This product can help soften the skin and reduce its moisture loss with emollients and occlusives: butyrospermum parkii butter, simmondsia chinensis seed 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).

What the product description says

“Rich in essential fatty acids and natural antioxidants, the plant-based elixir penetrates deeply and absorbs quickly without greasy residue; it supports the skin's barrier function, whilst minimizing the appearance of fine lines and wrinkles.”

Source: SkincareRX

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 - butyrospermum parkii butter - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.
