UVA I protection: UVA II protection: UVB protection: Photo stable: Ingredient type Organic
A 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
Anti-aging
What does the product description say?
Vitamin A boosts the production of collagen to alleviate skin damage that aging has caused, while vitamin C enhances your natural beauty by brightening dark spots to even your skin tone.
ascorbic acid
0.25% -
0.45%
Irritation risk:
Concentration: Insufficient!
The most well-researched antioxidant that works in skin. Helps neutralize free radicals supporting collagen production, helping to even out the skin tone and preventing early signs of aging
gluconolactone
0.45% -
0.65%
Irritation risk:
Concentration: Insufficient!
A polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals
retinyl palmitate
0.25% -
0.4%
Irritation risk:
Concentration: Insufficient!
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
