Dr Dennis Gross Instant Radiance Sun Defense Sunscreen Broad Spectrum SPF40 by Dr Dennis Gross

This product offers a good level of protection against both UVB and UVA rays.

It is a mineral sunscreen. In other words, it contains non-organic UV filters. It will probably not sting your eyes but might leave a white cast.

This product can be considered "reef safe" because it does not contain the UV filters (oxybenzone and octinoxate) that can be harmful to coral reefs when present in the water in high concentrations.

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains glycolic acid.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: palmitoyl tripeptide-38.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

This product can also help prevent early signs of skin aging because it offers a good level of broad spectrum sun protection. Sun damage is the main cause of premature skin aging, and protecting your skin from the sun is the best anti-aging strategy.

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: glycerin, saccharide isomerate.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: carthamus tinctorius seed oil, glycine soja oil.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: palmitoyl tripeptide-38

This product offers broad spectrum sun protection. It means that it can prevent hyperpigmentation and help keep the skin tone even (sun damage is the main factor causing age spots, darkening of post-acne marks and other discolorations).

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: glycolic acid.

This product contains antioxidants (melatonin) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
