The superpowers of Hyaluronic acid

What Hyaluronic acid does to your skin

Key component of the skin, Hyaluronic acid (HA) is known as one of skincare’s most powerful ingredients for its unparalleled action targeting dryness and dehydration.

Found in our skin, eyes and joints, this molecule is responsible for moisture storage and can hold up to 1000 times its weight in water. Renowned for its ability to attract and lock moisture to the skin, HA is able to instantly plump and smooth.

With the natural aging process and exposure to external aggressors, the amount of Hyaluronic acid in the body can reduce over time. Commonly used as a humectant in serums, water-based moisturising creams and lotions, Hyaluronic acid is also used in injectable dermal fillers to help reduce wrinkles, create structure to the face and add volume to the lips. Hyaluronic acid dermal fillers (also called wrinkle fillers and injectable implants) mimic substances naturally found in our skin.

How Hyaluronic acid rescues dry, dehydrated skin and combats skin aging

Hyaluronic acid is a universal ingredient that suits all skin types, including sensitive, oily or acne-prone skins: this hero ingredient can strengthen the skin’s barrier, has antioxidant properties, as well as healing & repairing action.

Benefits for dry or dehydrated skin

Fast absorbing and non-irritant when acting as a serum or a moisturiser through its water-attracting properties, it benefits dry and dehydrated skin by helping to replenish and hold cell moisture, leading to hydrated, plump skin.

Anti-aging benefits

HA also helps to iron out fine lines and to reduce the appearance of wrinkles since dehydration is one of the main causes of skin aging.

Benefits for oily skin

As they typically leave a minimal emollient residue, HA-based serums or moisturisers are also a good skincare option for oily skins that want to avoid heavy or oil-based skincare whilst keeping moisture levels in balance.

Terrys World molecular weights diagram UK

Skincare & Hyaluronic acid molecular weights explained

Different types of Hyaluronic acids can be used in skincare formulas, and some HA serums or face creams have different molecular weights in their composition.

The molecule sizes of different Hyaluronic acids can vary from low to high (it can range from 5,000 to 20,000,000 Daltons, the unified atomic mass unit). The size of the molecule matters because they will play different roles in the skincare formulas: smaller Hyaluronic acid molecules (with a low molecular weight) can penetrate deeper into the skin’s layer, and bigger molecules sit closer to the skin’s surface.

  • High molecular weights of HA work specifically on the surface & upper layers of the skin preventing dehydration and giving skin a powerful infusion of moisture so it feels hydrated and looks healthier.
  • Medium molecular weights of Hyaluronic acid work on filling, plumping fine lines and wrinkles and smoothing the skin with a deeper action in the epidermis.
  • Low molecular weights of HA penetrate the deeper layers of the skin and work on delivering a more intense, multi-level hydrating action whilst restructuring the skin and improving the overall texture and appearance.

    Terry de Gunzburg explains:

Combining different molecular weights has a proven synergistic effect in the strength of the hydration it delivers, resulting ultimately in a highly superior level of skin nourishment. Blending different hyaluronic acid molecular weights in a cosmetic formula also helps to achieve instant results & long-lasting effects.

Terry’s Signature Ingredient

Pioneer & now leading the way in Hyaluronic-infused makeup, BY TERRY was the first brand to encapsulate Hyaluronic acid in a powder formula.

Fifteen years ago, Terry de Gunzburg took a fingertip portion of pure lyophilised Hyaluronic acid and found herself amazed by this ultra-fine white powder. Fascinated by the lightweight, imperceptible, almost invisible texture, she decided to create an unprecedented product inspired by this raw material. It took years to develop the formula for her now iconic Hyaluronic Hydra-powder, the flagship product of the Hyaluronic range.

The Hyaluronic family now includes tinted and pressed versions of the cult setting powder as well as a primer, a foundation, a concealer and a face cream.

Primer lifestyle

Hyaluronic Hydra-Primer

Why it’s different:

Hyaluronic Hydra-Primer improves the radiance, hold and coverage of any foundation. The secret behind this micro-filler primer lies in its formulation technology exclusively developed by the BY TERRY Research Centre which developed a mousse highly concentrated in Hyaluronic acid. The HA molecules are whipped and fragmented, significantly diminishing their molecular weight, thus enabling them to precisely settle into even the finest lines for a spectacular filler effect.

Similar to miniature water carriers, these molecules expand to lift and smooth wrinkles and fine lines from within (targeting wrinkle volume and depth). The skin is beautifully replumped, appearing more luminous and youthful-looking than ever.

Key benefits:

  • Makeup / Skincare hybrid
  • Blurs imperfections
  • Minimises pores & controls oil
  • Fills fine lines & wrinkles
  • Suitable for all skin types

Terry’s tip: use with your fingers or Tool-Expert Dual ended brush. For a “no makeup makeup” look, mix a small amount of primer to your foundation to lighten coverage and radiance.

How to add Hyaluronic Acid to your beauty routine

HA can be used everyday as part of a skincare or makeup routine, once or twice a day.

Hyaluronic acid enriched serums should be applied on a clean skin, before moisturising.

Because HA works as a moisture magnet, it’s preferable to apply your HA serum, moisturiser or lotion to very slightly wet skin for better results.

BY TERRY’s hyaluronic-infused makeup range is conceived to suit all skin types. Mix & match our Hyaluronic heroes as part of your daily makeup ritual for a truly natural, flawless makeup look.
