광고 什么是玻尿酸？
透明质酸是一种多糖分子（一种大型复杂碳水化合物），也称为玻尿酸。它由我们的细胞生成，天然存在于人体内。它与胶原蛋白和弹性蛋白一起，是构成皮肤细胞周围结缔组织的主要成分之一，为皮肤提供水分和紧致度。
年轻健康的皮肤含有大量的透明质酸，但随着年龄的增长，皮肤产生的透明质酸会减少，现有的储备也会耗尽 弘大皮肤科。
为什么玻尿酸对我的皮肤有益？
透明质酸是一种强效保湿剂，它就像磁铁一样，能将水分吸引到皮肤。它可以吸收自身重量1000到10000倍的水分（即1克透明质酸可以吸收1到10升水）。透明质酸还能防止皮肤水分过度流失，因此对维持皮肤水润至关重要。保持最佳水润度是皮肤健康的关键：如果水分不足，皮肤会干燥，保护屏障功能也会下降。从视觉上看，皮肤会失去光泽和紧致度。
随着年龄增长，皮肤细胞产生的透明质酸减少，现有的透明质酸也开始降解。这会导致皮肤干燥，也是造成皮肤衰老迹象（如细纹和皱纹、皮肤容量减少和弹性下降）的因素之一。
Research has demonstrated the value of certain forms of Hyaluronic Acid as an ingredient in topical skincare where it helps boost skin moisturization and plump skin thereby reducing the appearance of wrinkles. It is also tried and trusted by dermatologists as an ingredient in dermal filler injections used to reduce the visible signs of skin aging.
All skin types benefit from skincare products that contain an effective Hyaluronic Acid formula, but they are especially effective on skin that is naturally dry and from the mid-20s when skin starts to show the first signs of aging.
What are the different types of Hyaluronic Acid?
Hyaluronic Acid comes in different molecular weights and some formulations are more effective than others. It’s not enough to be told that a product contains Hyaluronic Acid: always be sure to buy products from a brand you trust with research results that prove effectiveness and skin compatibility.
There are three main types of Hyaluronic Acid used in topical skincare:
High molecular Hyaluronic Acid (also known as long-chained). This remains on skin’s surface and works to improve hydration in the outermost layer of the epidermis – where fine lines and wrinkles originate.
Medium molecular Hyaluronic Acid (also known as medium-chained) works in a similar way to high molecular Hyaluronic Acid.
Low molecular Hyaluronic Acid (also known as short-chained). With molecules that are 40 times smaller1 than those of high molecular Hyaluronic Acid, low molecular Hyaluronic Acid penetrates further into the epidermal layers where it stimulates skin’s own production of Hyaluronic Acid, replenishing moisture where deeper wrinkles originate.
Eucerin uses both high and low molecular Hyaluronic Acid in the Hyaluron-Filler2, Hyaluron-Filler + Elasticity, Anti-Pigment Dual Serum and Sun Photoaging Control formulas to effectively target and plump wrinkles from the inside out. The Eucerin DermatoCLEAN [HYALURON] range of cleansers and Eucerin Hyaluron-Filler + Volume-Lift include low molecular Hyaluronic Acid.
All Eucerin formulas are the result of innovative research and development and 130 years of skincare expertise. They are clinically and dermatologically proven to be both highly effective and well tolerated by skin.
1 The standard unit for measuring the mass of an atom is a kilo Dalton (kDa). High molecular Hyaluronic Acid has a kDa of 2000 and low molecular Hyaluronic Acid has a kDa of 52.
2 With the exception of Eucerin Hyaluron-Filler Moisture Booster which combines medium molecular (rather than high molecular) Hyaluronic Acid with low molecular Hyaluronic Acid
How can I incorporate Hyaluronic Acid in my daily skincare routine?
Eucerin DermatoCLEAN [HYALURON] is a range of hydrating cleansers (gel, milk, micellar foam and micellar water) plus a toner and an eye make-up remover.
Clinically and dermatologically proven to cleanse gently and effectively, they combine an extra mild cleansing complex with Hyaluronic Acid and other moisturizing ingredients that protect skin’s natural moisture and don’t dry it out. Suitable for all skin types, they leave skin feeling clean, soft and hydrated.

Eucerin offers an extensive selection of care products which maximize the hydrating benefits of hyaluronic acid for your skin. Our three ranges are tailored to every major stage of the skin aging process and their effectiveness is clinically and dermatologically proven:
Eucerin Hyaluron-Filler tackles the first signs of aging such as fine lines and wrinkles. It plumps up even the deepest wrinkles for a rejuvenated look.
Eucerin Hyaluron-Filler + Elasticity nourishes fragile and mature skin. It plumps up deep wrinkles and improves elasticity.
One of the negative effects of too much sun is that it dries out skin and leads to photoaging (premature aging caused by the sun).
Eucerin Sun Fluid Photoaging Control SPF 50 is an everyday facial sunscreen that offers the very best in sun protection. The formulas are further enriched with Hyaluronic Acid and visibly reduce wrinkles on the face and decollete.
What else can I do to keep my skin hydrated?
Healthy lifestyle choices will help you to keep your skin looking soft, smooth and firmer for longer. Try to get plenty of exercise, eat a balanced diet, drink lots of water, limit your alcohol consumption, give up smoking and get a good night’s sleep.
