Lactobionic acid powder is recognized as the "gentle all-round alpha-hydroxy acid" in the current skincare industry. It is also a third-generation PHA polyhydroxy acid raw material that differs from traditional strong acids. It is produced by oxidizing natural lactose and has a high purity, stable properties, and extremely low irritation. It is a multi-functional active raw material that combines exfoliation, moisturization, repair, and anti-aging functions.
Unlike the drawbacks of strong exfoliation and easy redness of ordinary alpha-hydroxy acids, lactobionic acid has an ultra-large molecular structure and will not deeply stimulate the skin. It only gently removes surface old and dead keratin. It can not only unclog pores, improve closed blackheads, and roughness and dullness, but also will not damage the skin barrier. Sensitive skin and fragile skin can also use it with peace of mind. It is truly a "gentle chemical exfoliant" ingredient.
At the same time, lactobionic acid has multiple hydrophilic hydroxyl groups, and its water absorption and retention ability are extremely strong. It can not only quickly replenish skin moisture, relieve dryness and peeling, but also repair damaged barriers, enhance the skin's own water retention ability, and keep the skin texture long-term smooth and hydrated.
In addition, lactobionic acid has excellent antioxidant and anti-glycation capabilities, which can effectively eliminate free radicals and resist external pollution damage. It can improve skin dullness, yellowing, sagging problems, and reduce skin color differences, making the skin transparent, clean, and delicate and bright.
