What Is Hyaluronic Acid: Benefits, How It Works & Best Products to Add to Your Routine
Hyaluronic acid (HA) has become a skincare staple – and for good reason. Loved by dermatologists and beauty enthusiasts alike, this powerful humectant locks in moisture, smooths fine lines, and boosts skin health. In this post, we’ll explain what hyaluronic acid is, how it benefits your skin, and which Amazon skincare products are worth adding to your routine.
What Is Hyaluronic Acid?
Hyaluronic acid is a naturally occurring molecule found in your skin, joints and connective tissues. Its main superpower? Hydration. It can hold up to 1,000 times its weight in water, helping skin retain moisture and stay plump and soft.
Although your body produces HA naturally, levels decline with age – which can contribute to dryness and loss of firmness. Topical HA in serums and moisturisers helps counteract that by drawing moisture into the skin’s surface.
How Hyaluronic Acid Affects Your Skin
Here’s a breakdown of the key ways HA benefits your skin:
Deep Hydration & Moisture Retention
HA acts like a moisture magnet. It pulls water into the skin’s outer layer, helping to keep it hydrated and supple throughout the day.
Plumps and Smooths Fine Lines
Hydrated skin looks smoother and more youthful. HA plumps the skin’s top layers, making fine lines and dryness less noticeable.
Supports the Skin Barrier
By improving hydration and strengthening the skin’s lipid barrier, HA helps protect against environmental stressors like pollution and dryness.
Works for Most Skin Types
Hyaluronic acid is lightweight, often non-irritating, and suitable for dry, combination, oily, and sensitive skin – making it a versatile choice for many skincare routines.
How to Use Hyaluronic Acid in Your Routine
- Apply on damp skin: For best results, use HA after cleansing and toning while your skin is still slightly damp – it helps the ingredient draw in water more effectively.
- Layer under moisturiser: Seal in moisture with a richer cream or moisturiser after your HA serum.
- Use both morning and night: Twice-daily application keeps skin hydrated and radiant.
