“A wrinkle is only a sign that a smile has been there.” We may be able to borrow this quote from Mark Twain to comfort beauty lovers, but our ultimate goal is to both fade those wrinkles and not let the candidate lose the habit of smiling. Age will always leave some marks on our face, more or less. One day when you are looking at your makeup in the mirror, you suddenly find that wrinkles are actually creeping up on your forehead and eyes. So, some people are “scared” and find a doctor to find a solution. Others wait until the wrinkles deepen and makeup is too hard to cover them up, hoping that the doctor can quickly and effectively make them disappear. In order to solve the problem of wrinkles, it is necessary to know the cause of their appearance. What exactly is wrong with the skin that causes wrinkles to appear? It is because the collagen, active substances and oxidized cells in the cell membrane tissues have been damaged. In other words, the appearance of skin lines indicates that the skin has been damaged or destroyed in some way, presenting the result as skin aging. In more graphic terms, the support of the skin has loosened and the skin has been stretched. To eliminate wrinkles, the damaged collagen, active substances and oxidized cells have to be repaired. There are a variety of skin care products on the market that are designed to “remove wrinkles”, but after using them for a period of time, beauty seekers find that wrinkles are not eliminated and skin problems still exist. The reason for this is simple, putting aside whether these “wrinkle” skin care products contain ingredients that can make wrinkles eliminated, not to mention the good skin care products, if only applied to the skin, but also in the superficial work, not really repair the role of the skin. Taking care of aging skin is like repairing an old house that has been exposed to the elements, it’s not easy! The only way to repair the broken areas without destroying the original foundation, without damaging the skin, and to rejuvenate the skin, is to regularly and actively try to balance the “aging→repair” process. This is the only way to maintain a young, healthy skin. There is a relatively long process of skin damage and repair. When the exposed epidermis is damaged over a long period of time, a series of chain reactions occur. To help the injured epidermis recover, the dermis continuously supplies it with nutrients. Over time, the dermis becomes “malnourished” due to the loss of nutrients. As the dermis becomes malnourished, collagen is lost and cannot be produced, thus depriving the skin of the support of elastic fibers and accelerating the rate of skin aging. The inability of the dermis to balance the “aging→repair” process leads to poor blood circulation and endocrine system function, and a decrease in the biological synergy of fibroblasts, which in turn leads to atrophy and aging of the subcutaneous tissue. The series of reactions of the subcutaneous tissues, which are invisible to the naked eye, are manifested on the epidermis as atrophy → relaxation → collapse → wrinkles → blemishes. When the epidermis appears loose, sagging, drooping, concave and other symptoms, the whole person will look much older. This aging will further affect the whole skin layer, making the whole circulatory system of the skin worse, the immune system weaker, and the ability to absorb nutrients will also become weaker. The lack of nutrient supply in turn leads to deteriorating skin health. This is a vicious circle! At this point, coupled with the artificial “wrong beauty”, using various means in the epidermis or subcutaneous tissue indiscriminately injected, not only can not let the dermis to get repair, but will let it breathe. In short, the dermis is the layer of skin that is damaged by aging. Only by allowing nutrients to break through the epidermis and enter the dermis and subdermis can the dermis be effectively repaired, thus slowing down aging. But to do this, we need to use the power of “micro-needling”.
