Ceramide protects the skin from external stressors
Betaine is useful in anti-aging products to help prevent wrinkles. Its moisturizing properties soften skin's texture and effectively fill in creases to reduce the deep appearance of wrinkles.
Glycerin is a skin-replenishing ingredient that helps to establish normal balance. It also gives hydration to all skin types. In addition, it helps skin maintain a healthy look and feel, defending against dryness. Further, it works to maintain skin’s moisture level.
