The products you use during the SkinPen healing process are important for best results. One of the fundamental goals of skin rejuvenation is to revive the skin’s natural structures, namely collagen, elastin and extracellular matrix. The SkinPen micro-needling procedure accomplishes this goal by creating micro-injuries that trigger your body’s natural wound repair process. When your dermis is injured, your skin repairs itself by initiating a three-stage wound healing process that includes the remodeling of collagen. Here’s a breakdown:
Inflammation. When dermal tissue is pierced, your immune system springs into action. White blood cells, which include macrophages, disinfect the wound, remove debris and increase blood flow to the wound area. The swelling and skin redness you see after an injury are signs of inflammation. The maximum inflammatory response occurs during the first day after your SkinPen micro-needling procedure. Because inflammation is thought to play a key role in scar formation during the wound healing process, reducing inflammation is critical during this initial phase and throughout the 28-day healing process after micro-needling. Therefore, it’s important to avoid ingredients that increase the risk of inflammation and/or hinder the skin’s natural repair mechanisms, including:
- Formaldehyde-releasing preservatives
- Citrus-derived preservatives
- Sulfates (e.g., sodium lauryl sulfate)
- Glycol (e.g., propylene glycol)
- Mineral oil
Prime offers topical post-micro-needling products formulated specifically to optimize the results of micro-needling. These products help to minimize inflammation during the 28-day skin remodeling process following the SkinPen micro-needling procedure and do not contain any of the irritating ingredients listed above.
Proliferation. This stage is when the repair process begins. The wound is re-built with new granulation tissue — a combination of cells, collagen and other extracellular matrix materials. Several important processes occur during proliferation:
Granulation. Fibroblasts (the cells of the dermis) move to the wound area. Fibroblasts produce collagen and elastin in the wound site, forming connective skin tissue to replace the damaged tissue. Healthy granulation tissue is uneven in texture. It does not bleed easily and is pink or red in color.
Revascularization. A new network of blood vessels develops to deliver the oxygen and nutrients your fibroblasts need during the reconstruction process.
The proliferation phase is short (approximately five to six days) after micro-needling because you’re not damaging very many skin cells. Micro-needling pushes the skin cells aside with only minimal damage to the epidermis and dermis.
Remodeling. During the final stage, newly formed collagen is rearranged and converted from type III to type I. This type of collagen adds strength to the wound, and the process causes the dermis to contract slightly, pulling the wound edges together and closing the wound. This is like a shrink-wrap effect that tightens the skin. Most of the remodeling process occurs within one to six months of the SkinPen micro-needling procedure. Older individuals (55 years or older) may need longer for wounds to heal. Cell nutrition is very important during this remodeling stage which is why it’s so important provide key nutrients that your skin needs during remodeling, including vitamin C, vitamin A and copper peptides.
