Product summary

Based on the ingredient list, we assess that "Bayer - Coppertone Sport Sunscreen Lotion, SPF 50" can provide reliable sun protection. It can protect from both UVA and UVB rays. This is great news because not all sunscreens with SPF ratings give UVA protection. (UVA rays do not cause sunburn, but still damage our skin and lead to early aging).

It also works as a moisturizer, so you do not have to use an additional hydrating product. Like all broad-spectrum sunscreens, this product has an anti-aging benefit.

Sunscreen filters

This sunscreen uses so-called "chemical", or organic UV filters (organic simply means that their molecules contain atoms of carbon). These filters typically give good sun protection and rarely leave a white cast, but they can be irritating for sensitive skin. These are the sun protection ingredients in this sunscreen: avobenzone 3.00% (declared), octisalate 4.50% (declared), homosalate 8.00% (declared) and octocrylene 6.00% (declared).

Sodium ascorbyl phosphateA stable derivative of vitamin C. It is oil-soluble which means it is more likely to penetrate the skin compared to the pure form of vitamin C (which is water-soluble), but it is less bio-available and is way less effective in stimulating collagen and reducing wrinkles compared to the pure form of vitamin C (L-ascorbic acid) and its other derivatives (for example, magnesium ascorbyl phosphate). At the same time, this vitamin C derivative has been shown in studies to be effective in reducing acne, blemishes and clogged pores. It is less irritating then the pure form of vitamin CLow~0.25–0.45%est.
