Why moisturise?

Achieving optimal skin hydration is important for both healthy-looking skin and comfort. Dryness in the skin occurs when the skin is producing too little oil, as opposed to dehydration which occurs when there is excessive water loss from the skin. Both oily and dry skins can be dehydrated.

Ultraceuticals moisturisers are designed to tackle dehydration and work to nourish the skin's surface layers. It is important to choose a moisturiser that is suitable for your skin type. Thicker, creamier moisturisers (that contain more oils) are normally recommended for drier skin types, while oilier skin types might prefer lighter lotions (that contain fewer oils).

Our products work best in conjunction with professional treatments.

If you’re currently using corrective serums such as our Ultra A Perfecting Serum or Ultra C Firming Serum, you may layer this serum on top and proceed with your moisturizer and SPF during the day.


What is our Hyaluronic Acid (HA) Complex?

Our new B2 Hydrating serum formulation 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.
