After cleansing and applying your eye cream, take 1-2 pumps of the resurfacing retinol serum and gently massage it onto your face and neck. Follow this with a hydrating serum and moisturiser.For those with oily, combination, or mild acne-prone skin types, incorporate the serum into your routine 1-2 times daily, in the morning and/or evening. If you have normal, sensitive, or dry skin, use the serum once daily at night or every other night. Always ensure to apply a sunscreen during the day when using this product.If you're new to retinol, start by applying the serum a few times a week at night. Gradually increase the frequency to daily use to allow your skin to acclimate.
