What the product description says
“A decadent cream formula created for experienced retinoid users and developed by dermatologic surgeon Dr. Antony Nakhla to promote collagen production and effectively target the appearance of fine lines, wrinkles and dark spots while refining pores and smoothing uneven skin texture.”
Source: Eighth Day

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

In addition, this product contains bakuchiol. This ingredient (ingredients) might help reduce hyperpigmentation, but the effect, if any, is likely to be small.

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: alanine.

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.

RetinalHeroEffect: HighOne step removed from the biologically active in skin form of vitamin A. Once converted to the retinoic acid in the skin, retinal 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. Concentrations of 0.05% and 0.1% are shown to be effective. It can, however, be irritating~0.2–0.4%
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~0.25–0.45%
AlanineEffect: LowAn amino-acid that helps to attract water to the upper layer of the skin and might help to lighten the skin, but solid evidence is lacking~0.2–0.4%
TaurineEffect: LowCould be helpful in reducing inflammation in skin, evening out the skin tone and neutralizing free radicals, but more research is needed to confirm its effectiveness~0.25–0.4%

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: acetyl hexapeptide-8, acetyl zingerone, palmitoyl tetrapeptide-7, palmitoyl tripeptide-5, serine, sh-oligopeptide-1, sh-oligopeptide-2, sh-polypeptide-1, sh-polypeptide-11, sh-polypeptide-9, threonine.

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.

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: alanine, arginine.

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: arginine, butyrospermum parkii butter.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8, palmitoyl tetrapeptide-7, palmitoyl tripeptide-5, panthenol, sh-oligopeptide-1, sh-oligopeptide-2, sh-polypeptide-1, sh-polypeptide-11, sh-polypeptide-9

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
