dry oil with retinol [SEP] i have used retinol products both otc and prescribed by my dermatologist i have been careful to only use retinol at night and to avoid direct sunlight after using retinol this serum does not specifically warn against going under direct sun but it is worth taking the precautioni liked the texture of the face oil retinol serum it feels like a dry oil and is easily absorbed into the skin it does not feel oily or sticky but it moisturizes it helps improve the firmness and tonei have sensitive skin and did not experience any redness irritation or sensitivity using this
