Product Summary
"The INKEY List CA - Retinol Serum" is effective for: Anti-aging, Evens skin tone, Anti-blemish and Moisturizing
Ingredient callouts
- this product contains an effective form of Retinoids (vitamin A): retinol 0.10% - 0.40% and hydroxypinacolone retinoate 0.05% - 0.10%. 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.
- Peptides (palmitoyl tripeptide-1 0.05% - 0.30% and palmitoyl tetrapeptide-7 0.10% - 0.35%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, but it is very likely that they have a benefit. They might help restore the skin barrier and fight the signs of aging. At the very least, Peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.
- Humectants (hyaluronic acid 0.10% - 0.35% and glycerin 3.90% - 5.90%). 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?
leaving skin brighter, smoother and more youthful-looking
Source: Cultbeauty
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains hydroxypinacolone retinoate, retinol.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: palmitoyl tetrapeptide-7.
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.
A derivative of the most potent form of vitamin A, retinoic acid. The ingredient can be sold under name Granactive Retinoid. Note that if a skincare brand discloses the concentration of Granactive Retinoid in a product, the concentration refers to a diluted form of Hydroxypinacolone Retinoate: 1% of Granactive Retinoid corresponds to 0.1% of Hydroxypinacolone Retinoate. Hydroxypinacolone Retinoate (HPR) is a unique derivative of retinoic acid because it can directly work in the skin and does not require additional conversion steps. According to studies done by the manufacturer on models of human skin (not real people), this derivative is more effective than other cosmetic versions of retinoids (such as retinol, retinaldehyde, and retinyl palmitate), and, at the same time, causes less irritation. It has been also demonstrated to be more stable than retinol which makes formulating with easier and increases the chances that a product with it will maintain its effectiveness after opening. The packaging should still ideally be air-tight. HPR is available over the counter in the EU, UK, Asia, Australia and New Zealand, but is only with a prescription in Canada.
Two 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

One of the best moisturizing ingredients. Attracts water into the upper layer of the skin. Naturally present in skin. Typically has large molecule size unless advertised otherwise on the product label. Helps support skin's barrier function and may help to reduce inflammation

Moisturizing
What does the product description say?
squalane for hydration and nourishment
Source: Cultbeauty
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, hyaluronic acid.
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, squalane.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: palmitoyl tetrapeptide-7
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
