Apply a small amount to clean, dry skin on the face in the morning or evening. Dispense a pea-sized quantity and gently smooth and pat onto the skin; a slight gritty texture may be felt initially but will dissolve into the skin. A strong, temporary tingling sensation is expected and normal, particularly during the first few weeks of use. Start by using the product once daily and increase frequency gradually as your skin builds tolerance. Avoid the immediate eye area. Always use a broad-spectrum sunscreen during the day. Patch testing prior to first use is essential; this formula is not suitable for sensitive, compromised, or untrained skin.
