Take the skin test and I'll show you how suitable this product is for you.
Take the skin testFormulated with blemish-prone and oily skin types in mind, the La Roche-Posay Effaclar H Moisturising Cream for Sensitive Blemish-Prone Skin is a minimal ingredient, ultra-hydrating moisturiser. Cooling thermal spring waters are infused into the fine, creamy formula to help refresh lacklustre and fragile skin. The non-greasy texture absorbs quickly, while working to promote a soft complexion by creating a veil of moisture, to nourish even the most sensitive of skin types.
Effaclar H Iso-biome Soothing Moisturising Cream is a cushioning cream from La Roche-Posay, a brand based in France. The formula is built mainly around hydration and barrier support. The ingredient list runs to 24 ingredients, each broken down in full below.
By its ingredient list the formula reads as moderately cushioned — emollient enough to feel like a cream, without the heaviest occlusives near the top. Silicones in the formula tend to give a smooth, blurred finish and help it grip under makeup. Hydration is handled by Glycerin, Panthenol and Water, humectants that pull water into the upper layers of skin rather than sealing it there.
Hydration: High. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Glycerin, Panthenol, Water and Squalane.
Barrier support: High. Lipids and repair signals that support skin barrier integrity, and here that comes from Squalane, Panthenol and Niacinamide.
Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Panthenol and Niacinamide.
On richness alone it suits Balanced skin best, and is the least natural fit for Dry, Combination (dry), Combination (oily) and Oily skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.
The formula contributes little or nothing on antioxidant protection, cell renewal and firmness signalling. That is not a fault — most products are not meant to do everything — but if one of those is your priority, this is not the product that will address it. One ingredient on the label has not been matched to our database yet, so the analysis above reads a slightly incomplete list.
It can be used morning and evening. In a routine it goes after serums. Seal in your serums with it; in the morning, sunscreen still goes on top.
This summary is generated from the product's ingredient list. It is not a review, it is not the brand's own marketing claims, and it does not replace advice from a dermatologist.
Drawn purely from the ingredient list
Scored on how rich or light the formula reads from its INCI order.
No ingredient in this formula carries a common-irritant flag, making it a reasonable option for reactive skin. A patch test is still recommended, as individual skin reactivity varies.
Based on the curated benefits documented for this product's ingredients.
Attracts and locks in moisture to keep skin plump and dewy
Boosts collagen and cell turnover to reduce fine lines and wrinkles
Calms redness, irritation, and inflammation for sensitive skin
Regulates sebum production to reduce shine and greasiness
Tightens and refines the look of enlarged pores
None of the ingredients in this formula are associated with these benefits. This is not unusual, as most products are designed to target a limited number of concerns.
