Vitamin A - Retinoid vs Retinol?
Vitamin A is a crucial nutrient for keeping our skin healthy, but our bodies can’t make it on their own. Instead, we get it from foods rich in beta carotene or from applying Vitamin A derivatives directly to the skin. In skincare, Vitamin A comes in two main forms: retinoids (from animal sources) and carotenoids (from plants). In this guide, we'll explore the amazing benefits of retinoids, the different types, and introduce the innovative Hydroxypinacolone Retinoate (HPR).
Retinoids have been shown time and again to be effective against signs of aging. They speed up skin cell turnover and help shed old, dead skin cells, which makes the outer layer of your skin look smoother and more refreshed. Plus, retinoids boost the production of glycosaminoglycans, which help keep the skin hydrated. They also support collagen production and get rid of damaged elastin fibers. Since collagen decreases as we age, retinoids help maintain skin firmness and elasticity, making your skin look younger.
Here are 3 key things that affect how well retinol and its derivatives work:
Prescription retinoids like Tretinoin, Adapalene, and Tazarotene are considered the gold standard and give excellent results. However, they can also cause side effects like irritation, redness, and peeling, which might not be ideal for sensitive skin.
Retinol is the most common form of Vitamin A in over-the-counter skincare products. Other forms include Retinyl Palmitate, Retinyl Acetate, and Retinyl Linoleate, but these need to be converted into retinoic acid to work effectively on your skin.
Here are 3 key things that affect how well retinol and its derivatives work:
- Conversion Steps: Retinol needs to go through two conversion steps (Retinol > Retinaldehyde > Retinoic Acid), while Retinyl Palmitate needs three (Retinyl Palmitate > Retinol > Retinaldehyde > Retinoic Acid). More conversion steps mean the retinoid is less potent.
- Stability: Vitamin A derivatives are naturally unstable and can break down when exposed to air and light, which can reduce their effectiveness over time.
- Concentration: The effectiveness of retinol depends on its concentration. Higher concentrations convert more efficiently to retinoic acid but can sometimes cause more skin irritation.

Hydroxypinacolone Retinoate (HPR) is a new, hybrid form of Vitamin A that combines elements of both retinol and retinoic acid. HPR doesn’t need conversion; it’s directly recognized by skin cells as retinoic acid, which makes it highly effective. It also has better stability and is gentler on the skin compared to other retinoids. While retinoids are powerful anti-aging tools, noticeable improvements usually take at least three months of consistent use.
