What the product description says
“Helps improve the appearance of skin’s brightness and provides a more even skin tone”
Source: Zo Skin Health

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

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.

RetinolHeroEffect: 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~1.4–2%
Ascorbic acidUnder-dosedThe most well-researched antioxidant that works in skin. Helps neutralize free radicals supporting collagen production, helping to even out the skin tone and preventing early signs of aging~0.2–0.7%

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

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 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.

What the product description says
“Formulated with 1% retinol to improve skin texture and uneven pigmentation, and to minimize the appearance of fine lines and wrinkles.”
Source: Face the future

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, helianthus annuus seed oil.

CyclopentasiloxaneKey active· EmollientEffect: MediumA silicone that helps improve the product texture and spreadability. Can absorb oil creating a short-term mattifying effect on the skin~23–35%
Dimethicone crosspolymerKey activeEffect: MediumUsed to create a thicker product texture. Helps soften the upper layer of the skin and might be able to prevent moisture loss from its surface~6.2–9.3%

This product could be helpful for: Moisturizing, but its actives are not the most effective or are not well-studied.

Ingredient callouts

  • this product contains Bakuchiol (0.35% - 0.85%). It is a plant extract that is has a similar effect to that of Retinoids but with less irritation. Bakuchiol can help reduce fine lines and wrinkles, improve skin tone, reduce clogged pores and blemishes, and reduce inflammation.
  • This product contains an effective form of Retinoids (vitamin A): retinol 2.10% - 3.20%. 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 (glycerin 3.60% - 5.40%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Price

The product retails for 318.67A$ in Australia, from 143.95$ up to 175.00$ in the United States and for 129.99£ in the United Kingdom.
