The skin has the mission to protect our body from the penetration of harmful substances. However, while blocking the penetration of harmful substances, it also blocks the penetration of care products, preventing them from reaching the dermis and below the dermis, which in turn does not serve the purpose of deep skin care. However, as mentioned earlier, it is possible to deliver care products to the dermis and below if micro-needles and roll-on needles are used. And the easiest way to do this is with microneedling. How does microneedling deliver care products to the dermis and below the dermis to care for the skin? Microneedling is a non-thermal or micro-thermal physical stimulation of the dermis that causes very minor damage to the dermis in a minimally invasive way, supplying the dermis with the necessary micronutrients for repair. Micronutrients enter the dermis and sub-dermis, slowly activating the skin’s own repair functions, stimulating fibroblast growth, and releasing growth factors needed for new collagen, increasing skin hydration, brightness and firmness. After the repair process, the skin functions normally, and the skin appears healthy. Although microneedling is not the only means of delivering care to the dermis and below, the advantages of microneedling are clear. For example, it does not damage epidermal tissue and is moderately strong, allowing for rapid skin repair. At the same time, it circumvents the possibility of complications such as re-darkening or photosensitivity during photo-thermal energy sessions. The Micronutrient supplementation method is similar to the principle of dermal matrix therapy in the field of anti-aging abroad. Dermal matrix therapy has long been popularized and promoted in the foreign medical community. It first emerged in France, Switzerland, Spain and other European countries. The core of dermal matrix therapy is to replenish the nutrients in the matrix. The dermal matrix has the function of initiating fibroblasts and epidermal basal cells, thus, the dermal matrix determines the morphology and division of cells, which in turn promotes the synthesis of collagen and elastin. In contrast, Micronutrients break through the epidermis through microneedles and enter the dermis and below the dermis to provide the skin with the nutrients needed for cell metabolism and rejuvenate the skin. Tips: Q: What are the main applications of Micronutrient supplementation on problematic skin? A: Wrinkles, blemishes, dullness, dry pores, reduced elasticity, aging skin atrophy, epidermal keratinization, poor satiation, and abnormal blood vessels. Q: What are the ingredients of the commonly used Micronutrients? A：Commonly used Micronutrients such as various vitamins, stable amino acids, cellular minerals, biological coenzymes, cellular nucleotides, hyaluronic acid and other substances required by skin cells.
