Product Summary
"Erno Laszlo - Brightening Dual Phase Peel Duo" could be helpful for: Moisturizing, but its actives are not the most effective or are not well-studied.
Ingredient callouts
- Humectants (glycerin 0.40% - 0.90%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
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, butylene glycol.
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, caprylyl glycol.
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
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 preserve products and creates a nice product texture
Used to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin
Used to create a nice product consistency
An emollient that softens the skin and forms a protective layer on its surface. Helps water and oil mix together
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)
Exfoliation

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
