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: butyrospermum parkii butter, caprylic/capric triglyceride.

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

Evens skin tone
Retinol, Glutathione + 2 more
Works well
What the product description says
“Skin will appear smoother while hyperpigmentation is reduced.”
Source: Escentual

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 glutathione. This ingredient (ingredients) might help reduce hyperpigmentation, but the effect, if any, is likely to be small.

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~0.2–0.4%
GlutathioneKey activeEffect: HighA peptide that can help neutralize free radicals in skin and reduce melanin production resulting in skin lightening effect and reduction in hyperpigmentation. It can also help attract moisture to the upper layer of the skin~0.15–0.3%

3-o-ethyl ascorbic acidUnder-dosedA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help 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~0.2–0.35%

What the product description says
“Perfect for first-time retinol users, The Retinol 0.1 Cream is formulated to prevent and correct early signs of aging before they set in.”
Source: Soko Glam

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

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

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.

Exfoliation
Side benefit · Retinol, Allantoin

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.

Product summary

Judging from the ingredient list, "COSRX - The Retinol 0.1 Cream" works well for improving skin hydration As we expect from a proper moisturizer, the formula includes a combo of effective humectants and emollients. These are the two different types of ingredients that are essential for improving the skin hydration and supporting a healthy skin barrier. Panthenol, glycerin, hyaluronic acid, hydrolyzed hyaluronic acid and sodium acetylated hyaluronate in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Glycine soja oil, butyrospermum parkii butter, caprylic/capric triglyceride, dimethicone and helianthus annuus seed oil in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.

Ingredient callouts

  • This product also contains Vitamin C (Ascorbic Acid). It can be an effective active for anti-aging and evening out the skin tone, but in this moisturizer it is used for stabilizing other ingredients in the formulation. In this concentration (0.20% - 0.35%) it cannot have a noticeable benefit for the skin.
  • This moisturizer contains an effective form of Retinoids (vitamin A): retinol 0.20% - 0.40%. 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. Because of the irritation risk of Retinoids, we recommend to have another, retinoid-free moisturizer in your routine to use on the alternate days or when your skin feels dry.
  • Adenosine 0.20% - 0.40%. It is a compound that in involved in many biological processes inside the skin cells. According one high-quality clinical trial, topical Adenosine in low concentrations can somewhat help improve "deep wrinkles" - the wrinkles that appear with age in places where our faces are most dynamic (for example, on the forehead or in the corners of the eyes).
  • An effective concentration of Panthenol (pro-vitamin B5) - about 1.30% - 1.60%. Panthenol helps strengthen the skin barrier, improve hydration and reduce inflammation in skin.
This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: vitamin c, stearic acid, allantoin and vitamin e
