Everything You Need to Know About Hyaluronic Acid
Hyaluronic acid is one of the most talked-about ingredients in skincare — and for good reason. Naturally present in the skin, it acts as a powerful moisture magnet, holding up to 1,000 times its weight in water to keep the skin hydrated, plump, and youthful. Here’s everything you need to know.
What Is Hyaluronic Acid?
Hyaluronic acid (HA) is a naturally occurring glycosaminoglycan found in the skin’s connective tissue. Its primary function is moisture retention — it binds to water molecules and keeps the skin’s deeper layers lubricated, supple, and well-hydrated.
As we age — and as a result of UV exposure, pollution, and environmental stress — our natural HA levels decline. The result is drier, less elastic skin with more visible fine lines and wrinkles.
Key Benefits of Hyaluronic Acid
- Deep, lasting hydration — draws moisture into the skin and holds it there throughout the day
- Plumps and firms — improves skin elasticity, reducing the appearance of fine lines
- Anti-aging action — replenishes declining HA levels to restore a more youthful appearance
- Soothes and calms — reduces inflammation and supports the skin barrier in reactive or acne-prone skin
- Supports skin repair — assists in wound healing by regulating inflammation and improving tissue response
- Compatible with all skin types — lightweight and non-comedogenic; suitable for oily, dry, sensitive, and combination skin
Hyaluronic Acid vs. Sodium Hyaluronate
You’ll often see Sodium Hyaluronate listed on product ingredients rather than Hyaluronic Acid. Sodium Hyaluronate is a salt derived from HA with a slightly lower molecular weight — meaning it penetrates the skin more easily. Both are effective; the best formulas use both for surface and deep hydration simultaneously.
How to Use Hyaluronic Acid
Apply HA to damp skin — it works by drawing moisture from the environment into the skin, so applying to slightly wet skin maximises its effect. Layer it under your moisturiser to seal in hydration. It can be used morning and evening.
HA pairs well with Vitamin C, retinol, AHAs, and BHAs — in fact, pairing it with retinol or exfoliating acids helps offset their potential dryness and irritation.

Frequently Asked Questions
Does hyaluronic acid really work?
Yes — it is one of the most clinically validated skincare ingredients available. Its moisture-binding properties are measurable and its effects on hydration, elasticity, and skin appearance are well-documented.
Is there any side effect?
Hyaluronic acid is well-tolerated by virtually all skin types with no significant known side effects. As with any new ingredient, a patch test is recommended.
Glycolic acid or hyaluronic acid — which is better?
They serve different purposes. Glycolic acid exfoliates and targets ageing; hyaluronic acid hydrates and plumps. They work well together — use glycolic in the evening and HA in the morning, or layer HA after applying glycolic to buffer irritation.
Can you use hyaluronic acid with Vitamin C?
Yes — they complement each other well. Vitamin C brightens and protects while HA hydrates. Apply Vitamin C first, followed by HA serum, then moisturiser.
Can you use retinol and hyaluronic acid together?
Yes, and it’s recommended. Hyaluronic acid counteracts the dryness that retinol can cause, making the combination more comfortable and effective.
Is hyaluronic acid good for oily skin?
Yes — HA is lightweight and non-comedogenic. It provides hydration without adding oil or clogging pores, making it ideal for oily and combination skin.
Can hyaluronic acid cause acne?
No. HA does not trigger acne and is suitable for acne-prone skin. Its anti-inflammatory properties may actually help calm active breakouts.
Can I use hyaluronic acid every day?
Yes — it is gentle enough for twice-daily use, morning and evening, as a core step in any skincare routine.
