What the product description says
“This clinically proven formula deeply hydrates, supports cell regeneration, boosts collagen production, smooths wrinkles, and firms the skin.”
Source: Sodashi

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains bakuchiol.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: centella asiatica leaf extract.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

Centella asiatica leaf extractKey activeEffect: MediumA plant extract that has been shown to be able to reduce inflammation in skin, support restoration of skin barrier function, as well as support collagen production. It can be irritating to sensitive skin. Might be helpful in preventing stretch marks. It could, however, itself be irritating.~0.95–1.4%
BakuchiolKey activeEffect: HighA 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~0.45–1.05%
TocopherolEffect: Low, below effective dosePure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.6–1.35%

What the product description says
“This clinically proven formula deeply hydrates, supports cell regeneration, boosts collagen production, smooths wrinkles, and firms the skin.”
Source: Sodashi

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: caprylic/capric triglyceride, helianthus annuus 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).

Evens skin tone
Side benefit · Bakuchiol
Works well

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: bakuchiol

Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.
