This product contains copper tripeptide-1. 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.

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

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.

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, aloe barbadensis leaf juice.

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: simmondsia chinensis seed oil.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: copper tripeptide-1

This product contains antioxidants (kojic acid) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
