Moisturizing
What does the product description say?
Skin is plumped, skin tone looks brigther and more even ; skin feels hydrated and energised.
Source: Ren Skincare
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, glycogen.
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: helianthus annuus seed oil, oryza sativa bran oil.
Helps to attract water to the upper layer of the skin
One of the best moisturizing ingredients. Attracts water into the upper layer of the skin
Yeast extract. Helps attract water to the upper layer of the skin
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
Helps attract water to the upper layer of the skin
A great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function
Helps soften the upper layer of the skin and might have some anti-oxidant properties
A plant extract that helps attract water to the upper layer of the skin. It might be helpful in neutralizing free radicals in skin, but is less potent than the extract from the seeds
Emollients that are naturaly present in skin. In addition, they help water and oil mix together in the product
A fruit extract that might help to attract water to the upper layer of the skin, but there is no evidence for any other benefits to the skin
An 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. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)
A vitamin C derivative. Studies show that is might be effective in reducing hyperpigmentation, but there are no studies confirming that it is effectively converted into the bioavailable form of Vitamin C in skin. It is not clear how this derivative compares in effectiveness to the topical application of bioavailable form of vitamin C (L-ascorbic acid)
Pure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself
Evens skin tone

This product contains ingredients (glycyrrhiza glabra root extract) that could help reduce hyperpigmentation (for example, post-acne marks or age spots) in theory, but there is not enough evidence that they actually work.

It is not clear how this derivative compares in effectiveness to the topical application of bioavailable form of vitamin C (L-ascorbic acid)
A derivative of vitamin C that is more stable, but less bioavailable than the pure form of vitamin C. It does not penetrate the skin well, but has been shown to convert to pure vitamin C once in skin. It can be helpful in stimulating collagen production and lightening the skin tone, but the required concentration is likely to be very high
Anti-aging
What does the product description say?
Glabridin, Tyrosinase Inhibitors and Vitamin C . Regulates skin pigmentation, reduces age spots and corrects skin tone.
