Product claims breakdown

Anti-aging

BAKUCHIOL at ~1.7–2.6% + 1 more curated active

Strong evidence

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: carnosine.

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.

BAKUCHIOLRole: HeroA 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~1.7–2.6%

CARNOSINERole: Key activeA type of peptide. It attracts water to the upper layer of the skin. It can help neutralize free radicals in skin combatting the sun damage~0.4–0.9%

Caprylic/capric triglycerideRole: Key activeA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~2.9–4.4%

GlycerinRole: Key activeOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~2.2–3.3%

CaffeineRole: Key activeMight be helpful in neutralizing free radicals. Can have a dehydration effect that might somewhat decrease the look of puffy eyes~0.35–0.85%

PanthenolRole: Key activeHelps attract water to the upper layer of the skin and can help improve skin barrier function~0.3–0.7%

Sodium hyaluronateRole: Key activeOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.15–0.7%

Anti-oxidation

Quiet bonus

This product contains antioxidants (bakuchiol, carnosine) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

Moisturizing

Brand does not advertise this — the formula does

Quiet bonus

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: carnosine, glycerin.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: caprylic/capric triglyceride, dicaprylyl ether.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol
