How Long does it take for Your Skin to Renew?


" Studies showed that topical vitamin C boosts skin cell renewal, promotes collagen synthesis and prevents photoageing."


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. A healthy skin renewal cycle is the key to an even, spotless radiant complexion.

Ageing and Skin Renewal Process

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 skin to repair and replace the damaged cells. The longer it takes for your skin to renew itself, the more built-up dead skin cells on the top layer of the skin waiting to be replaced. These excess dead skin cells make your complexion look dull and tired.

Vitamin C Boosts Skin Cell Renewal

Studies showed that topical vitamin C boosts skin cell renewal. Vitamin C promotes collagen synthesis in the skin of people across age groups from young to old. It is also known to protect the skin from free radicals and photoageing. However, to get the best results, choose a vitamin c skincare product that contains L-ascorbic acid, the most active and effective form of vitamin C.

L-ascorbic acid is the main ingredient of the multi-award winning vitamin C serum, Antioxidant Youthful Essence. This powerful yet gentle anti-ageing formula contains a unique blend of L-ascorbic acid, ferulic acid, vitamin E, pro-vitamin B5 and botanical extracts to boost cell renewal, promote radiant skin and reduce the appearance of wrinkles, lines, blemish and pigmentation spots. It is suitable for all skin types. For best possible results, apply Antioxidant Youthful Essence twice a day, morning and evening, underneath your moisturiser.

Regular Exfoliation is The Key to A Long-Lasting Radiant Glow

The top layer of the skin contains dead cells that make skin look dull. To make sure that your skin will never look dull, exfoliate your skin regularly. Regular exfoliation is the key to a long-lasting radiant complexion. It boosts skin cell renewal and reduces the signs of ageing such as wrinkles, lines and uneven skin tone. It brings back the healthy glow and makes your skin look younger and fresher.

For radiant skin all year round, gently exfoliate your skin every night. Again, the most crucial thing with skin exfoliation is being gentle to your skin. Choose a gentle non-abrasive face exfoliator like Overnight Skin PerfectorFor best results, apply this complexion repair serum to freshly-cleansed face and neck avoiding the immediate eye area. This complexion repair serum gently exfoliates dead skin cells, restores radiance and reduces the appearance of wrinkles and lines.

How to Boost Skin Renewal At Night?

Your skin renews itself particularly at night while you are at sleep. If for any reason, you don't want to use vitamin C serum on daily basis, you can boost your skin renewal at night by using a skincare product that contains alpha and beta hydroxy acids such as citric acid, glycolic acid, malic acid and salicylic acid.

Studies showed that alpha and beta hydroxy acids boost skin cell renewal and even out skin tone. For Overnight Skin Perfector, I use a combination of citric and salicylic acid to refine pores, boost skin radiance and smooth out wrinkles. I also add blue chamomile essential oil and liquorice root extract to help prevent skin-irritation and protect skin cells from premature ageing. Studies suggest that liquorice root extract helps reduce the appearance of age spots due to excess melanin production in the skin. 

How To Boost Skin Renewal In Sensitive Skin?

Hyper-sensitive skin may not be able to tolerate L-ascorbic acid, alpha or beta hydroxy acid; however, it doesn't mean that people with sensitive skin can't boost their skin cell renewal. Active skincare ingredients like niacinamide (vitamin B3) and n-acetyl glucosamine can be greatly beneficial for sensitive skin.

Niacinamide soothes sensitive skin and strengthens skin's barrier functions. It has been shown to increase the production of collagen, elastin and other proteins in the skin by up to 100%. It works synergistically with n-acetyl glucosamine to boost skin renewal and reduce pigmentation spots. Studies showed that both ingredients prevent the excess production of melanin pigment in the skin. N-acetyl glucosamine gently peels off dead skin cells and diminishes the appearance of wrinkles without causing irritation, hence it is suitable for even very sensitive skin.

The award-winning Bio-Collagen Serum has been formulated with n-acetyl glucosamine, niacinamide, 24-karat gold and nano hyaluronic acid with its ultra-low-molecular-weight particle of 0.0000000000000000001 gram that penetrates deeper into the skin to deliver key ingredients, nutrients and oxygen. This ultra firming anti-wrinkle serum rejuvenates and restores the youthfulness of the skin from within. It speeds up skin cell turnover, brings back the radiant glow and diminishes the appearance of wrinkles and pigmentation spots. For best possible results, apply Bio-Collagen Serum on freshly-cleansed skin every morning and evening, follow with Bio-Collagen Ageless Cream.
