“Speeds up cell-turnover and promoting collagen production.While erasing lines, it shrinks open pores, and reduces acne scars.”
Source: Bluemercury

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

Hydroxypinacolone retinoateHeroEffect: HighA 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.~0.15–0.55%
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~1.6–2.3%
Lactic acidUnder-dosedEffect: HighAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles.

Source: Bluemercury

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

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.

Moisturizing

Good support

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: caprylic/capric triglyceride, cocos nucifera oil.
