While biology lessons tell tales of your heart, lungs, kidneys and appendix, your skin is largely a topic left unturned. Let’s fix that. Did you know the facts listed below?
1. Regardless of Your Skin Type, Everyone’s Skin Is Oil-Based
It’s like water off a duck’s back. The health of your skin is mostly dependant on the vitality of its top layers. These need to be waterproof to avoid dilution, barrier-forming to prevent bacterial invasion, and firm enough to zip in hydration.
That’s one hell of a task, and your body does this perfectly using simple science. Oil and water don’t mix. The top layers of skin are mostly made from oil and they’re kept in tip-top condition by the oily sebum your skin’s hair follicles secrete.
2. Your Skin Can Tell Time, and That Affects Things Like Sebum Secretion
Ever noticed your skin is oilier at certain times of the day? Ever wondered why night creams are heavier than day creams? This is your answer: Your skin can tell the time of day. Just like your body naturally wakes to light, so, too, does your skin.
Studies show that skin constantly lubricates itself with sebum. This process is constant but not even. Ramping up in the morning, skin works towards a maximum level of oil by at midday, and from there it’s a downward slide until your lowest point is reached after lights off (1).
This means at night your skin’s in perfect condition to absorb an intensely conditioning nighttime cream.
3. Skin Renews Itself Almost Completely Every 39 Days
Skin that is young and healthy has a life cycle on the low side of 39 days (2). This keeps skin fresh, radiant and even. Your skin is constantly renewing and it has been your entire life. Have dark marks left by pimples? Grazes left by kickboxing? Your 39 days cycle should have those evened out in just a month or two.
4. Skin Is Your Largest Organ
Skin is pretty quiet most of the time, even though it’s a human being’s largest organ, weighing in at an average of 20 pounds (the weight of a car tire) and covering 22 square feet (the size of a small bathroom) it’s also your largest and your heaviest organ (3).
5. All Healthy Skin Contains Bacteria - Welcome to Your Microflora
Have you ever eaten probiotic yogurts or invested in immunity-building fermented drinks? If you have, you’ll already be very familiar with the concept of good vs. bad bacteria. The human body is home to many.
While the health of gut bacteria is becoming a well-researched field, the health of your skin’s microflora is only just beginning to come to light. Acne, for instance, is not just a matter of having blocked pores. To have diagnosable, clinically proven acne, skin must have an overgrowth of a certain bacteria called propionibacterium acnes (4).
When your microflora is healthy, your skin behaves perfectly. Want to keep it that way? Be sure to care for your skin sensitively.
