Product summary

"La Roche-Posay - Effaclar Duo [+]" has a good moisturizing formula. As we expect from a proper moisturizer, the formula includes a combo of effective humectants and emollients. These are the two different types of ingredients that are essential for improving the skin hydration and supporting a healthy skin barrier. Glycerin, zinc pca and caprylyl glycol in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Emollients in this formulation (isocetyl stearate, dimethicone, isopropyl lauroyl sarcosinate, caprylyl glycol and isohexadecane) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.

Ingredient callouts

  • We love that this moisturizer contains a good concentration of niacinamide 2.00% - 3.10%. Niacinamide is a perfect active in a moistruizer because it helps calm down inflamation in skin and support the skin barrier. More than that, it is helpful for most common skin concerns: it helps regulat oil production, help reduce acne and clogged pores, improve skin tone and prevent pigmentation marks. It also helps fight photodamage.

Irritation risk

This formulation includes some common irritants, including ingredients that do not provide a benefit for the skin. We assess the overall irritancy of this moisturizer to be medium. For a detailed overview of all potential irritants: click here

WIMJ summary for anti-aging

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide.

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.

WIMJ summary for evens skin tone

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: capryloyl salicylic 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.

WIMJ summary for 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, zinc pca.

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: dimethicone, isocetyl stearate.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide

WIMJ summary for exfoliation

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: capryloyl salicylic acid.
