Skin Cell Turnover
As the largest and forever growing organ in your body, skin has the ability to renew itself regularly. Skin cell turnover is a repetitive process where the living cells from the lowest epidermis layer gradually moving up to the top layer of the skin. Then these skin cells die and shed off, revealing more radiant, younger-looking skin underneath.
Skin Renewal Process According To Age Group
The skin cell turnover rate varies individually and age plays a major role. In babies, the skin renews itself every 14 days. In teenagers, this process takes about 28 days. In adults, it takes between 28 and 42 days. In those age 50 and older, the skin renewal process can take up to 84 days. With age, it takes longer for your skin to repair and replace damaged cells, causing dead skin cells to build up on the skin's surface and complexion to look dull and tired.
Daily exfoliation helps boost skin cell renewal
Regular daily exfoliation is the key to a youthful, radiant complexion. It removes dead skin cells, boosts cellular turnover and reduces the signs of ageing. Daily exfoliation stimulates skin renewal, hence the damaged cells will be replaced with new, fresher cells faster.
Skincare Ingredients which speed up skin renewal
Studies showed that these following skincare ingredients improve the skin's ability to renew itself and repair damages:
- Niacinamide (vitamin B3) boosts skin cell renewal by significantly increasing the production of collagen, elastin and other proteins in the skin. It also helps soothe and protect the skin from photoageing.
- N-acetyl glucosamine speeds up the skin renewal process by dramatically increasing the production of skin's hyaluronic acid and collagen. It also gently peels off dead skin cells and diminishes the appearance of wrinkles, fine lines, dark spots and other signs of ageing. It is best for sensitive skin.
- Colloidal gold helps release Epidermal Growth Factor (EGF), Fibroblast Growth Factor (FGF) and Transforming Growth Factor (TGF) in the skin which stimulate skin cell regeneration.
- Alpha hydroxy acids (AHAs) stimulate skin cell regeneration by exfoliating and removing dead skin cells. Glycolic acid, lactic acid, citric acid, malic acid and tartaric acid ;are the most commonly used AHAs in skincare products.
- Salicylic acid which is also known as beta hydroxy acid (BHA) accelerates skin cell renewal and reduces the sebum secretion. It is best for blemish-prone, oily skin.
How To Boost Skin Cell Renewal
It is crucial for every adult to have a healthy skin renewal rate which the skin renews itself every 28 to 42 days. If your skin suffers from the lack of radiance, uneven skin tone or visible signs of ageing, use a skin cell renewal boosting serum like AGEless Serum. This serum has been formulated with 24 karat gold, niacinamide and n-acetyl glucosamine which are scientifically proven to stimulate cell regeneration. For best results, use the serum every morning and night to optimise skin renewal, remove dead cells and bring back the radiant glow.
AGEless Serum is a super potent, ultra-concentrated serum and suitable for all skin types including sensitive skin. Backed by 3 decades of intensive research and innovation, this renewal boosting serum lifts and firms up the skin while also improves density and elasticity. With regular daily use, the appearance of wrinkles, lines, dark spots and pores are visibly reduced. It doesn't contain AHA or BHA, so it is safe for use during the day and at night.
