Retinoids Explained
Decoding the Retinoid Family
Retinol, retinal, or retinoic acid? Here is how to pick your strength and start your journey without the dreaded irritation.
The retinoid world is confusing, but it boils down to how many steps your skin needs to convert the ingredient into active retinoic acid. Think of it like a relay race where the finish line is the same, but the starting point varies.
The Conversion Chain
- Retinol: Requires two conversion steps; generally gentler and widely available.
- Retinaldehyde: Only one step away from the active form; often faster acting than retinol.
- Adapalene: A synthetic retinoid specifically studied for acne-prone skin.
Starting Out
If you are new to the game, start with a low-concentration retinol twice a week. You want to build tolerance, not a damaged barrier. If your skin feels tight or peels, pull back. Consistency beats intensity every single time. Once your skin is happy, you can slowly increase the frequency to nightly use. Always wear sunscreen the next morning, as these actives make your skin more sensitive to UV light.
Start slow and stay consistent; the best retinoid is the one your skin can actually tolerate.
