Red Bumps on Upper Arms: Understanding and Managing Keratosis Pilaris

As warmer weather hits and we bare our arms, those stubborn red bumps on the upper arms can be frustrating. As a dermatology expert, I've helped countless patients identify and treat this common issue. Here's what you need to know and how to address it effectively.

Keratosis Pilaris Explained
Keratosis pilaris is a harmless yet common skin condition where excess keratin builds up around hair follicles, forming small, rough red bumps. It affects the texture of the skin, often making it feel like sandpaper.

You're Not Alone
This condition impacts millions, typically appearing on the backs of the upper arms, but it can also show up on thighs, cheeks, buttocks, or back. While there's no cure, symptoms can be significantly improved with consistent care.

Expert Skin Care Tips for Keratosis Pilaris

1. Gently exfoliate using products with salicylic acid or alpha/beta hydroxy acids (AHA/BHA) to smooth the skin.
2. For manual exfoliation, opt for a soft washcloth or mild scrub—avoid aggressive scrubbing to prevent irritation.
3. After showering, lock in moisture with a rich, emollient cream containing urea or lactic acid.
4. Resist scratching bumps or dry patches to avoid worsening inflammation.
5. Consult a dermatologist for personalized treatments like prescription topicals if needed.
