Retinol
Retinol is converted into its active form, retinoic acid, when it's absorbed by the skin. This conversion process involves several enzymatic steps. Retinoic acid is the form of vitamin A that directly interacts with the skin's receptors and influences cell turnover, collagen production, and other age-defying effects. While this conversion process makes retinol milder and less potent than prescription retinoids, it also results in a reduced risk of irritation, making it suitable for a broader range of users. Key when it comes to keeping skin in balance.* This is what we use in Age Rewind!
Retinyl Palmitate
Retinyl palmitate is a form of retinol ester. In skincare products, it needs to undergo a more extended conversion process to be transformed into active retinoic acid. This process involves the enzymatic breakdown of retinyl palmitate into retinol and then further into retinoic acid. As a result, products containing retinyl palmitate are typically milder and are often recommended for individuals with highly sensitive skin.
Retinaldehyde (Retinal)
Retinaldehyde, also known as retinal, is a closer relative to retinoic acid. When applied to the skin, it requires just one enzymatic conversion step to become retinoic acid. This makes retinaldehyde more potent than retinol and retinyl palmitate, offering faster and more visible results with potentially less irritation. It's often considered a bridge between OTC retinols and prescription retinoids.
Prescription Retinoids
Prescription-strength retinoids, such as tretinoin (Retin-A) and tazarotene, are already in the active retinoic acid form. They work directly with the skin's receptors and have the most potent effects. However, this potency comes with a higher likelihood of side effects, including redness, peeling, and increased sensitivity. These products require close supervision by a dermatologist.
