We assess that "Peter Thomas Roth - Instant Mineral Broad Spectrum SPF 45 Sunscreen" can provide reliable sun protection based on the ingredient list. 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).
This sunscreen is a mineral sunscreen. It uses titanium dioxide and zinc oxide for sun protection. Both titanium dioxide and zinc oxide almost never irritate even the most sensitive skin and eyes, but can leave a white cast.

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).
Three steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect
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.
Works as a UV filter when used in high concentrations. It is photostable and is effective mostly against the UVB light, with some protection in the UVA range. In small concentrations, used for its ability to improve the color of cosmetic products. Is usually well tolerated by the skin
A broad spectrum sunblock (protects from both UVA and UVB rays). Is suitable for most sensitive skins. In small concentrations, can be used as a colorant

A plant extract that can help neutralize free radicals in skin. It contains a compound salicin that can theoretically be converted into salicylic acid that, in turn, helps reduce inflammation in skin, but the evidence of effectiveness in skin is lacking and the extract is usually not used in a concentration that would enable an exfoliating effect
Being a lipid soluble form of vitamin C, it is more stable and can penetrate the skin better than L-Ascorbic acid. It is effective in protecting the skin from free radicals, as well as evening the skin tone, but is less effective in stimulating collagen production compared to L-Ascorbic acid.
