How To Use
First Time? Pick one small spot. Apply a thin layer. Give it a little time. A gentle tingle means it's working, totally normal. Once it feels good, treat all your other spots.
Daily Routine
- Wash the area and pat dry
- Dab directly on each spot — thin layer for flat spots, generous layer for thick raised ones
- Rub in gently until absorbed
- Once daily for the first week — twice daily once your skin is comfortable
Tips
- Treat all spots in one session — neck, chest, back, arms, legs, hands, elbows, knees
- Apply on the spot only, not the skin around it
- Body use only — keep it below the jawline
- Avoid cuts, open wounds, or freshly shaved areas
- Use sunscreen on treated areas during the day
- Keep away from eyes and out of reach of children
Your Journey
- Week 1–2: Spots start softening
- Week 2–4: Visible flattening
- Week 4+: Keep going — consistency is everything

What if it doesn't work for me?
What if it doesn't work for me?
Then you don't pay for it. Use the full jar for 90 days. If your spots aren't visibly softer and flatter, email us one photo and we'll refund every cent, and you keep the jar.
We built it this way because we know you've probably wasted money before on things that did nothing. You shouldn't have to gamble again. The only thing you're risking is the time it takes to try it.

Join 10,000+ Who Reduced Their Rough, Raised Spots With Habsters!
Seborrheic Keratoses/Barnacles/Rough,Raised Spots
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.
Skin That Feels Like Skin Again
What Changes When You Start Using SK Renewal 40
Professional removal costs $150 to $300 per spot. And they come back. And new ones appear. SK Renewal 40 covers every area, every night, for a fraction of the cost of a single session. One jar. Every spot. No appointments.
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.
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.

Powered by Nature's & Science Most Effective Ingredients
Everything your regular cream is missing. The right ingredients, at the right concentrations, for targeted results.
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.
Wobea works, while others miss the mark.

Your Questions Resolved
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.
I'm in my 70s — is it too late for me?
I'm in my 70s — is it too late for me?
It's not too late. The process works the same at 75 as it does at 45 — older spots have simply been building longer, so they take a little more time to soften and fade. Some of our most dramatic before-and-afters are women in their 70s who'd spent years being told nothing could be done. Nothing about your age makes your skin the exception.
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.
