What is the cause of my dry lips? When your skin cells are less active, the collagen network that provides skin firmness and structure breaks down. The skin then becomes dehydrated and forms lines and wrinkles, appearing as lines, white unsightly dead skin, which can even cause cracks on your lips. How Lip Sleeping Mask restores healthy lips? Lip Mask rapidly triggers new collagen fiber growth, restoring healthy glossy smooth lips. Studies have shown that up to 90% of collagen peptide are absorbed into the body within few hours of application. Collagen peptides are highly bioavailable. They act as building blocks, renewing bodily tissues. Night Treatment VS Day Treatment One application of the Lip Mask overnight can be up to ten times more effective in caring for your lips than using ordinary lip balms. Maximize your rest time for lip care, when all muscles are relaxed and movements are minimized, allowing for greatest absorption. How to use: 1. Scrub the lip mask on the lips before going to bed to remove the aging cutin. 2. Nourish lips with a thermal lip mask. Prompt: 1.
