What the product description says
“Soften appearance of wrinkles .”
Source: Feelunique

This product contains retinyl palmitate. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

Retinyl palmitateKey activeEffect: MediumThree steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect~1.2–1.8%

What the product description says
“Soften appearance of wrinkles .”
Source: Feelunique

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.

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: ricinus communis seed oil, argania spinosa kernel oil.

Product summary

"Oh K! - Sleep Tight Face Patches x1" could be helpful for: Anti-aging, Moisturizing and Evens skin tone, but its actives are not the most effective or are not well-studied.

Ingredient callouts

  • this product includes a form of Retinoids (vitamin A) - retinyl palmitate 1.20% - 1.80%, but this type of vitamin A is not very effective. It could in theory help with fine lines and wrinkles, but the effect is most likely minimal.
  • Humectants (glycerin 4.10% - 6.10%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
