TIZO AM Replenish SPF 40 is a 100% mineral, physical sunscreen. Its only active ingredient is zinc oxide at 16%, which means it protects by sitting on the surface of the skin and reflecting UV rays rather than converting them through a chemical reaction. This makes it a good option for those who prefer to avoid chemical UV filters.

Yes. Because TIZO AM Replenish SPF 40 uses zinc oxide as its sole active ingredient and contains no oxybenzone or octinoxate, it is considered reef-friendly. These are the chemical filters most associated with coral reef damage, and this formula avoids them entirely.

Ceramide 3 is a lipid naturally found in the skin's barrier layer. In TIZO AM Replenish SPF 40, it helps replenish the skin's natural lipid content, supporting moisture retention and overall barrier integrity. Daily use of a ceramide-containing SPF can help keep the skin feeling comfortable and less prone to sensitivity caused by barrier disruption.

TIZO AM Replenish SPF 40 contains tetrahexyldecyl ascorbate, an oil-soluble, highly stable derivative of vitamin C. Unlike L-ascorbic acid, which is water-soluble and prone to oxidation, tetrahexyldecyl ascorbate remains stable in formulation and penetrates the skin effectively to neutralize free radical damage. This is a meaningful distinction because many vitamin C forms degrade quickly and lose their efficacy before they reach the skin.

Yes, and it performs particularly well as a makeup base. The silicone-rich formula creates a smooth, even surface that helps foundation apply more evenly and adhere longer. The finish is not greasy or heavy, so it layers cleanly under powder or liquid formulas without causing pilling.

It is formulated with this in mind. Zinc oxide is widely regarded as one of the most skin-tolerant UV filters available, and the formula is free of fragrance and chemical sunscreen actives, both common sources of irritation. If you have reactive or easily sensitized skin, mineral sunscreens like this one are typically the recommended starting point.

For consistent protection, reapply TIZO AM Replenish SPF 40 every 2 hours when you are exposed to sunlight. It is not waterproof, so reapplication is especially important after sweating or any contact with water. For a typical indoor day with limited sun exposure, a single morning application is standard, though reapplication is still best practice any time you step outside.
