrates into the compacted keratin and disrupts the hydrogen bonds from within. The dense layers that felt hard, raised, and stuck to your skin begin to loosen and soften.
2% Salicylic Acid Finishes The Job
Softened keratin still needs to go somewhere. That's where salicylic acid comes in. It dissolves the intercellular glue holding those loosened cells to each other.
Once that bond breaks, your body sheds the softened material naturally. No burning. No freezing. No scabbing. No wound. Urea loosens. Salicylic acid releases. Your body clears. Two ingredients working at two different levels of the same problem.
What Daily Use of Habsters Can Look Like
-
Week 1-2
You Feel the Difference
The rough, bumpy texture that catches under your fingertips starts to soften. The areas that felt hard and stuck to your skin feel less rigid. You touch your neck or chest and something is different. It's subtle. But you notice.
-
Week 3-4
You See the Change
The raised spots start flattening. The rough patches that used to catch on your bra or snag on your clothing feel smoother. You look in the mirror and the areas that bothered you most are less noticeable. You start checking less.
-
Week 5-8
You Stop Hiding
You reach for the V-neck instead of the high neckline. You don't think twice about it. The dark marks left behind are fading. Your skin feels smoother across your neck, chest, and back than it has in years. You book the massage. You wear the sleeveless top.
-
Week 9-12+
You Feel Like Yourself Again
You stop running your fingers across your skin every morning counting new ones. The bumps no longer control what you wear, how you feel, or how often you check. Your skin feels like yours again. You keep using it because for the first time you have a routine that actually keeps pace.

I Can't Believe That's The Same Skin
"I almost didn't take the before photo. I hated looking at my chest that much. I'd had those raised brown spots for over eight years and they just kept spreading. Every summer I'd layer a cardigan over everything because I couldn't stand people's eyes dropping to my chest and seeing them. My dermatologist froze a few off but they came back and new ones filled in around them. I spent maybe $1,500 over the years on removal and had nothing to show for it. My sister sent me a link to this cream and I honestly rolled my eyes. But I was desperate enough to try. I used it every night for about 10 weeks. The rough ones softened first. Then they started flattening. The dark patches faded. I didn't even notice how much had changed until I put on a V-neck one morning and my daughter said, 'Mom, your chest looks amazing.' I went back and looked at the before photo and I couldn't believe it was the same skin. The right photo is me three months later. No filter. No makeup on my chest. Just skin that finally looks like mine again. I wore that top to dinner and didn't pull it up once."

My Back Was The Part Of My Body I Hated The Most
"I haven't let anyone see my back in over a decade. Not my husband. Not my friends. Not a massage therapist. Nobody. I had so many raised brown spots across my shoulders and upper back that I couldn't even count them anymore. I used to stand in front of the mirror and just stare at it and feel sick. Every shirt I owned had to cover my back completely. I skipped pool parties. I skipped beach trips with my kids. I turned down being a bridesmaid in my best friend's wedding because the dress was backless and I couldn't face it. I tried freezing. I tried ACV. I tried scrubbing them with every exfoliant I could find. Nothing. They just kept coming. A friend told me about this cream and I figured I had nothing left to lose. I started applying it to my back every night. My husband helped me reach the spots I couldn't get to. Around week 5 he said the rough ones felt different. Smoother. Less raised. By week 10 I could see it myself. The dark ones were fading. The thick raised ones were flattening. My back isn't perfect. I'm not pretending it is. But the difference between those two photos is the difference between hiding and living. I pulled my sweater down off my shoulders for the second photo and didn't feel the urge to pull it back up. That's never happened before. I'm 55 years old and I finally don't dread summer."

I'm 72 And My Granddaughter Said My Neck Looks Beautiful
"I've had these spots since my late 50s. They started on my neck and just kept spreading down to my chest. Big dark ones. Raised ones. Rough ones that caught on every neckline I wore. I'm 72. I was told a long time ago to just accept them. That they come with age. That there's nothing to do unless I want to pay hundreds to freeze them off one by one. So I stopped trying. For years I just wore crew necks and scarves and tried not to look in the mirror too long. My daughter ordered this cream for me because I never would have ordered it myself. I didn't think anything could help at my age. She came over twice a week and helped me put it on my neck and chest every night. I didn't notice much the first few weeks. Then around week 6 the rough ones started feeling different. Softer. Less raised. The dark patches started fading. By month 3 I looked in the mirror and my neck looked like it belonged to a different person. Not perfect. I'm not 30. But the thick raised ones that made me feel like everyone was staring at my neck were so much flatter and lighter. My granddaughter was visiting and she looked at me and said, 'Grandma, your neck looks beautiful.' I went to the bathroom and cried. Nobody had said anything nice about my skin in 15 years. I wore a V-neck to church the following Sunday. First time in I don't even know how long."

My Arms Aged 20 Years Before The Rest Of Me
"I'm 49. The rest of me looks 49. But my arms looked like they belonged to someone 70. I had spots all the way down from my shoulder to my elbow. Dark ones. Flat ones. Raised ones. Some the size of a dime, some bigger. They showed up in my early 40s and just exploded from there. I counted over 30 on one arm alone. I stopped wearing anything sleeveless. Even in July. Even at home. If my husband and I went out to dinner I'd grab a cardigan no matter how hot it was. I became that woman who always had her arms covered and nobody knew why. I didn't talk about it because honestly I was embarrassed that it even bothered me this much. My doctor said they were harmless. Great. They still made me feel like my arms were rotting. Sorry but that's how it felt. I found this cream after going down a rabbit hole at midnight one night. I started putting it on both arms every night. Around week 4 the raised ones started softening. By week 8 the dark ones were noticeably lighter. They're not gone. You can see that in the after photo. But look at the difference. The big dark ones faded. The raised bumps flattened. My arms look like my arms again. Not perfect. But mine. I wore a sleeveless top to brunch last weekend and didn't think about it until I was already in the car. That's the part that gets me. I just forgot to worry about it."

I Stopped Pulling My Collar Up Every Time Someone Talked To Me
"I'm not the kind of guy who buys skincare products. Never have been. But these spots on my neck and chest got to a point where I couldn't ignore them anymore. They started in my early 50s. A few dark spots near my collarbone. No big deal. Then they spread. Up my neck. Across my chest. Dark, rough, raised. I looked like something was wrong with me. I started wearing crew necks to work. Buttoned my shirts all the way up. At the beach I'd keep my shirt on. If someone stood close to me in conversation I'd catch myself pulling my collar up without thinking. My wife noticed. She said I'd been doing it for years. I didn't even realize. My doctor said they're harmless and that removal would cost a fortune because I had so many. So I did nothing. For five years I did absolutely nothing except cover them up. My wife found this cream online and put it on the bathroom counter. I started using it at night. Didn't tell anyone. Didn't expect anything. Around week 6 the raised ones on my neck felt smoother. The rough texture was softening. By month 3 the dark spots had faded enough that I could see my actual skin tone again. I'm not going to pretend they disappeared. They didn't. But look at the difference. My neck looks like a normal neck again. Last week I wore a V-neck to a barbecue and my buddy said I looked good. I just said thanks. Didn't explain. Didn't need to.

Powered by Nature's & Science Most Effective Ingredients
Everything your regular cream is missing. The right ingredients, at the right concentrations, for rough, raised skin that nothing else has been able to reach
40% Urea
2% Salicylic Acid
Green Tea Extract
Aloe Vera Extract
Tea Tree Oil
Coconut Oil
40% Urea
Disrupts the hydrogen bonds inside compacted keratin that makes SKs feel thick, raised, and stuck to your skin. At this concentration it crosses from moisturizer to keratolytic, softening the dense structure from within where no regular cream can reach.
2% Salicylic Acid
Dissolves the intercellular glue holding keratinized cells together. Once urea softens the keratin, salicylic acid releases the loosened cells so your body sheds them naturally. Gentle enough for daily use but targeted enough to work on stubborn SK buildup.
Green Tea Extract
Calms the redness and irritation that builds up around SKs, especially after years of picking, scratching, and failed treatments. Reduces inflammation in the surrounding skin so the active ingredients can work without discomfort.
Aloe Vera Extract
Replenishes moisture in the treated area while the keratin is being broken down. SKs and the skin around them are often dry, rough, and compromised. Aloe creates a hydration barrier so healthy skin stays nourished while the formula targets the growth.
Tea Tree Oil
Addresses the dark pigmentation that SKs leave behind. Even after the rough texture flattens, the darkened skin tone can make the area still look aged and uneven. Tea tree oil helps fade melanin deposits and restore a more natural, even appearance.
Coconut Oil
Repairs skin that has been damaged by the growths themselves and by everything she's tried before, the burning from ACV, the scabbing from freeze spray, the irritation from wart remover. Rich in fatty acids that rebuild the skin barrier and help treated areas heal smoother.
Habsters works, while others miss the mark.

Frequently Asked Questions
Will this work for my skin type?
Will this work for my skin type?
Yes — the formula is designed for all skin types. It combines keratolytic actives (urea and salicylic acid) with soothing ingredients (aloe vera, coconut oil, vitamin E) that protect your skin during treatment.
Apply only on affected spots — not on surrounding healthy skin, and never on the face. We recommend starting with once daily application, then building up to twice daily based on how your skin responds. If you have very sensitive or reactive skin, always patch test on a small spot first.
How long does one jar last?
How long does one jar last?
It depends on how many spots you're treating. Someone with a few patches on their neck might stretch a jar for 2 months. Someone treating their neck, chest, back, and arms will go through it faster.
Most customers start with once a day while their skin adjusts, which makes one jar last about 2 months.
Once you start seeing results and move to twice a day, one jar lasts about 1 month.
Can I use this alongside my other skincare products?
Can I use this alongside my other skincare products?
Yes, but don't layer it with other strong actives like retinoids or acid treatments on the same area at the same time. That's too much exfoliation in one spot.
If you use those products on other parts of your body, that's completely fine. Just introduce SK Renewal 40 gradually, let your skin adjust, and always follow with a moisturizer on the surrounding skin.
Is it safe to use on sensitive areas like underarms and the bikini line?
Is it safe to use on sensitive areas like underarms and the bikini line?
We recommend starting on less sensitive areas first, like your neck, chest, back, or arms. 40% urea is a strong keratolytic, and thinner skin in areas like the underarms and bikini line may be more reactive.
If you want to try it on a sensitive area, do a small patch test first and wait 24 hours. If there's no irritation, apply once every other day and let your skin adjust before increasing. If you experience any burning or redness, stop use on that area.
Note: Do not apply on the face.
What if I don't see results?
What if I don't see results?
Give it time. This formula softens compacted keratin from within, which is a gradual process. Most people feel a difference in the first 2 to 4 weeks. Visible flattening and smoothing typically happens between week 6 and 12. Make sure you're applying consistently and not skipping days.
If you've used it for 90 days and don't see a difference, we'll refund you in full. No questions, no hassle.
What ages is this suitable for?
What ages is this suitable for?
SK Renewal 40 is suitable for adults of all ages who have seborrheic keratoses. Most of our customers are between 35 and 70, which is when these growths tend to multiply and become more noticeable. Some customers in their late 20s and early 30s use it after developing early growths during pregnancy or hormonal changes.
As long as your spots have been identified as seborrheic keratoses and not something else, age isn't a limitation. We do not recommend it for children under 18.
Does it hurt or irritate my skin?
Does it hurt or irritate my skin?
No. Despite the name, salicylic acid at 2% is the same gentle concentration found in everyday acne cleansers. And urea, even at 40%, is not an acid at all. It's a compound your body already produces naturally. There's no freezing, no burning, no scabbing.
Some people feel a mild tingling during the first few applications while their skin adjusts. That's normal and usually goes away within a few days. If you have very sensitive skin, start with once every other day and work your way up. If any redness or discomfort persists, stop use on that area.
Does it leave scars?
Does it leave scars?
No. That's one of the biggest differences between this and professional removal. Cryotherapy, burning, and scraping destroy the growth from the outside, which can leave scars, dark marks, or light patches on your skin.
SK Renewal 40 works differently. It softens the keratin from within and lets your body shed the loosened cells naturally. There's no wound. No scab. No healing period. Your skin does the clearing on its own, so the risk of scarring is virtually zero.
