Tightening Skin (TSP) is a treatment for acne and dry skin. It is a product with a lot of hype, but doesn't have any scientific evidence that says it works for everyone. TSP is supposed to tighten the skin and make it less sensitive to the sun, but what do you think really works for you? Tightening Skin is not a product for everyone, but if you have sensitive skin, it may help. How To Apply Tightening Skin: I would say you apply a small amount of the product (about 1/4 of a teaspoon), then moisturize your face and neck with a moisturizer, moisturizer and sunscreen. After applying Tightening Skin, put on some sunscreen, then you can apply more Tightening Skin for your skin. You will need a cotton pad or cotton swab to apply the Tightening Skin product. You may use Tightening Skin over your regular moisturizer to make your skin a lot tighter and more hydrated. The Tightening Skin Cream or Spray can be found at health food stores and at drug stores. How To Store Tightening Skin: Do not wash your Tightening Skin products in the sink. Keep your products in a cool, dry place. Do not store Tightening Skin in the refrigerator.
