打造完美肌膚由B3 開始 / Vitamin B3 for a perfect skin

眾所周知，糖會加速衰老。 為什麼？ 我們能否減慢皮膚老化速度？

簡單來說，身體有一個機制叫糖化， 這個過程中，蛋白質或脂質會被糖糖化。這個機制會因糖的數量加速。 年齡、環境、壓力等因素亦有影響。

經過一系列分子反應後會產生老化標記，稱為『糖化終產物』（“AGEs”），並與膠原蛋白和彈性蛋白交叉鏈接。

被糖化的膠原蛋白及彈力蛋白質會變硬，失去功能。久而久之，皮膚會變薄，失去彈性以至蠟黃， 鬆垮與皺紋。皮膚最早在20歲左右便有糖化的膠原蛋白。

AGEs和糖化膠原蛋白及彈力蛋白是不能逆轉的，但可以抑制。不同的研究發現維生素B3（niacinamide菸鹼酸）可幫助抑製糖化，從而減少膠原蛋白和彈性蛋白的交叉鏈接。

其實，維生素B3具有很全面的抗衰老功能， 它還有助於改善表皮屏障功能，減輕皮膚色素沉澱，減少細紋和皺紋，減輕發紅和斑點，並改善蠟黃和彈性。

膠原注養美膚精華02就添加了維生素B3， 不僅刺激膠原蛋白產生，還有保護膠原蛋白的作用。

It is well-known that sugar could accelerate ageing. Why? And could we slow it down for the skin?

To simplify, sugar is used for the glycation of protein or lipid in our body. This process could be accelerated with sugar. Age, living environment and stress level, etc., are also factors affecting the speed of glycation

After a series of molecule reactions, the ageing marker “AGEs” and collagen and elastin cross-links will be produced.

The collagen/elastin cross-links are stiff, rigid and non-functional. Ultimately skin becomes thinner, less elastic and sallow. Glycated collagen on human skin could be first observed at age around 20.

AGEs and the cross-links cannot be reversed, but can be inhibited. Vitamin B3 (Niacinamide) is found to inhibit glycation and thus to reduce collagen and elastin cross-links being formed. A number of studies have supported this.

In fact, the anti-ageing function of vitamin B3 is all-round. It also helps to improve epidermal barrier function, lighten skin hyperpigmentation, reduce fine lines and wrinkles, calm skin redness and blotchiness, and improve sallowness and elasticity.

With Vtamin B3, our Skin Bouncing Beauty Serum 02 does not just stimulate production of collagen, but also preserves its texture.
