What is Hyaluronic Acid in Skincare: Benefits, Uses & How to Choose (Singapore Guide)?
Hyaluronic acid is a naturally occurring sugar molecule found in the skin, joints, and connective tissues. Its primary role is to bind water, each molecule can hold up to 1,000 times its weight in moisture.
As we age, or when skin is exposed to environmental stressors such as UV exposure, air-conditioning, or frequent treatments, the skin’s natural hyaluronic acid levels decline. This leads to dehydration, loss of elasticity, and the appearance of fine lines.
When used topically in skincare, hyaluronic acid helps replenish hydration at the skin’s surface, improving skin smoothness, suppleness, and overall comfort.
Where it comes from
In skincare formulations, hyaluronic acid is typically produced through bio-fermentation. This process creates a stable, skin-compatible form of hyaluronic acid that is suitable for daily topical use.
Different molecular weights of hyaluronic acid may be used in professional formulations to support hydration at various levels of the skin’s surface.
How it works on skin
Hyaluronic acid works by attracting water molecules to the skin and holding them in place. When applied to slightly damp skin and sealed with a moisturiser, it helps reduce transepidermal water loss and supports a healthier skin barrier.
Well-formulated hyaluronic acid products can improve the appearance of fine lines caused by dehydration and enhance skin smoothness without clogging pores or leaving a greasy residue.
