What the product description says
“Promotes exfoliation to eliminate uneven skin tone and improve skin smoothness”
Source: Zo Skin Health

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: retinol.

Acetyl glucosamineKey activeEffect: MediumAn effective moisturizing ingredient that also has been shown to be effective in evening out the skin tone and reducing hyperpigmentation. It can help somewhat reduce wrinkles in skin~0.3–0.6%
RetinolKey activeEffect: HighTwo steps removed from the active form of vitamin A - retinoic acid. Once converted to the retinoic acid in the skin, retinol 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. It can, however, be quite irritating~0.25–0.45%
GluconolactoneUnder-dosedA polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals~0.2–0.4%

What the product description says
“A retinol-based solution clinically proven to rapidly improve the appearance of uneven skin tone for a brighter, clearer and smoother complexion.”

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

In addition, this product contains acetyl glucosamine, bakuchiol, glutathione. 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: ascorbyl glucoside.

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.

Has a potential to boost collagen production, nutralise free radicals and reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products~1.2–1.5%
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~0.4–0.65%

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: ascorbyl glucoside.

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.

What the product description says
“Improves skin texture + dryness and eliminates visible discoloration for brighter + smoother looking skin”
Source: Zo Skin Health

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: glycerin, caprylyl glycol.

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: dimethicone, cetearyl alcohol.

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

A polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals

Product summary

"ZO Skin Health - Retinol Skin Brightener 1%" is effective for: Anti-blemish, Moisturizing, Exfoliation, Anti-aging and Evens skin tone

Ingredient callouts

  • this product contains an effective form of Retinoids (vitamin A): retinol 0.50% - 0.75%. Retinoids are potent multitasking actives. They work to improve and prevent early signs of aging, reduce hyperpigmentation (age spots and post-acne marks), and prevent inflamed blemishes and clogged pores. The downside of Retinoids is that they can be irritating. If you are not already using a Retinoid in your routine, it is best to start slowly and apply the Retinoid product only a few times per week. If your skin tolerates it well, you can gradually increase the frequency to daily.
  • Humectants (acetyl glucosamine 0.40% - 0.65% and glycerin 3.10% - 3.70%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Price

The product retails from 64.66$ up to 130.00$ in the United States and for 124.99£ in the United Kingdom.
