Retinol products for sensitive skin
The products with high concentrations do exist but may still not deliver the purported benefits for a number of reasons. In particular, a product with highly concentrated retinol may cause skin irritation, especially in people with sensitive skin. Highly concentrated retinyl palmitate is less irritating than retinol (at equivalent levels) but is also less effective. (After all retinyl palmitate is the farthest away from retinoic acid in the metabolic pathway.) Furthermore, conversion rates of various forms of vitamin A to retinoic acid vary among individuals - the same product/concentration may yield visible benefits in some people and little or none. Further still, retinol, and to a lesser degree retinyl palmitate, can be degraded by oxidation if formulated, stored and/or used improperly. Considering all these caveats, how should one use retinol / retinyl palmitate products (if at all)?cell to boost retinoic acid levels and produce clinically meaningful effects. Numerous products with retinol and retinyl palmitate are touted as equivalent to retinoic acid (tretinoin, retin A) in effectiveness yet devoid of its side effects. The reality is a bit more complicated. Many of these products contain too little retinol / retinyl palmitate to have any noticeable effect. Simply the fact that these agents are in the list of ingredients is not enough.
Only retinoic acid and its analogs collectively called retinoids have direct effect on skin cells and can adjust their physiology toward a shirt more youthful state. In fact, retinoic acid. Tretinoin is the active ingredient in Retin a and Renova - some of the best-known anti-wrinkle creams (see our article on tretinoin ). However, topical retinoic acid often causes skin irritation and other side effects, which limit its use, especially in sensitive individuals. The good news is that skin cells have the "equipment" (specialized enzymes) converting various forms of vitamin a into retinoic acid. Indeed, if sufficient amounts of retinol, retinyl palmitate or retinaldehyde are added to the culture of skin cells, the amount of retinoic acid in the cells increases. Therefore, at least in theory, topical vitamin A may deliver at least some of the well-established skin benefits of retinoic acid while producing fewer side effects. Not all forms of vitamin a are created equal. Some are more easily converted to retinoic acid than others. A typical conversion pathway looks like this: Retinyl palmitate retinol retinaldehyde retinoic acid. It takes two and three metabolic steps, correspondingly, to convert retinol and retinyl palmitate to retinoic acid.

Retinol and retinyl palmitate are among the most widely used active ingredients in skin care products. Unfortunately, there is much confusion about how they work, what results they can deliver and what their manicure optimal usage. This article will help clarify these issues. First, let me explain the basics. Both retinol and retinyl palmitate are forms of vitamin A (along with yet another form retinaldehyde). As opposed to many other vitamins, vitamin A does not have much of a direct biological effect. It works via its active metabolite (biochemical derivative) called retinoic acid.
