![]() This may be due in part to its exfoliating, which removes debris that may stretch your pores open. Vitamin A is a powerful antioxidant that helps repair damaged skin, boost collagen to reduce fine lines, and speed cell turnover to even out discoloration and smooth the skin. Your pore size is set by your genetics, but retinoids such as retinol can help improve your pore’s shape and size, according to Begoun*. When considering a Vitamin A Skincare, it is worth considering the type of ingredient being used and its strength. ![]() Even though some skin care products are labelled as “retinol”, there actually only contain retinyl palmitate as an active ingredient and no actual retinol ingredient.Ĭosmeseucital brands more commonly contain Retinol and Retinal as well as having the correct delivery systems to drive them into the deeper layers of the skin. Over the counter brands tend to contain the lowest form Retinyl Palmiate. Retinaldehyde (or retinal, vitamin A aldehyde).Tretinoin – Available through a precription from a ZO Stockist.Isotretinoin / Tazarotene – Prescription only.Below indicates starting with the strongest and working down to the weakness this degree of Retinoid strength: Retinyl palmitate, retinol, retinaldehyde, adapalene, tretinoin, isotretinoin, and tazarotene are the different forms. There are in fact various forms of Vitamin A, all carrying a degree of variation in the strength. Retinol is a form of Vitamin A and seems to be more commonly known than the other types. But what is a Retinol and how does it work? What is Retinol? Ranella Hirsch, M.D., president-elect of the American Society of Dermatologic Surgeons, who said, “We have beautiful, profound data that shows if you use for 20 years, you’re going to look a lot better than someone who doesn’t.” It is clear to see why. It's a nice one to spot on the ingredient list pretty much for any skin type.When we start looking at anti-ageing skincare, Vitamin A or Retinols seem to be a predominant reoccurring theme. 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. As for linoleic acid and the skin, LA is a really important little guy found naturally in our skin.
