Sun protectionSPF 40 · 3 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.
MoisturizingCeramide ng, Palmitoyl hexapeptide-12 + 13 moreStrong evidence
“What it is: A clean, silicone-free, comfy mineral sunscreen packed with ceramides and peptides to moisturize, visibly smooth and brighten, and create the dreamiest makeup base.”
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:
allantoin, fructooligosaccharides.
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: caprylic/capric triglyceride, c12-15 alkyl benzoate.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: ceramide ng, palmitoyl hexapeptide-12
Anti-agingPalmitoyl hexapeptide-12, Lactic acidStrong evidence
“It visibly brightens, defends against signs of aging, and hydrates and soothes for softer, more supple skin.”
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains palmitoyl hexapeptide-12.
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.
Evens skin toneNot advertised by the brand · Lactic acidStrong evidence
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).

Product summary
The ingredient list suggests that "Kosas - DreamBeam Silicone-Free Mineral Sunscreen SPF 40 with Ceramides and Peptides" can provide reliable sun protection. 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).
It also works as a moisturizer, so you do not have to use an additional hydrating product. Like all broad-spectrum sunscreens, this product helps prevent early signs of aging.
Sunscreen filters
This sunscreen uses a mixture of both mineral and organic (so-called "chemical") UV filters. The organic filters in the product are: butyloctyl salicylate. As for the mineral filters, this sunscreen uses zinc oxide.
Irritation risk
