Most effective Hyaluronic Acid
High molecular weight
High molecular weight hyaluronic acid is the much larger variant as per outlined in the table above. It consists of molecules of 1,500 kD and larger and cannot penetrate the skin barrier. However, it forms a film with the keratin of the skin on evaporation, which moisturizes the skin and improves its elasticity. Unfortunately, this film is washed off relatively quickly, so that no real long-term effect occurs. Finally, this type has anti-inflammatory properties. So it is quite nurturing and soothing.
Low molecular weight
Low molecular weight hyaluronic acid makes it possible to enter the skin. It consists of molecules of 50 kD and smaller and ensures that water is stored in the connective tissue of the skin. The additional moisture not only makes the skin more firm and firmer, but also visibly reduces wrinkles. When using low molecular weight hyaluronic acid, the moisture is stored in the skin sustainably. Therefore, it has more advantages and above all a more lasting effect.
Recent independent research have outlined that the hyaluronic you want to use should be between 80,000 to 1,000,000 daltons (80 – 1,000 kDa). See reference to refer to the research. Thus, this seems to be the most effective molecular size that supports the skin to maintain its moisture and elasticity according to studies. Anything higher won’t do much good and has a short-lived effect that is getting removed after you cleanse your face. Anything lower might cause inflammation if used in too high dose as it penetrates deep into your skin. So one needs to carefully formulated with those and leave it to experts with years of experience.
Hyaluronic Acid & Medicine
In medicine, e.g. hyaluronic acid is used as joint injection for lubrication and padding of joints. In many eye drops, it is included as a wetting agent for contact lenses or for the treatment of dry, irritated eyes. In aesthetic surgery, it is also used as a skin filler to make wrinkles disappear for a few months. Hyaluronic acid is certainly an ingredient that is popular in premium products that focus on more mature skin. However, it is never to late to start using hyaluronic acid.
In general, formulations do not include more than 2% and is indicated by manufacturer to ensure safe usage. This indication is based on testing and safety assessments conducted by independent parties.
The best way to use a hyaluronic acid serum
Though hyaluronic acid can attract and retain moisture, it doesn’t necessarily keep that moisture from evaporating over time. That’s why it’s important to maximize the benefits by adding an occlusive or emollient ingredient into your routine, like a face oil. It seals in the moisture drawn into skin by the hyaluronic acid, and the two work together to ensure skin is both hydrated and stays that way.
To offset this inevitable moisture loss — and therefore minimize dryness, lines and wrinkles, and other signs of ageing — it is important to incorporate it into your daily routine to ensure you can reap all of the benefits.
