Hyaluronic acid vs. glycerin: Which is better for your skin?
When it comes to hydration, Hyaluronic Acid (HA) and Glycerin are two of the most popular ingredients in skincare. Both are known for their ability to retain moisture and improve skin health, but they work in slightly different ways. Let’s compare their benefits, uses, and which one might be better suited for your skin needs.
What is Hyaluronic Acid?
Hyaluronic Acid is a naturally occurring molecule in the body, known for its ability to retain water. It acts as a humectant, drawing moisture from the environment into the skin.
Benefits of Hyaluronic Acid:
- Intense Hydration: Retains up to 1,000 times its weight in water, deeply hydrating the skin.
- Plump Skin: Fills in fine lines and wrinkles, giving a youthful look.
- Non-Greasy: Lightweight and absorbs quickly into the skin.
- Boosts Elasticity: Improves skin firmness and smoothness.
Best For:
- Dry, dehydrated, or mature skin.
- All skin types, due to its lightweight, non-comedogenic properties.
What is Glycerin?
Glycerin is a naturally derived compound that also acts as a humectant, pulling moisture into the skin. It is a versatile ingredient found in many skincare products.
Benefits of Glycerin:
- Deep Moisturisation: Attracts and locks moisture into the skin.
- Repairs Skin Barrier: Strengthens the skin’s natural barrier, preventing water loss.
- Gentle and Safe: Suitable for sensitive skin and all ages.
- Improves Texture: Leaves skin soft, smooth, and supple.
Best For:
- Extremely dry or damaged skin.
- Sensitive skin types needing gentle hydration.

Can You Use Both Together?
Yes! Hyaluronic Acid and Glycerin work beautifully together. While HA attracts moisture to the skin’s surface, Glycerin locks it in, providing long-lasting hydration.
How to Layer Them:
- Apply a Hyaluronic Acid serum to damp skin to draw in moisture.
- Follow with a product containing Glycerin (e.g., moisturiser) to seal hydration.
Which Should You Choose?
Choose Hyaluronic Acid If:
- You need lightweight hydration without greasiness.
- You have oily, acne-prone, or combination skin.
- You’re looking for an anti-ageing boost.
Choose Glycerin If:
- You have very dry or sensitive skin needing barrier repair.
- You want an affordable, all-purpose hydrator.
- Your skin is damaged or flaking due to environmental stressors.
Final Verdict
Both Hyaluronic Acid and Glycerin are excellent hydrating ingredients, and the best choice depends on your specific skin needs. HA is ideal for lightweight hydration and plumping, while Glycerin excels at repairing the skin barrier and retaining moisture. Combining both in your routine can maximise their benefits, ensuring soft, smooth, and well-hydrated skin.
