How to Use

• After cleansing (and toning, if you use one), apply a few drops to the face, avoiding the immediate eye area. Pat gently for better absorption. 

• In daytime, always follow with a broad-spectrum sunscreen when using any retinol product. 

• For sensitive or retinol‑naïve users, you may start using it every other night and gradually increase to nightly as tolerated. (Though some sellers recommend daily use with caution.) 

Suitability / Cautions

• Skin Types: Marketed as suitable for all skin types, including sensitive skin, because of its low-irritation approach. 

• Irritation Risk: Despite being “gentle,” some users report mild stinging, redness, or breakouts (especially in early use). 

• Patch Test Advised: As with any active, it’s wise to patch test on a small area before applying to the full face.

• Avoid Overuse of Other Actives: Be careful combining with strong acids, retinoids, or strong exfoliants until skin tolerance is built.

• Pregnancy / Breastfeeding Caution: Retinoids are generally discouraged during pregnancy/breastfeeding, so consult a medical professional before use.
