Product Summary
"goop Beauty - Dark Spot Exfoliating Sleep Milk Sérum Exfoliant de Nuit" is effective for: Exfoliation, Evens skin tone 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
- Exfoliating acids (lactic acid 1.40% - 1.70% and glycolic acid 4.40% - 5.40%). In this concentration, they will have a noticeable exfoliating effect. They can also have an anti-aging effect and stimulate collagen production in a long-run. PHAs (gluconolactone 1.60% - 2.00%) in this product also work 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 (polyglutamic acid 0.30% - 0.55%, sodium hyaluronate 0.45% - 0.65% and glycerin 1.20% - 1.50%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Anti-aging
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains gluconolactone, glycolic acid.
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
An alpha-hydroxy acid (AHA) that helps to remove the dead skin cells on the surface of the skin reveling a more even, smoother complexation. It is also able to stimulate collagen production with long-term use. Could help to reduce pore congestion. It can be irritating to the skin. Apply sunscreen daily if using products with glycolic acid
Might be helpful in restoring skin barrier function and, when combined with zinc carbonate and malonic acid, reducing fine lines and wrinkles by stimulating elastin production. Also helps stabilize the product formulation
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)
Traditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin
Evens skin tone
What does the product description say?
Dark Spot Exfoliating Sleep Milk Sérum Exfoliant de Nuit
Source: From product name
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: gluconolactone, glycolic 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.

Exfoliation

Dark Spot Exfoliating Sleep Milk Sérum Exfoliant de Nuit
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, glycolic acid.

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.

A plant extract that can be irritating. It might contain a compound anthocyanin that could be helpful in neutralizing free radicals
Moisturizing
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, polyglutamic acid.
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, squalane.
