Apply 2-3 drops to clean, dry skin in the evening, avoiding the eye area. Start with once weekly application, gradually increasing frequency as tolerance builds.

Q: Is 0.5% retinol much stronger than 0.1%? A: Yes, 0.5% is considerably more potent than 0.1%. This concentration is recommended for those who have already built tolerance to lower concentrations of retinol. Q: Why is this formulated as an oil? A: The oil delivery system helps stabilize the retinol while simultaneously providing nourishing benefits from plant oils that help minimize the dryness and irritation commonly associated with retinol. Q: How do I incorporate this into my routine? A: Use in the evening after water-based products but before or instead of moisturizer. Start with once weekly application, gradually increasing to 2-3 times weekly as tolerance builds. Always use SPF during daytime. Q: Will this cause more irritation than cream retinol products? A: While the percentage is higher (0.5%), the oil format helps buffer some irritation by providing nourishment. However, expect more potential for irritation than the 0.1% cream, especially during the initial adjustment period. Q: How should I store this product? A: Keep in a cool, dark place away from direct sunlight and heat to prevent degradation of the retinol. The dark glass packaging helps protect the formula, but proper storage extends efficacy.
