My Cosmetik Menthol Crystals are known for their cooling “ice cube” effect and the feeling of intense cold they provide. Very powerful active ingredients, they are used sparingly, especially in cosmetics for local use: toothpastes, decongestants or pain relievers, balms, etc. As the name suggests, pure menthol crystals are made from 100% menthol. Menthol molecules stimulate receptors in the skin that are receptive to cold. This reaction then decreases the sensitivity of the skin and gives the menthol crystals their analgesic, pain-relieving (muscle, blows, bruises, bruises, bruises), anti-inflammatory properties (calms irritation, itchy skin, etc.) and their very refreshing "thrill" effect. Menthol crystals also have antibacterial and antiviral properties, ideal for performing purifying mouthwashes that also have a fresh breath effect. Menthol crystals come from the crystallization of the essential oil of Japanese mint (Mentha arvensis) at a temperature of -22 ° C. This active ingredient is regularly used in the design of pharmaceutical products intended to relieve pain (due to its high concentration of menthol which is a powerful analgesic). Menthol crystals can also be used to freshen and purify the air. It is advisable to use in the preparation of oral care, deodorants, balms and milks, pain relieving gels, decongestants or refreshers, etc ... -Plumping lipstick: Melt in a bain-marie 0.8 g of beeswax with 2 g of cocoa butter, 2 ml of safflower vegetable oil and 0.1 g of menthol crystals (crushed with prior). Then remove the bowl from the double boiler and add 1 drop of vitamin E. Stir until a homogeneous mixture is obtained. Then transfer to the stick using the pipette. Leave to cool for a few hours in the fridge to speed up the process. Keep out of the reach of children. Do not use in children under 8 years old. Respect the recommended dosages. Do not ingest.
