The outermost part, the epidermis, is the esthetician's area of expertise and the part of the skin we can directly a ect. Each layer of the epidermis has an important job, and professional treatments, as well as home care, can support each layer. When addressing client concerns, it's critical to remember what each layer does. As estheticians, we sometimes tend to focus on the surface of the skin without addressing the root cause of what's happening. Understanding the mechanisms of each layer and how speci c ingredients can help gives an expanded view of how we interact with the skin—both in and out of the treatment room. STRATUM GERMINATIVUM Also referred to as the basal layer, this is the innermost layer of the epidermis. The single-cell layer contains skin stem cells, which divide to create more stem cells and keratinocytes (skin cells). Keratinocytes make up 95 percent of the epidermis. That's a lot of skin cells! These cells transform dramatically as they travel through the di erent layers of the epidermis.Having healthy cellular membranes from the beginning will create skin cells that thrive on that journey. The stratum germinativum is also home to melanocytes, which produce the skin's natural pigment. Melanocytes are an essential part of the skin's protection and wellness. They are particularly sensitive. When melanocytes are functioning correctly, we have even skin tone and proper shielding from ultraviolet radiation (UVR) protecting cellular DNA. When melanocytes are distressed from trauma, hormones, or sun exposure, hyperpigmentation and hypopigmentation can occur.Following are some ingredients to support the health of the stratum germinativum and the cells that reside there.
