Abstract

The present disclosure generally relates to methods and compositions for treating skin. In some embodiments, the method uses an exfoliation tool. In some embodiments, the method uses an exfoliation tool together with selected skin care agents or compositions.

Claims

1. A method of skin treatment comprising:

(a) treating the skin with an exfoliation tool, wherein the exfoliation tool comprises a handle and a head, the head comprising a roller, a collar, and a plurality of steel acupuncture needles located on the roller; and

thereafter

(b) applying a first skin care composition to skin, the skin care composition comprising myristoyl pentapeptide-8 or myristoyl tetrapeptide-8; and

(c) applying a second skin care composition to the skin, wherein the second skin care composition is different from the first skin care composition.

2. A method of skin treatment comprising:

(a) treating the skin with an exfoliation tool, wherein the exfoliation tool comprises a handle and a head, the head comprising a roller, a collar, and a plurality of steel acupuncture needles located on the roller; and

thereafter

(b) applying a first skin care composition to skin, the skin care composition comprising;

i) myristoyl pentapeptide-8 or myristoyl tetrapeptide-8 and an optional peptide selected from the group consisting of sericin, silk protein, collagen, keratin, amino acids, hexapeptide-21, oligopeptide 10, palmitoyl hexapeptide-14, palmitoyl oligopeptide, palmitoyl tetrapeptide-7, tetrapeptide-16, arginine, lysine, betaine, milk solids, rice peptides, and derivatives and combinations thereof;

ii) at least one skin conditioner selected from the group consisting of hyaluronic acid, alpha hydroxyl acids, glycolic acid, lactic acid, ascorbic acid, polyhydroxy acids, gluconolactone, lactobionic acid, beta hydroxyl acid, peat extract, arginine, glycine, and derivatives and combinations thereof;

iii) at least one moisturizer selected from the group consisting of butylene glycol, propylene glycol, ethoxydigycol, hydroxyethyl urea, glycerin, triglycerides, natural oils, olive oil, jojoba oil, soybean oil, soy, coconut oil, silicone, shea butter, dimethicones, lanolin, coco butter, avocado, bisabolol, ceramide, panthenol, lecithin, tea tree oil, and derivatives and combinations thereof; and

iv) at least one antioxidant selected from the group consisting of retinol, BHT, tetrahexyldecyl ascorbate, ascorbyl palmitate, retinyl palmitate (vitamin A), ascorbic acid (vitamin C), tocopheryl acetate (vitamin E), feverfew, hydroxytyrosol, CoQ10, resveratrol, carotenoids, alpha lipoic acid, and derivatives and combinations thereof, and

(c) applying a second skin care composition to the skin, wherein the second skin care composition is different from the first skin care composition.

3. The method of claim 2, wherein the needles on the exfoliation tool are from about 0.1 mm to about 0.5 mm in length.

4. The method of claim 2, wherein the second skin care composition is applied to skin before treating the skin with the exfoliation tool.
