Product summary
What can the product work for?
Anti-blemish
retinol
0.55% -
1.3%
Irritation risk:
Concentration: Effectiveness: HIGH
Two steps removed from the active form of vitamin A - retinoic acid. Once converted to the retinoic acid in the skin, retinol is proven to be effective against all signs of aging. It improves skin cell turnover, helps fight blemishes and clogged pores, can regulate excess oil production and even skin tone. It can, however, be quite irritating
niacinamide
1.4% -
2.1%
Irritation risk:
Concentration: Effectiveness: HIGH
Is proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture.
The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production
bakuchiol
2% -
3%
Irritation risk:
Concentration: Effectiveness: HIGH
A plant extract that is, though different in chemical structure, acts similar to retinoids. First studies show that it can help reduce fine lines and wrinkles, improve skin tone, reduce clogged pores and blemishes, and reduce inflammation. There is no conclusive evidence that bakuchiol is as effective as retinol however. The study that directly compared retinol with bakuchiol used bakuchiol applied twice daily compared to once per day for the retinol. According to this study, bakuchiol is less irritating than retinol. Bakuchiol is extracted from seeds of Babchi plant. Other parts of the plant contain coumarins that could cause allergic and irritant reactions. These compounds should be removed in the extraction process when bakuchiol is produced, but it is a good idea to be cautious and stay away from products that include the Babchi plant extracts other than purified bakuchiol to avoid irritation

rosa damascena extract

Irritation risk:
Oil of a very fragrant pink rose used as fragrance in cosmetics. Extensive research has shown it has mixed benefits. In the pro column, inhaling this flower’s scent seems to have relaxing properties and the plant’s petals contain skin-soothing and antioxidant compounds that can benefit skin. On the flipside, the numerous chemicals that create this rose’s distinctive fragrance pose a risk of causing skin aggravation.
