Yes. Cerva is built for all skin types. The formula pairs two keratolytic actives — 40% urea and 2% salicylic acid — with calming botanicals like aloe vera, coconut oil, green tea, and tea tree oil to keep your skin comfortable while the actives do their work.

Use it only on the spots themselves, not the healthy skin around them, and never on your face. Start with one application per day. Once your skin has adjusted, you can increase to twice daily if needed. If your skin tends to be reactive, test a small area first and give it 24 hours before committing

That depends on how much ground you're covering. If you're treating a few spots on your neck, a single jar can last around two months. If you're applying across your chest, back, shoulders, and arms, you'll go through it quicker.

At once a day — which is where most people start — one jar runs about two months. Once you bump up to twice a day, expect closer to one month per jar.

Absolutely — just don't stack it with other strong exfoliants like retinoids or acid serums on the same patch of skin. Doubling up actives in one area is asking for irritation.

Using those products elsewhere on your body is perfectly fine. Ease Cerva into your routine slowly, give your skin a few days to adjust, and apply a moisturizer to the surrounding skin after each use.

Start with less reactive areas first — neck, chest, back, arms. At 40% concentration, urea is a serious keratolytic, and thinner skin in folds or creases is more likely to react.

If you do want to try a sensitive area, patch test a small spot and wait a full day. No reaction? Apply every other day and build from there. Any burning or lasting redness means stop on that area.

Do not use on the face.

Not at all. The chemistry doesn't care how old you are. Urea breaks down compacted keratin the same way whether you're 45 or 80. Spots that have been building for decades just take a bit longer to soften and clear — but they still respond.

Some of our best results have come from women in their 70s who were told for years there was nothing they could do. Your age is not a disqualifier.

No. The 2% salicylic acid is the same mild concentration you'd find in a drugstore acne wash. And urea — even at 40% — isn't an acid. It's something your body produces on its own. Nothing about this formula burns, freezes, or cuts.

A light tingle during your first few applications is normal. That fades within a few days as your skin adjusts. If you're prone to sensitivity, start every other day and work up gradually. If irritation sticks around, stop using it on that area.

No — and that's a major advantage over professional removal. Cryotherapy, cauterization, and scraping all attack the growth from the outside in. That kind of force can leave scars, discoloration, or uneven texture behind.

Cerva works from the inside out. It loosens the compacted keratin so your body can shed it naturally. No wound, no scab, no recovery window. Because the skin is never broken, the chance of scarring is essentially zero.
