Skin

How it’s judged

Scored for skin — based on what its ingredients contribute.

What it may help with

UV protection i3.5 / 4

Whether it provides direct protection against UV radiation.

From Octocrylene, Ethylhexyl Salicylate, Butyl Methoxydibenzoylmethane, Homosalate

Hydration i3.5 / 4

Whether the ingredient helps increase the skin’s water content — humectants that attract water, ingredients that reduce water loss, or ones that make skin feel less dry.

From Glycerin, Sphingolipids, Biosaccharide Gum-2, Pentylene Glycol

Barrier support i3.5 / 4

Whether it supports the skin barrier — restoring lipids, reducing water loss, aiding barrier repair, or strengthening the skin’s protective function.

From Sphingolipids, Phospholipids, Glycerin, Tocopherol

Anti aging i3.0 / 4

Whether it can help visible signs of aging — fine lines, wrinkles, loss of firmness, or photoaging.

From ACETYL CARNOSINE, Tocopherol, Glycerin

Soothing i2.5 / 4

Whether it can calm the skin — linked to less redness, irritation, discomfort, or visible reactivity.

From Biosaccharide Gum-2, Magnesium Sulfate, Sphingolipids, Tocopherol

Things to watch

Endocrine i2.5 / 4

Whether it has known or suspected hormone-related activity or endocrine-disruption concern.

From Homosalate, Octocrylene

From Homosalate, Octocrylene

Sensitization i1.5 / 4

Risk of allergic contact dermatitis or immune-based reactions. Fragrance allergens, preservatives, botanicals, and some dyes may score here.

From Octocrylene, Chlorphenesin, Ethylhexyl Salicylate, Phenoxyethanol

Irritation i1.5 / 4

From Homosalate, Phenoxyethanol, Pentylene Glycol, Chlorphenesin

Eye irritation i1.5 / 4

Whether it may sting or irritate around the eyes. Relevant for sunscreens, fragrances, acids, surfactants, and volatile ingredients.

About this product

This product is a sunscreen serum formulated with a blend of chemical UV filters to provide broad-spectrum protection. It features a lightweight, serum-like texture, likely due to the presence of silicones and emollients. The formula also includes some antioxidant and skin-identical ingredients.

Good signs
  • Provides broad-spectrum UV protection with multiple chemical filters, offering good defense against UVA and UVB rays.
  • The serum texture is likely to be non-greasy and absorb well, making it suitable for daily use and potentially layering under makeup.
  • Includes antioxidants (Tocopherol, Acetyl Carnosine) which can help mitigate free radical damage caused by UV exposure.
  • Contains skin-identical ingredients (Phospholipids, Sphingolipids, Glycerin) that support skin barrier function and hydration.
  • The formula appears to be fragrance-free, reducing the risk of irritation for sensitive skin types.
  • The inclusion of Acetyl Carnosine suggests potential anti-aging benefits beyond UV protection.
Watch-outs
  • Contains multiple chemical UV filters, which some individuals with very sensitive or reactive skin might find irritating, although generally well-tolerated.
  • The presence of silicones (Dimethicone/Vinyl Dimethicone Crosspolymer) might not be preferred by all users, though they contribute to the product's texture and spreadability.
  • While offering hydration, it may not be sufficiently moisturizing for very dry skin types without an additional moisturizer.
Best for
  • Daily sun protection
  • Individuals seeking a lightweight sunscreen
  • Layering under makeup
  • Normal skin
  • Combination skin
  • Oily skin
  • Sensitive skin (patch testing recommended due to multiple chemical filters)
How to use it
  • Apply generously as the last step in a morning skincare routine, before makeup.
  • Reapply every two hours when exposed to direct sunlight, or after swimming/sweating.
  • Patch testing is advisable for individuals with known sensitivities to chemical sunscreens.
