What You Need To Know

Ultraceuticals Corrective Serums are designed to be used with your daily essential products such as cleansers, moisturisers, and sun protection. This is to ensure that our highly efficacious correctors are used with products that contain ingredients to help complement and support healthy skin daily.

B² Hydrating HA 360 Facial Serum features a combination of Niacinamide (vitamin B3) and Panthenol (provitamin B5) to dramatically improve the appearance of dehydrated, dull and coarse skin texture to a softer, smoother and more supple complexion.

Our B² Hydrating HA 360 Facial Serum contains Triple-HA Complex, a blend of 3 forms of HA (hyaluronic acid).

When it comes to Hyaluronic Acid, size does matter! Its benefits and absorption depend on molecular weight and structure.

Our selected forms of Hyaluronic Acids will travel to different skin layers, it goes 5 layers deep to boost & retain hydration, enhance skin plumpness and visibly improve fine lines and wrinkles.

  • HA-Macro - high molecular weight, it’s larger in size and sits on the skin’s surface, acting like a “sponge” that holds up to 1000 times its weight in water.
  • AC-Hyal – small molecule known as super hyaluronic acid, features a unique structure that firmly adheres to deep skin layers. This ensures not just intense hydration but also long-term visible results in plumpness, firmness and improvement of fine lines and wrinkles.
  • HA-Micro - low molecular weight, it’s a very small in size and easily absorbed into deeper skin layers to increase hydration and improve firmness.
