Being winter and having really dry dull skin, I think we are all exfoliating like crazy to try and get that smooth glow again.
[Exfoliation is the removal of the oldest dead skin cells on the epidermis and helps to maintain a glowing healthy skin, but like most things done in excess over-exfoliation is bad for your skin. Sonette Donker from Dermalogica South Africa explains why:
“Over-exfoliation is the drawback and downside to having such great ingredients at our disposal. We know this has led to more environmentally sensitized skin and possibly aging. We may tell our clients to exfoliate 2-3 times a week, but they don’t listen to us because they like the way their skin feels after exfoliation. As a consumer we love how our skin looks after exfoliation – “I don’t care if my therapist says only 2x a week, I want to do it every day, even if you tell me not to!”
But what happens if we are looking under a magnifying lamp? Have you looked at your skin in a magnifying lamp? We sacrifice the integrity of the epidermis which leads to sensitized skin. The cosmetic chemists have been aware of the problem, so the latest research has been concentrating on looking for exfoliating ingredients to use that will exfoliate, but can be used every day without compromising the integrity of the skin.
Signs of over exfoliation;
•Noticeable dehydration and patchy areas.
•Irritation and breakouts.
•Transparent looking skin.
•Redness, couperose, signs of early rosacea.
Dangers of Excessive Exfoliation (less wrinkles today could mean more wrinkles tomorrow)
Removal of the outermost layer of the skin stimulates the cells in the lower layers to grow and divide, causing the skin to thicken and thus diminishing visible signs of aging. The more you exfoliate the more cell divisions will occur in the lower skin layers. There is one problem though. Normal human cells cannot divide indefinitely. Fibroblasts (a key type of cell in the skin) would divide about 50 times and then enter a so-called stage of senescence.
This ‘theory’ of cell division is called the Hayflick Limit (named after its discoverer Dr. Leonard Hayflick). His studies show that in this stage the cell is sluggish, inefficient and unresponsive to various signals from the body and unable to divide. Skin with many senescent cells is usually fragile, blotchy and easily wrinkled. Exfoliation remains a valuable tool but if you over-use it, your skin may hit the Hayflick Limit.
Today’s good news is that the Hayflick Limit does not appear to be carved in stone. Research indicates that very simple measures available today may help to extend it by as much as 50%.”
A bit technical – but you get it right?!
I myself love to exfoliate daily, and Dermalogica has 2 daily exfoliators. Daily Microfoliant and Daily Resurfacer – I am currently testing the Daily Resurfacer and I must say I am loving the way my skin is looking – I will post my review next week.
