The BeautyBrains blog made a fantastic article about ceramides and they have listed a couple of examples about studies showing that ceramides - especially when used in certain ratios with cholesterol and fatty acids - do hydrate the skin and can help to repair the skin barrier. Now the question is only this: If we put ceramides all over our face do they work as well as ceramides already naturally in our skin? Well, the answer is probably a no, but they do work to some extent. So ceramides form kind of a "water-proof" protecting layer and make sure that our skin remains nice and hydrated. If ceramides in the skin are decreased, more water can evaporate from the skin and there is less water remaining in the skin. Ok, so now we know what ceramides are, let's see what they do in our skin: research shows clearly that they play a super important role in keeping the skin barrier healthy and the skin hydrated.
It's a nice one to spot on the ingredient list pretty much for any skin type. Overall, linoleic acid is a multi-functional skin goodie with barrier repairing, acne-reducing, and skin-lightening magic abilities. It lightens hyperpigmentation (aka UVB caused sun spots) both by blocking the melanin production of melanocytes (the skin cells that make the pigment melanin) and by enhancing the desquamation of melanin pigment from the upper layers of the skin. If that was not enough, we have one more thing to report about LA. A double-blind study using a 2.5% LA gel for 4 weeks found a 25% reduction in the size of microcomedones, the tiny blocked pores that can later lead to acne. So LA-deficiency in the skin seems to be connected not only to an impaired skin barrier but also to acne and smearing LA all over your face might help with your problem skin. Research shows that problem skin has lower levels of linoleic acid (and higher levels of oleic acid) than normal skin. LA is not only important for dry, barrier damaged skin types but also for acne-prone skin. LA deficiency leads to an impaired more permeable skin barrier and the topical application of LA-rich sunflower oil can fix this issue rapidly (while oleic-rich olive oil did not have the same barrier repairing effect). Knowing this, it will not come as a surprise that Linoleic acid has a central role in the structure and function of stratum corneum permeability, aka healthy skin barrier. It is the most abundant fatty acid in the epidermis and it serves as a structural precursor for important skin lipids called ceramides. Lauryl PEG-9 Polydimethylsiloxyethyl Dimethiconeĭimethicone/Vinyl Dimethicone CrosspolymerĪs for linoleic acid and the skin, LA is a really important little guy found naturally in our skin.
