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

This sunscreen uses organic (so-called "chemical") sunscreen filters. Organic, or "chemical" filters usually provide reliable sun protection and rarely leave a white cast. Sunscreens with organic filters can sting eyes.

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.

OctocryleneUVB Photo-stable A weak sunscreen that protects against the sun rays that cause sunburn (UVB) and is somewhat effective against the UVA rays. It is quite stable and can help stabilize other, more vulnerable, sunscreen ingredients like Avobenzone. It is an organic, or so called "chemical" sunscreen~4.1–6.1%

OctisalateEthylhexyl SalicylateUVBOctisalate. A UV filter. It offers some protection against the sun rays that cause sunburn (UVB), but does not protect against the most aging sun rays (UVA). It loses its effectiveness quickly when exposed to sunlight. It is an organic, or so called "chemical" sunscreen~1.3–1.9%

Uvinul TEthylhexyl TriazoneUVB Photo-stable Uvinul T. A UV filter. Effective against UVB rays. It is photostable. Can increase water resistance properties of the sunscreen. Unfortunately, not approved by the FDA (US) yet~0.6–1.4%

Butyloctyl SalicylateUVBA synthetic ester of salicylic acid that is used to help disperse pigments and boost effectiveness of sunscreen ingredients. It is able to absorb UV light (working as an organic, or chemical filter), but is not approved as a sunscreen ingredient on its own~0.15–0.55%

Tinosorb SBis-ethylhexyloxyphenol Methoxyphenyl TriazineUVBUVA Photo-stable Tinosorb S. One of the most effective broad spectrum sunscreen ingredients. Protects from both UVA and UVB rays. It is photostable. Approved by the US FDA in 2026 (listed as bemotrizinol on US labels).~0.45–1%

Evens skin tone

Not advertised by the brand · No ingredient credited for this claim

Works well

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).

Anti-aging

Not advertised by the brand · No ingredient credited for this claim

Works well

This product can 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.

Moisturizing

Not advertised by the brand · Caprylic/capric triglyceride, C12-15 alkyl benzoate + 4 more

Works

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: caprylic/capric triglyceride, c12-15 alkyl benzoate.

Keep in mind that this product does not contain effective ingredients to attract water to the upper layer of the skin. This is why an additional product with humectants like glycerin or hyaluronic acid can be helpful (apply it before this product for the best results).

Product summary

We believe that "ISDIN - Fotoprotector Transparent Spray Wet Skin SPF50" can provide reliable sun protection based on the ingredients listed. 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 contains good moisturizing ingredients and can double as a hydrating day cream. This product prevents early signs of aging by protecting against sun damage (all broad spectrum sunscreens do that).

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. The UV filters in this sunscreen are: tinosorb s 0.45% - 1.00%, avobenzone 2.10% - 3.10%, butyloctyl salicylate 0.15% - 0.55%, uvasorb heb 0.35% - 0.85%, uvinul t 0.60% - 1.40% and octocrylene 4.10% - 6.10%.
