Tips for Parents

Keep skincare simple and gentle
- Use lukewarm water and a mild, fragrance‑free baby cleanser once daily on the face.3 4 6
- Avoid scrubbing, loofahs, or washcloths with heavy friction.2 3
Skip acne products and harsh actives
- Do not use adult or teen acne treatments (benzoyl peroxide, salicylic acid, retinoids) unless your pediatrician specifically recommends them.3 6 9
- Avoid “degreasing” with strong soaps or astringents—these strip the barrier and may worsen irritation.3 4
Avoid heavy, oily lotions on acne‑prone areas
- Oils and thick occlusives can clog pores and make baby acne appear worse.4 6
- For eczema‑type dryness elsewhere, choose fragrance‑free, sensitive‑skin moisturizers.7 8
Watch fragrance and unnecessary additives
- Some babies react to fragrances and certain preservatives in soaps, wipes, and detergents.4 7
- Choose products labeled for sensitive skin and avoid talc or cornstarch powders, which can be inhaled or irritate skin.7
- You can read more on powders and irritants in “Is Talc Free Powder Actually Safe? The Cornstarch Debate” on our blog.
Dress for comfort, not Instagram
- Opt for soft, breathable cotton and avoid tight, synthetic outfits that trap sweat.2 7
- In warm weather, keep the room cool and well‑ventilated to minimize heat rash.2 7
Hands off the bumps
- Don’t squeeze, pick, or “scrub them off”—this can lead to infection and irritation.4 6 7
- Keep baby’s nails short to prevent scratching.6 7
Know the red flags
Contact your pediatrician promptly if you notice:1 7 10
- Fever, lethargy, or baby seems very unwell
- Blisters, open sores, or yellow crusting (possible infection)
- Rash that rapidly spreads, bruises, or purple spots
- Swelling of lips, eyelids, or any breathing difficulty (emergency)
