When it reaches the outer layer, or surface layer, the skin cell dies and is eventually shed through a process called desquamation. During its life cycle, a skin cell travels up through the epidermis to the dermis until it reaches the skin’s outermost layer (called the stratum corneum). Skin cells - also called keratinocytes - are composed of a protein called keratin and are formed in the epidermis.
Our skin has sebaceous glands that produce naturally hydrating oils and a built-in process that constantly produces new skin cells while shedding the old. Check out some of the most common causes, ahead. While sloughing away dead surface skin cells through chemical and physical exfoliation is a great way to reveal a glowing, radiant complexion, it’s important to know what’s causing your skin cells to build up in the first place. Causing everything from a dull skin tone and sallow skin to clogged pores and breakouts, dead skin cell buildup is a common skincare concern.
