The Inkey List keeps the formula simple and the price low, which makes it a smart first bottle if you’re testing tolerance. Texture is light enough to layer under most moisturizers.

The Edyt Score
4.4 / 5.0
Targets
4.4/5
For testing retinol tolerance without a complicated bottle. Skip it if a retinoid is already in nightly use and working.
Formula standards
4.4/5
A light serum. Start slowly, and it can still flake if you stack acids the same night.
The verdict
A sensible first retinol. One 1-ounce bottle is enough to learn the skin's pace.
