“Effaclar H Iso-Biome Moisturising Cream for Sensitive, Blemish Prone Skin”
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, caprylyl 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: myristyl myristate, squalane.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide
Evens skin toneNot advertised by the brand · 1 ingredient credited for this claimStrong support
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide
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.
Anti-agingNot advertised by the brand · 1 ingredient credited for this claimStrong support
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.
Anti-blemishNot advertised by the brand · 1 ingredient credited for this claimStrong support
This product can help reduce breakouts and clogged pores because it contains the following ingredient: niacinamide. This ingredient is used for treating acne and can have a noticeable effect.

Product summary
Based on the ingredient list, "La Roche-Posay - Effaclar H Iso-Biome Moisturising Cream for Sensitive, Blemish Prone Skin" can work well for skin moisturization. The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Glycerin 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). Myristyl myristate, squalane, caprylyl glycol, palmitic acid and stearic acid in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.
Ingredient callouts
- We love that this moisturizer contains a good concentration of niacinamide 2.30% - 2.80%. 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.
