Product Summary
"Kri Skincare - Renew Exfoliate Serum" is effective for: Evens skin tone, Exfoliation and Anti-aging
This product could be helpful for: Moisturizing, but its actives are not the most effective or are not well-studied.
Ingredient callouts
- This product contains acids (gluconolactone 2.00% - 2.90%). Their concentration is low, and they will not have a strong exfoliating effect. Instead, they work to support the skin natural acid mantle and to attract water (as humectants). PHAs (gluconolactone) especially are great for improving skin hydration. They might be even able to stimulate the production of skin's natural humectants and support the healthy skin microbiome.
- Humectants (sodium hyaluronate 0.40% - 0.90% and glycerin 4.00% - 6.00%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Works for
Does not work for
Anti-aging
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains gluconolactone.
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.
A polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals
Evens skin tone
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: gluconolactone
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.

Exfoliation
What does the product description say?
Renew Exfoliate Serum
Source: From product name
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: gluconolactone.

Anti-oxidation
This product contains antioxidants (gluconolactone) 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.

Moisturizing
What does the product description say?
It also softens, hydrates and locks in moisture.
Source: Kri Skincare
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, sodium hyaluronate.
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).

Featuring natural fruit acids that resurface and refine the skin, this serum reduces congestion and the appearance of pores.

This product contains ingredients (gluconolactone) that could help reduce blemishes and clogged pores in theory, but there is not enough evidence that they actually work.
