Best product for sensitive skin , unwrinkled skin – If you have sensitive skin and no wrinkles, the Lactic, glycolic, and Salicylic acids will work best for you. Its important to test before using because each person’s skin is different, so some people can leave the peel on for 5 minutes, while other people can only stand 30 seconds. For acne, salicylic acid has several properties that make it a very effective treatment for sensitive skin. It acts as an anti-inflammatory to help immediately reduce the inflammation of the acne. Also, the salicylic acid is oil soluble so it can penetrate the sebum clogged pores better than glycolic acid or lactic acid, which are both water soluble. Salicylic is relatively gentle and a great exfoliator. Also, the salicylic peel has little risk of complication because of the nature of the molecule. Salicylic acid is oil soluble, which is great for two reasons. First, the outside layer of you skin is covered in oil, meaning that the oil-soluble salicylic molecule is able to penetrate this outer layer. However the under this outermost layer is the dermis, and this layer is made up of mostly water. As you know oil and water don’t mix, and this keeps the salicylic acid from moving down past the outer most levels of the epidermis. What You Should Know of course nothing is without a downside, and Salicylic acid’s is that it can be very drying to the skin. Also, because it works at the surface of the skin it does not work as well at fading pigmentation beneath the epidermis as the Glycolic or the Lactic. So if you’re using it on a regular basis you need to apply a noncomedonic moisturizer like cetaphil to prevent excessive dryness. It is also very effective to combine the Lactic acid and salicylic acid treatments because lactic acid it is a natural humectant and actually pulls moisture into the skin. By alternating between the peels you get the benefits of the salicylic without the excessive dryness. If alternating, apply them 3-4 days apart, depending on your skin’s sensitivity. If you are looking more for a maintenance peel, any of our level 1 peels will be best for starting out and are mild enough for sensitive skin types.
