Outer layer of skin that acts as a barrier between the body and the environment. Stratum corneum, uppermost layer, is made up of corneocytes (flat, dead skin cells) forming skin’s barrier. Basal layer, bottom layer, is where pigment is produced.
The epidermis sheds at a normal rate. Melanocytes produce a balanced amount of pigment.
The uppermost layer thickens, causing cells to stick together and clog pores.
The uppermost layer is thin and jagged due to lack of hydration. Cells shed inefficiently, sticking to each other and preventing new skin cells from reaching the skin's surface.
The uppermost layer is thin and jagged due to lack of water in certain areas of the face.
The skin's surface is red and uncomfortable. Nerve endings are inflamed.
Surface cells shed more slowly, causing dullness.
Inefficient desquamation (cell shedding) leads to clogged pores.
Melanocytes overproduce melanin at the very bottom of the epidermis. At the top of the epidermis overproduction of melanin leads to dark spots on skin’s surface.
Surface cells shed more slowly, causing dullness. The uppermost layer is thin and jagged due to lack of water.
Nerve endings are over stimulated. Capillaries dilate, causing skin redness. Rosacea can lead to acne-like lesions on the surface of the skin.
The skin's surface becomes red and irritated.
