Ingredient callouts
- this product contains an effective form of Retinoids (vitamin A): retinol 0.30% - 0.60% and retinal 0.35% - 0.65%. 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 (sodium lactate 2.70% - 3.30%, sodium hyaluronate 0.25% - 0.40%, glycerin 3.30% - 4.00%, sodium pca 0.65% - 1.00% and galactoarabinan 2.20% - 2.70%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Anti-aging
What does the product description say?
Loaded with Vitamin E, this rapid renewal complex is the perfect way to introduce dry, sensitive skin to a Retinol product that traditionally cannot tolerate Retinol.
Source: Skinstore
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains retinal, 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.

It can, however, be irritating

Moisturizing
What does the product description say?
Nonirritating, hydrating formula normalizes skin and renews with amazing results.
Source: Skinstore
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:
galactoarabinan, 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: dimethicone, helianthus annuus seed oil.
