Skin care information and tips from the aestheticians at UW Health Transformations Jeune Skin Care


The end of summer is just around the corner. For many families with children and those individuals in college, the time has come to prepare for another school year. The thought of alarm clocks, schedules, books and homework is enough to make some people stay in bed a little longer and enjoy the lazy days of summer.


Yet not all learning requires studying and reports to follow. Ready to get educated about your skin? Read on for some fun facts…

  • The skin is the largest organ of the body. An average adult's skin spans 21 square feet, weighs nine pounds, contains more than 11 miles of blood vessels and accounts for roughly 15% of your body weight.

  • The 6 functions of the skin are protection, absorption, secretion, sensation, excretion and heat regulation.

  • Your body will shed enough dead skin cells in your lifetime to fill an overly large suitcase. Dead skin comprises about 50% of the dust in your home.

  • The skin is made up of three main layers:
    • Epidermis (top)
    • Dermis (middle)
    • Subcutaneous/sub dermis (bottom) layer

  • The Epidermis consists of 5 layers all with distinct functions. Listed from bottom to top they are:
    • Stratum Basal/Germinativum (base layer)
    • Stratum Spinosum (spiny layer)
    • Stratum Granulosum (granular layer)
    • Stratum Lucidum (clear layer - absent on the palms of the hands and soles of the feet)
    • Stratum Corneum (horny layer - the Stratum Corneum is the top, uppermost layer and is what we exfoliate; it's comprised of dead, hardened keratinocytes known as skin cells)

  • One can compare a new skin cell at birth in the Stratum Basal/Germinativum to a fresh, juicy grape that contains about 85% moisture. By the time the skin cells goes through all their necessary functions and rise to the top (Stratum Corneum), they retain only 9-15% moisture and can be likened to resembling a raisin. Here, they slough off, revealing new, healthier skin.

  • The process of new cell birth and turnover drastically slows down as we age, from roughly every 12 days before puberty up to a couple months as we approach mid-life. The skin can appear dull and lifeless, with fine lines becoming more apparent. Exfoliation to the rescue!

  • The Dermis consists of the papillary layer (upper dermis) and reticular layer (lower dermis), consisting of proteins like collagen and elastin, a network of nerve fibers and blood vessels.

  • The subcutaneous/sub dermis layer consists of fat used as a fuel reserve, insulation and cushioning.

  • Skin color comes from a protein called melanin (pigment). Melanocytes originate in the Stratum Basal/Germinativum layer of the epidermis, which produce and distribute melanin. Roughly 1 melanocyte injects 36,000 skin cells with melanin.

  • Everyone has the same amount of cells that produce melanin, but darker skin types produce more melanin.

  • The skin on your eyelids is the thinnest and skin is thickest on the soles of the feet.

  • The lips do not have sweat glands, which is a reason they tend to dry out quicker than other areas of the body.

  • The face is comprised of 14 facial bones and 43 facial muscles, of which about 20 muscles are used for facial expression alone. The muscle that puckers the lips is the orbicularis oris muscle, and is the most significant muscle used for kissing. So, pucker up!
