Is Blue Lizard Sunscreen Safe?

The Short Answer

Blue Lizard is a solid middle-ground sunscreen, but it isn't completely clean. It's vastly superior to drugstore chemical sunscreens, but purists should read the labels carefully.

While the active ingredients are purely mineral, the brand's popular SPF 50 lotions rely on butyloctyl salicylate—a chemical SPF booster hidden in the inactive ingredients list. If you want a truly clean product from this brand, stick to their Kids Mineral Sunscreen Stick, which avoids these sneaky additives and scores a low hazard rating from the EWG.

Why This Matters

For years, Blue Lizard has been the holy grail of pediatrician recommendations. It's marketed heavily as a pure, sensitive-skin-friendly mineral sunscreen. Best Sunscreen Babies

But the formulation has evolved. To achieve that coveted SPF 50 rating without turning your skin stark white, most mineral brands now use chemical boosters. Because these compounds aren't officially classified as UV filters by the FDA, brands can legally call their products "100% mineral" while still including them. Safest Sunscreen

Furthermore, despite the name and the cool color-changing bottle, Blue Lizard is no longer an Australian product. It is manufactured in the United States and does not have to comply with Australia's notoriously strict therapeutic goods regulations.

What's Actually In Blue Lizard Sunscreen

The active ingredients in Blue Lizard's "Sensitive" and "Baby" lines are genuinely excellent. It's the inactive ingredients that bump most of their lotions into the EWG's "Moderate Hazard" category.

• Zinc Oxide (10%) & Titanium Dioxide (8%) — The gold standard for safe, broad-spectrum UV protection. These minerals sit on top of the skin rather than absorbing into the bloodstream. Is Zinc Oxide Safe
• Butyloctyl Salicylate — A chemical structurally nearly identical to the chemical filter octisalate. It boosts the SPF rating so the brand can use less zinc oxide, but it carries similar allergy and absorption concerns as traditional chemical filters. Mineral Vs Chemical Safer
• PEG-7 Hydrogenated Castor Oil — A synthetic emulsifier. PEGs can sometimes be contaminated with 1,4-dioxane, a known carcinogen, depending on how they are processed.
• Chlorphenesin — A synthetic preservative used to prevent bacteria growth. It can cause skin irritation and contact dermatitis in sensitive individuals.

What to Look For

Green Flags:

• Zinc Oxide — The safest, most effective broad-spectrum UV filter available.
• Titanium Dioxide — An excellent secondary mineral filter that helps boost UVB protection. Is Titanium Dioxide Safe
• Paraben & Fragrance-Free — Blue Lizard has successfully removed controversial parabens and artificial fragrances from their sensitive lines.

Red Flags:

• Spray Formulations — Blue Lizard's spray sunscreens pose a severe inhalation risk. Mineral particles are safe on the skin but can cause lung damage if inhaled.
• Butyloctyl Salicylate — If you want to avoid chemical filters completely, you have to avoid this chemical booster.
• "Active" or "Sport" Non-Mineral Lotions — While Blue Lizard is famous for its mineral line, they still sell some hybrid or pure chemical formulas. Always check for the word "Mineral" on the bottle.

The Best Options

If you are going to buy Blue Lizard, skip the SPF 50 lotions and the sprays. The sunscreen sticks are where the brand actually shines.

The Bottom Line

1. Stick to the sticks. The Blue Lizard Kids Mineral Stick is the cleanest product in their lineup.

2. Watch out for SPF 50 mineral lotions. To get high SPF without a chalky white cast, Blue Lizard relies on chemical boosters like butyloctyl salicylate.

3. Never spray minerals. Avoid their aerosol and pump sprays entirely to protect your lungs from aerosolized titanium dioxide.

FAQ

Is Blue Lizard really reef safe?

Technically yes, but practically it's complicated. Blue Lizard does not use oxybenzone or octinoxate, the two chemicals officially banned in places like Hawaii. However, research shows that high concentrations of any sunscreen, including zinc oxide, can still cause stress to fragile marine ecosystems. Reef Safe Sunscreens

Why did Blue Lizard get a moderate EWG rating?

Most of Blue Lizard's lotions score a moderate hazard rating from the EWG. This is primarily due to their use of synthetic inactive ingredients like PEGs, chemical boosters, and preservatives, rather than the active UV filters themselves.

Does Blue Lizard leave a white cast?

Yes, especially the pure mineral stick formulas. Because the brand relies on 10% zinc oxide and 8% titanium dioxide, the un-boosted versions will leave a visible white residue. Formulas that rub in perfectly clear usually rely heavily on chemical boosters. Mineral White Cast
