How Long Does It Take For Your Skin To Renew?

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.

Skincare Ingredients Which Boost Skin Cell Renewal

Studies showed that these following skincare ingredients improve the skin's ability to renew itself and repair damages:

  1. 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.
  2. 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.
  3. Salicylic acid aka beta hydroxy acid (BHA) accelerates skin cell renewal and reduces the sebum secretion. It is best for blemish-prone, oily skin.
  4. 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.

Exfoliate Daily To Boost Skin Cell Renewal

Regular exfoliation is the key to a long-lasting radiant complexion. It removes dead skin cells, boosts cellular renewal and reduces the signs of ageing. Choose a non-abrasive exfoliating formula like Night Repair Skin Cell Renewal Booster which has been formulated with 5 alpha hydroxy acids: glycolic acid, lactic acid, citric acid, manic acid and tartaric acid. 

For sensitive skin opts for Rose Royale Supreme Anti-Ageing Serum which has the optimum concentration of n-acetyl glucosamine and niacinamide. While for those with blemished-prone oily skin, choose Anti Blemish Clarifying Serum which has been formulated with salicylic acid, lactic acid and citric acid.
