How Does the Stratum Spinosum Contribute to Skin Renewal?
The stratum spinosum plays a vital role in the process of skin renewal. As keratinocytes move from the basal layer to the stratum spinosum, they begin to produce more keratin and become more resilient. These cells eventually move up to the stratum granulosum and then to the stratum corneum, where they form the outermost protective layer of the skin.
