Baby acne is largely driven by hormones and can’t be fully prevented. About 20% of newborns develop it, typically between 2 and 4 weeks after birth, and it clears up on its own without treatment. The good news: while you can’t stop it from appearing, you can keep it mild and help it resolve faster with a few simple skin care habits.
Why Baby Acne Happens
Your newborn’s adrenal glands are proportionally large at birth and produce high levels of androgens, a type of hormone that stimulates oil-producing glands in the skin. Both maternal hormones (passed during pregnancy) and your baby’s own hormones contribute to this effect, causing the sebaceous glands to enlarge and pump out extra oil. This is the same basic mechanism behind teenage acne, just triggered by a different hormonal surge.
The adrenal glands gradually shrink over the first year of life, and androgen levels drop along with them. That’s why neonatal acne is temporary. Boys are affected more often than girls because testicular androgens provide additional stimulation to those oil glands.
Because the root cause is hormonal, no amount of skin care will guarantee your baby won’t get a few bumps. But the practices below reduce irritation, keep pores clear, and prevent mild breakouts from getting worse.
Daily Skin Care That Helps
Wash your baby’s face once a day with warm water. The Mayo Clinic recommends alternating between plain warm water one day and warm water with a mild, moisturizing facial soap the next. This removes excess oil without stripping the skin. Pat the face dry gently with a soft cloth rather than rubbing.
Avoid scrubbing. A baby’s skin is thin and easily irritated, and friction can inflame existing bumps or trigger new ones. Use your fingertips or a soft washcloth with light pressure.
Products to Skip
Lotions, oils, and heavy creams can clog your baby’s pores and make acne worse. Unless your pediatrician specifically recommends a product, keep your baby’s face free of anything beyond the gentle cleanser mentioned above. This includes “natural” oils like coconut oil, which can still block pores on infant skin. Over-the-counter acne treatments designed for older children or adults are too harsh for newborns and should never be applied.
Reducing Irritation From Fabrics and Spit-Up
Drool, spit-up, and rough fabrics sit on your baby’s skin and can aggravate breakouts. Gently wipe your baby’s face with a damp cloth after feedings, especially around the cheeks and chin where milk residue tends to collect. Use soft, breathable fabrics for burp cloths, bibs, and anything that regularly touches your baby’s face. Wash these items with a fragrance-free detergent to minimize chemical irritation.
Overheating can also worsen skin irritation in general. Dress your baby in layers appropriate for the temperature, and avoid bundling them in heavy fabrics that trap heat against their face and neck.
What Baby Acne Looks Like
Neonatal acne typically appears as small closed bumps (whiteheads) on the forehead, nose, and cheeks. Some babies also develop open blackheads or red, slightly inflamed bumps. The breakouts look a lot like mild teenage acne, just on a much smaller face.
Not every bump on a newborn’s skin is acne. Two other common conditions can look similar:
- Milia: Tiny (1 to 2 mm) pearly white or yellow dots, most often on the nose, cheeks, and chin. These are caused by trapped skin cells, not oil, and they resolve on their own within a few weeks.
- Erythema toxicum: Red, blotchy patches with small pustules that give a “flea-bitten” appearance. These show up on the face, trunk, and upper arms but never on the palms or soles. They’re completely harmless and disappear without treatment.
If you’re unsure which rash your baby has, your pediatrician can tell the difference with a quick visual exam.
When It Lasts Longer Than Expected
Most neonatal acne clears within a few weeks to a couple of months. If breakouts persist beyond 3 months, or if you notice deeper, cyst-like bumps or nodules rather than small surface-level whiteheads, your baby may have what’s called infantile acne. This is a separate condition that can last longer and occasionally needs treatment to prevent scarring. A pediatric dermatologist can evaluate whether any intervention is needed and rule out uncommon hormonal issues.
The Short Version of Prevention
You can’t eliminate the hormonal trigger, but you can create conditions where your baby’s skin stays as clear as possible. Wash once daily with warm water, alternate in a mild soap every other day, skip lotions and oils on the face, wipe away milk residue promptly, and keep fabrics soft and clean. For the 20% of newborns who still develop acne despite all of this, patience is the most effective treatment. The bumps almost always resolve on their own as your baby’s hormone levels naturally settle down.
