Perianal Skincare: Don't Fall Through the Cracks
Perianal Skincare: Don't Fall Through the Cracks
What's causing that itchy rash — and what you're probably doing to make it worse without realizing it
An itchy red rash around the perianal area — perianal dermatitis — can have many different causes: irritant or allergic contact dermatitis, seborrheic dermatitis, psoriasis, lichen planus, early lichen sclerosus, or infections like tinea (ringworm). To get properly diagnosed, you will need to see a dermatologist. But there is plenty you can do before and after that visit to stop making things worse — and most people are actively aggravating the area without even realizing it.
A rash on the perianal area means the skin barrier is compromised — the upper layers of the skin are either missing or deficient. That means the less you do to undermine them, the better your chances of recovery. The first and most important rule is: do no harm.
Things People Do "Without Doing Anything"
When patients with perianal rashes tell me they're not doing anything to the area — 99% of the time, they are. Here is the list of things that people who claim to do "nothing" actually do — all of which can aggravate a perianal rash:
⚠️ Stop Applying All of These
- Wet wipes — prepackaged water-based wipes contain preservatives and additives that cause irritation in sensitive perianal skin
- Medicated creams and ointments — triple antibiotic, antifungals, Preparation H, anti-itch creams, or old prescriptions. Do not apply without a confirmed current diagnosis
- Disinfectants — alcohol, hydrogen peroxide, and similar agents damage the barrier and worsen the problem
- Over-the-counter moisturizers — most lotions, creams, ointments, and balms contain far too many ingredients with irritation potential
- Lubricants — water-based lubricants with preservatives are particularly problematic for compromised perianal skin
- Inserting objects — take a pause. Let the tissue recover.

What to Do Instead
If You Use Soap — Minimize It
Avoid scrubbing devices and antibacterial soaps entirely. If soap is needed at all, use a minimalist, gentle option — something like Kiss My Face olive oil soap — used sparingly and only around the area, not on it. Consult your dermatologist about whether soap is even appropriate for your specific situation. Most often, it isn't.
Protect the Area with a Minimalist Oil-Based Product
When the area needs moisture and protection, use a clean oil-based product with the fewest possible ingredients — Butter Oasis, Butter Blossom, petroleum jelly, or zinc oxide ointment. These provide a protective barrier without the preservatives, emulsifiers, and additives of water-based products.
Wipe Gently and Carefully
Friction is a significant aggravating factor. Use soft, unscented three-ply toilet paper — or a soft paper towel dampened with lukewarm water or coconut oil. Prepackaged coconut oil wipes are a solid option. Avoid all scented products and anything that involves rubbing rather than gentle patting.
🩺 The Bottom Line
Your perianal condition must ultimately be treated according to the correct diagnosis. Be very careful with shotgun approaches — applying everything in the medicine cabinet and hoping for a miracle. Every choice has consequences. There is no "nothing." Think twice about every practice in the area, eliminate everything that isn't clearly helping, and see your board-certified dermatologist to get the diagnosis right.
