Seen here in a scanning electron micrograph, the epidermis is a tough coating formed from overlapping layers of dead skin cells, which continually slough off and are replaced with cells from the living layers beneath. The epidermis is the outermost of three layers that make up the skin.
The epidermis is the visible and uppermost layer of your skin.
Its health is public data.
The epidermis is a mere 1/1000th of an inch thick, yet it can give rise to endless trouble and annoyance.
Inappropriate skin care can make its effects on the epidermis seen and felt for anywhere between 28 and 112 days, so you'll want to think twice before you fall into the popular trap of failing its requirements.
When attempting to rectify the health and functioning of the epidermis, you'll need to wait the same duration before assessing the benefit of any skincare you employ.
It is impossible to assess actual and lasting benefits to the epidermis by sampling skin care products, ceasing or interrupting prescribed treatment before such time has elapsed.
If healthy, the epidermis provides an attractive and efficient barrier against the environment and requires minimal skin care.
Among all the skin's layers, the epidermis provides the greatest financial support to establishments and brands providing notional care to liable individuals.
Most skincare coats this layer, leaving the wrinkle-prone, deeper dermal layer entirely untouched.
To re-iterate, the whole appearance of your skin depends heavily on the visible condition of less than a millimeter of skin — avoid compromising its vulnerable health.
Supporting Epidermal Health
Support and enhance the health of the epidermis by:
- only using an ideal facial cleanser;
- keeping the skin entirely and durably moist with a moisturizer than provides a generous amount of the optimal ingredients required for healthy skin barrier function;
- avoiding epidermal aggression or hardening by only implementing acidic skincare products, including those containing alpha hydroxy acids such as glycolic acid and ascorbic acid, as medically prescribed and periodically reviewed;
- not smoking and implementing ideal, chronic photoprotection;
- never using the Clinique 3 Step System;
- ignoring the M.D. Formulations Skin/Onion Peeling Analogy;
- simplifying your skin care, and avoiding the bulk of facials;
- generally avoiding chemical peels and laser treatments performed in a beauty therapy setting;
- promptly repairing considerable epidermal damage with an occlusive balm (such as Skinceuticals Hydra Balm or Vaseline) or a specialised treatment such as Skinceuticals Epidermal Repair.
Epidermal Functioning
The miracle starts in the lower layers of the epidermis, where new cells are continually forming.
As they mature, they slowly work their way to the surface, where after becoming depleted of moisture, they are sloughed off by environmental and deliberate skin care factors.
The Epidermis and Glycolic Acid
Glycolic acid may be used to accelerate shedding (exfoliation) by hastening the death and drying of skin cells.
Epidermis Definition
The epidermis is the outer layer of cells covering an organism, in particular (in zoology & anatomy) the surface epithelium of the skin, overlying the dermis.
In botany it is the outer layer of tissue in a plant, except where it is replaced by periderm.
