Note: Due to the high concentration of free acids, it‘s advisable for only experienced users with non-sensitive skin to apply this product. Contraindications: Avoid use on sensitive, flaky, or damaged skin. Refer to the Additional Sun Protection Note and other warnings detailed in the provided instructions. The formula’s pH is approximately 3.6. Glycolic acid, the main AHA used here, shares this acid dissociation constant of 3.6, crucial for assessing acid effectiveness. When the dissociation constant aligns closely with the pH, it creates an optimal balance between salt and acidity, enhancing the acid‘s efficacy while minimizing irritation. A higher pH might lead to excessive salt content, increasing potential irritation compared to a more acidic formulation. Note: While exfoliating acids can deliver immediate visual improvements, indirect peeling methods are generally recommended over direct methods like this solution due to risks of inflammation and sensitivity. Instructions for Use: 1. Cleanse and dry your face thoroughly. 2. Do not apply on wet skin. 3. With fingertips, distribute the product evenly across the face and neck, avoiding the eye area. 4.
