MoisturizingPrunus armeniaca kernel oil, Rosa canina fruit oil + 5 moreGood evidence
“Increases moisture retention and boosts radiance .”
This product can help soften the skin and reduce its moisture loss with emollients and occlusives: simmondsia chinensis seed oil, prunus armeniaca kernel oil.
Keep in mind that this product does not contain effective ingredients to attract water to the upper layer of the skin. This is why an additional product with humectants like glycerin or hyaluronic acid can be helpful (apply it before this product for the best results).
Anti-agingDipalmitoyl hydroxyproline, Prunus amygdalus dulcis oil + 1 moreLimited evidence
“Provides yoour first line in defense against aging .”
This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.This ingredient - dipalmitoyl hydroxyproline - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.
