Colloidal Oatmeal (Topical)

Reviewed by the Nimbera editorial team · Last updated May 2026

Fowler 2012 J Drugs Dermatol (PMID 22777219) - Multi-age clinical series showed colloidal oatmeal moisturizers and cleansers produced meaningful improvements in EASI scores, IGA ratings, itch, and dryness from baseline across infants, children, and adults with mild-to-moderate atopic dermatitis, with a good tolerability profile.$15-25/month

How to use

Apply a 1% colloidal oatmeal cream or lotion to affected skin 2-3 times daily, especially immediately after bathing while skin is still slightly damp. For oatmeal baths, add 1 cup of finely ground colloidal oatmeal to lukewarm (not hot) bathwater and soak for 10-15 minutes. Pat skin dry gently - do not rub.

How it works

Colloidal oatmeal contains avenanthramides, beta-glucan, and lipids that restore the skin barrier, reduce transepidermal water loss, and suppress inflammatory cytokine release. It also has mild antihistamine properties that reduce itch signaling.

Where to buy

Aveeno Eczema Therapy Daily Moisturizing Cream (~$14-18 / 8 oz), CeraVe Itch Relief Moisturizing Lotion (~$16 / 8 oz), Eucerin Eczema Relief Cream (~$15 / 8 oz), Burt's Bees Baby Eczema Lotion (~$12 / 6 oz). Generic colloidal oatmeal bath packets available at most pharmacies for ~$8-12 per box.

Typical cost: $15-25/month

Safety notes

Oat allergy (rare but possible - especially in those with celiac disease or wheat allergy). Patch test on a small area of skin before widespread use. Not a substitute for prescribed corticosteroids during severe flares. Avoid hot baths which can worsen eczema.
