Key actives
Product Summary
"Earth Rhythm - 10% VITAMIN C FACE SERUM" could be helpful for: Moisturizing and Evens skin tone, but its actives are not the most effective or are not well-studied.
Ingredient callouts
- Humectants (sodium hyaluronate crosspolymer 0.90% - 1.35%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
Anti-oxidation
This product contains antioxidants (3-o-ethyl ascorbic acid) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
A vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products

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