Hyaluronic acid (HA) is a naturally occurring substance in the human body and a crucial component of connective tissue. In the skin, it plays an essential role in retaining moisture, providing lubrication, and nourishing tissues. It is currently recognized as one of the best natural moisturizers in existence and is often referred to as an ideal “natural moisturizing factor.”
Hyaluronic acid comes in two main molecular weights: high and low. High-molecular-weight HA locks in moisture, while low-molecular-weight HA penetrates into the dermis to nourish the skin. However, as we age or are exposed to environmental stressors, our natural HA levels decline. Therefore, hyaluronic acid not only hydrates but also serves as a filler to restore volume and structure.
As a highly biocompatible biomaterial, HA dermal fillers (玻尿酸填充) are now widely used and well-developed in aesthetic medicine. Once purified HA is injected into the skin, it integrates with the body’s existing hyaluronic acid, plumping the skin, smoothing wrinkles, and volumizing sunken areas. It also sculpts facial contours, enhancing definition and symmetry to achieve a more refined and three-dimensional appearance.
There are many types of hyaluronic acid products on the market today. So which brands are most commonly used in the UK?
STYLAGE 丝丽 Hyaluronic Acid
Stylage, developed by Laboratories Vivacy in France, is known for its innovative IPN-Like crosslinking technology. Often referred to in Europe as the “King of Contouring,” Stylage is designed to shape and volumize the face for a fuller, more youthful, and natural appearance that lasts.
What sets Stylage apart from other brands is the addition of mannitol (甘露醇), an antioxidant, making it the world’s first HA filler with anti-oxidative properties. Mannitol acts as a free radical scavenger—reducing oxidative damage to the skin and protecting the filler from breakdown, which also reduces post-injection swelling and redness. It slows gel degradation, making the results longer-lasting.
Stylage combines its antioxidant mannitol with its unique IPN-Like crosslinked HA. This technology involves blending two or more monophasic crosslinked HAs to form an interpenetrating network (IPN), which enhances stability, softness, and structural definition. The result is a filler with high moldability and low diffusion—perfect for contouring.
The Stylage range includes seven versions: HYDRO, Lips, S, M, L, XL, and XXL. Among these, M and XXL are the most commonly used in clinical settings.
Stylage products are CE-certified and marketed in over 50 countries worldwide.
TEOXANE 泰奥 Hyaluronic Acid
The Teosyal line of HA fillers is produced by Swiss company Teoxane Laboratories, a global leader in dermal filler innovation. It is widely regarded as one of the top 3 hyaluronic acid brands in the world, known for rapid effects, long-lasting results, and safety.
Manufactured using Swiss precision engineering, Teosyal is composed of non-animal origin monophasic HA, offering high biocompatibility and low allergenic risk. It not only delivers immediate wrinkle-reducing effects but also boasts extreme moisture retention—capable of absorbing over 1,000 times its weight in water. Its viscoelasticity enables collagen in the skin to form a mesh-like structure, restoring youthful elasticity and firmness.
Teosyal fillers are approved by both the U.S. FDA and European CE, with high purity levels and patented processes that minimize protein and endotoxin content. This significantly reduces the risk of allergic reactions, swelling, or inflammation—making them suitable even for sensitive skin.
Among Teosyal’s extensive product range, the most popular are:
-
Redensity I (for skin rejuvenation)
-
Redensity II, often known as the “Panda Eye Injection” (熊猫针)
-
The TEOSYAL RHA® series, which uses patented technology to preserve the natural properties of HA and mimic the skin’s own hyaluronic acid for dynamic facial areas.
Teosyal is widely used in clinics across Europe, North America, and Asia, including major plastic surgery hospitals in Korea.
JUVÉDERM 乔雅登 Hyaluronic Acid
Often called the “Rolls-Royce of HA fillers,” Juvéderm has over 35 years of experience in producing dermal fillers. Used in more than 100 countries, it has been a global favorite since its launch in 2000. To date, over 100 million syringeshave been sold, making it the #1 brand by global market share.
The Juvéderm family includes five main products:

Utilizing HYLACROSS™ technology, the Ultra and Ultra Plus gels are smooth and homogenous, with no particles. They offer a naturally soft touch, exceptional cohesiveness, and long-lasting lift with low degradation rates.
The V series (Voluma, Volift, Volbella) uses Vycross™ technology, combining short- and long-chain HA molecules for a denser structure that resists free radical breakdown. These fillers can last up to two years and have lower water absorption, offering balanced support and stretch.
-
Volbella excels in lip enhancement with excellent tissue integration and long durability.
-
Volift is ideal for forehead filling with smooth, natural outcomes.
-
Ultra is cost-effective for temples and cheeks due to its strong hydrophilic property, often requiring multiple syringes.
