Review title is Dry oil with retinol [SEP] I've used retinol products, both OTC and prescribed by my dermatologist.  I've 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 precaution.<br /><br />I liked the texture of the Face Oil Retinol Serum - it feels like a dry oil and is easily absorbed into the skin. It doesn't feel oily or sticky but it moisturizes. It helps improve the firmness and tone.<br /><br />I have sensitive skin and did not experience any redness, irritation, or sensitivity using this.
