Sun protectionSPF 50 · 6 UV filtersBroad spectrum
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.
Anti-agingSodium ascorbyl phosphateWorks well
“UVA rays penetrate deep into the skin, causing long-term skin damage and premature ageing.”
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.
Evens skin toneSide benefit · No ingredient credited for this claimWorks 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).
MoisturizingSide benefit the brand mentions · C12-15 alkyl benzoate, Dimethicone + 8 moreWorks
“UVA rays penetrate deep into the skin, causing long-term skin damage and premature ageing.”
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, butylene glycol.
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: dimethicone, dimethiconol.

A 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 C

Product summary
We believe that "Soltan - Once Spray SPF50+" can provide reliable sun protection based on the ingredients listed. We love that it can protect from both UVA and UVB rays (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).
As a plus, this sunscreen uses some of the new generation UV filters (Tinosorb M). These filters are more stable and more gentle on the skin.
Because it includes good moisturizing ingredients, it can also work as a hydrating day cream. 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: tinosorb s 1.40% - 1.70%, avobenzone 3.50% - 4.20%, uvasorb heb 0.55% - 0.80%, octisalate 2.50% - 3.10%, tinosorb m 0.65% - 0.95% and octocrylene 4.40% - 5.40%.
Irritation risk
This formulation includes some common irritants, including ingredients that do not provide a benefit for the skin. We assess the overall irritancy of this sunscreen to be medium. For a detailed overview of all potential irritants: click here
