The skin is broken up into three layers: the Epidermis, the Dermis and the Subcutaneous. Our (esthetician's) scope of practice is in the Epidermis only!
The Epidermis is made up of five layers, three of which are composed of dead cells: Stratum Corneum (dead), Stratum Lucidum (dead), Stratum Granulosum (dead), Stratum Spinosum and Stratum Germinativum. The Stratum Spinosum and the Stratum Germinativum are considered one layer, the Basal layer. (So, technically there are four layers). Keratinization is when live cells are converted into dead protein cells. Since the first three layers are dead, this is where Keratinization occurs (it starts in the Stratum Granulosum and works up).
A way to remember each layer:
Stratum Corneum is rough or "corn-y."
Stratum Lucidum is clear or "transLUCID."
Stratum Granulosum is "Gran-y (grainy)" and has tiny granuals.
Stratum Spinosum is "spiny" and has spiny layers.
Stratum Germinativum is always "germinating" or reproducing through mitosis.
And a way to remember the order:
