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。
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.
