General, ingredient-based — not your personalized match.
See how this fits your skin
Take the skin test and I'll show you how suitable this product is for you.
Take the skin testDiscover La Mer The Concentrate, a potent barrier serum for skin that feels stronger, more stable, and calmer. Each day, exposure to environmental stressors can cause irritation—a root cause of visible signs of premature skin ageing. With barrier-strengthening benefits and antioxidant and barrier protection, The Concentrate is your double source of strength against these daily irritants. Infused with Concentrated Miracle Broth™, a super-potent form of powerhouse elixir, the formula helps reduce the appearance of irritation and helps calm the look of skin so it can focus on natural renewal. Skin emerges feeling stronger, more stable and calmer.
The Concentrate is a cushioning serum from LA MER. The formula is built mainly around hydration and soothing. The ingredient list runs to 49 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, Cyclopentasiloxane and Algae Extract, humectants that pull water into the upper layers of skin rather than sealing it there.
Hydration: Very high. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Glycerin, Cyclopentasiloxane, Algae Extract and Dimethicone.
Soothing: High. Ingredients aimed at visible redness and reactivity, and here that comes from Isononyl Isononanoate, Algae Extract, Laminaria Ochroleuca Extract and Chlorella Vulgaris Extract.
On richness alone it suits Balanced skin best, and is the least natural fit for Combination (oily) and Oily skin. Several ingredients carry irritation flags. If your skin is reactive, this is one to patch test carefully or approach slowly.
The formula contributes little or nothing on antioxidant protection, oil control, brightening and tone and cell renewal. 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.
Reading the full list, the formula is paraben-free, microplastic-free, sulfate-free, dye-free, oil-free and no animal-derived ingredients. Those claims come from the ingredient list itself, not from the packaging. It does contain fragrance, essential oils and drying alcohol, worth knowing if your skin reacts to any of them.
It can be used morning and evening. In a routine it goes after toner, before moisturiser. Apply to clean, dry skin and give it a minute to absorb before the next layer. Introduce one new treatment at a time so you can identify what is working.
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.
