What's the Best Sunscreen for Babies?

The Short Answer

The best sunscreen for babies is none at all if they are under 6 months old. According to the FDA and American Academy of Pediatrics (AAP), infants under 6 months should be kept in the shade with UPF clothing because their skin is highly permeable and they cannot safely metabolize active sunscreen ingredients.

Once they hit the 6-month mark, the best option is a fragrance-free, mineral sunscreen with at least 20% non-nano zinc oxide. Because an infant's skin is 30% thinner than an adult's, you must avoid chemical filters completely to prevent toxic absorption. Mineral Vs Chemical Safer

Why This Matters

A baby's skin barrier is still developing, making it incredibly vulnerable to the outside world. What you put on an infant's skin is rapidly absorbed directly into their bloodstream. This makes the synthetic filters found in conventional sunscreens a serious hazard for tiny bodies. Chemical Sunscreen Bloodstream

Heat regulation is another major concern for infants. Slathering a young baby in thick sunscreen can trap heat and prevent them from sweating. This dramatically increases their risk of overheating and heatstroke during warm summer days, which is why physical shade is heavily preferred.

Finally, the stakes for sun protection are incredibly high in childhood. Just one blistering sunburn in early childhood can nearly double a person's lifetime risk of developing melanoma. Finding a safe, effective sunscreen is non-negotiable once your baby is old enough to safely wear it. Is Sunscreen Safe

What's Actually In Baby Sunscreen

• Zinc Oxide — The gold standard for baby sun protection. It physically sits on top of the skin rather than absorbing into the bloodstream, blocking both UVA and UVB rays. Is Zinc Oxide Safe
• Titanium Dioxide — A safe mineral filter, though less broad-spectrum than zinc. It is often used alongside zinc oxide for maximum sun coverage. Is Titanium Dioxide Safe
• Oxybenzone — A chemical UV filter that easily penetrates the skin and acts as a known hormone disruptor. Never use this on a baby. Is Oxybenzone Safe
• Avobenzone — A common chemical filter used in modern sunscreens, but still not recommended for infants due to the risk of skin irritation and systemic absorption. Is Avobenzone Safe
• Fragrance — Synthetic scents added to mask raw ingredient smells. They are completely unnecessary and act as a leading cause of contact dermatitis in infants.

What to Look For

Green Flags:

• Non-nano Zinc Oxide — Look for concentrations around 20%. These mineral particles are intentionally too large to cross the infant skin barrier. Nanoparticles Sunscreen
• EWG Verification — Seek out products with an EWG rating of 1. In 2025, only 43 baby sunscreens met the Environmental Working Group's strict safety standards.
• Fragrance-Free — Hypoallergenic formulas protect against allergic reactions. Always choose formulas completely free of synthetic fragrances or irritating essential oils.

Red Flags:

• Chemical Filters — Avoid anything with oxybenzone, octinoxate, octocrylene, or homosalate. These are absorbed too easily by thin baby skin. Sunscreen Ingredients Avoid
• Aerosol Sprays — Sprays pose a significant inhalation risk for small, developing lungs and often provide spotty, inadequate coverage.
• SPF Above 50 — Ultra-high SPF ratings offer minimal extra protection but require much higher concentrations of heavy ingredients that can irritate the skin. Spf 100 Vs 50

The Best Options

When your baby is ready for sunscreen, these mineral options are trusted by pediatricians, formulated specifically for sensitive skin, and highly rated by the EWG.

The Bottom Line

1. Wait until 6 months. Rely entirely on shade, stroller canopies, and UPF clothing until your baby reaches the half-year mark.

2. Go 100% mineral. Only use non-nano zinc oxide or titanium dioxide formulas to prevent dangerous chemical absorption.

3. Skip the sprays. Stick to thick creams or solid sunscreen sticks to avoid accidental lung inhalation by your baby.

FAQ

Can I put sunscreen on my 3-month-old?

No, the FDA and AAP strongly advise against sunscreen for babies under 6 months. Their skin is too thin and absorbs chemicals too easily, plus the thick creams can cause them to dangerously overheat. Keep them completely in the shade instead.

What's the best sunscreen for a baby with eczema?

Look for a gentle colloidal oatmeal and zinc oxide blend. Brands like Babo Botanicals and Earth Mama make extremely gentle, fragrance-free formulas that will protect their skin without triggering angry flare-ups. Best Sensitive Skin Sunscreen

Do I need to wash sunscreen off my baby?

Yes, you should wash mineral sunscreen off at the end of the day. Since zinc oxide acts as a physical barrier that sits on top of the skin, a gentle baby wash and warm water will remove the residue and let their pores breathe.
