? How do I use Dernavex?

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 your other spots.

Daily Routine

  1. Wash the area and pat dry
  2. Dab directly on each spot — thin layer for flat spots, generous layer for thick raised ones
  3. Rub in gently until absorbed
  4. 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

    • 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

      "My back was the one part of me nobody got to see. Not my husband, not a massage therapist, no one. I couldn't even count the spots across my shoulders anymore, and I'd genuinely turned down being a bridesmaid once because the dress was backless and I couldn't face it. So my expectations here were basically zero.

      My husband put this on every night on the spots I couldn't reach. Around week 5 he said they felt smoother, less raised, I didn't fully believe him until week 10 when I could finally see it in the mirror myself. Look at the two photos. The dark ones faded, the thick raised ones flattened.

      I'll be honest, it's not perfect and it took longer than I wanted, I was hoping for a month and it was closer to three. And it's not cheap. But it's the only thing in a decade that did anything at all, so I'm not complaining much. I'm 55 and I don't dread summer for the first time in forever."

    • 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."

      This Formula Was Built For These Three Problems

      For Years There Was No Real Answer. Then 40% Urea Changed Everything

       

      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.

      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.

      What Daily Use of Dernavex 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 helps you.

      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.

      Dernavex cream with six key ingredients
      40% Urea ingredient icon

      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.

      60-Day "Smooth Skin" Guarantee

      We give you 60 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 60 days because that gives you the full timeline to see real results. Not rushed. Not pressured. Just enough time to let the formula do what it was designed to do.

      We can offer this because most people don’t send it back. They reorder.

      Your Questions Resolved

      Frequently Asked Questions

      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?

      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?

      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 Dernavex 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?

      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?

      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.

      What ages is this suitable for?

      Dernavex is suitable for adults of all ages who have seborrheic keratoses. Most of our customers are between 35 and 70.

      We do not recommend it for children under 18.

      Does it hurt or irritate my skin?

      Some people feel mild tingling during the first few applications while their skin adjusts. If redness or discomfort persists, stop use on that area.

      Does it leave scars?

      Dernavex is a topical cosmetic product and does not involve freezing, burning, scraping, or cutting the skin.

      Follow the application instructions carefully and discontinue use if persistent irritation develops.
