MoisturizingNiacinamide, Glycerin + 5 moreStrong evidence
“Mela B3 Dual Body Treatment visibly unifies and smooths skin, while providing all-day hydration.”
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, caprylyl glycol.
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: niacinamide
ExfoliationCapryloyl salicylic acidStrong evidence
“LHA: Also known as LHA, it's a derivative of salicylic acid, and has exfoliating and skin surface renewing properties.”
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: capryloyl salicylic acid.
Evens skin toneNiacinamide, Capryloyl salicylic acidStrong evidence
“MelasylTM and Niacinamide work together to help visibly correct even stubborn dark spots.”
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: capryloyl salicylic 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.
Anti-blemishNot advertised by the brand · Niacinamide, Capryloyl salicylic acidStrong evidence

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: capryloyl salicylic acid
Anti-agingNot advertised by the brand · Niacinamide, TocopherolStrong evidence
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide.
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.
