“Reduces the appearance of sunspots, fine lines, and wrinkles”
Source: Cowshed

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

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.

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~0.35–0.85%

What the product description says
“The addition of Vitamin B5 provides deep moisture, leaving the skin more even, smooth, and youthful.”
Source: Cowshed

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": panthenol.

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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).

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

Lecithin· EmollientEffect: LowUsed mostly for creating emulsions - helping oil and water mix together. Helps soften the upper layer of the skin~0.55–1.3%

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