Question 1

What makes this different from other hyaluronic acid serums?

Accepted Answer

It combines three molecular weights of hyaluronic acid, so it hydrates at different depths of the skin rather than just sitting on the surface. The result is visibly plumper, bouncier skin — at €24 it's one of the best-value hydrating serums we stock.

Question 2

How do I apply a hyaluronic acid serum correctly?

Accepted Answer

Apply a few drops to slightly damp skin after cleansing and toning, then seal immediately with moisturiser — hyaluronic acid draws water, so it needs moisture to pull from and a cream to lock it in. Use morning and evening.

Question 3

Can I use hyaluronic acid with retinol, vitamin C or acids?

Accepted Answer

Yes — hyaluronic acid is the universal team player. It buffers stronger actives, reduces irritation, and layers safely with everything, making it ideal alongside retinoids or exfoliating acids. It's fragrance-free and suits all skin types, including sensitive.

Question 4

Will hyaluronic acid help oily skin?

Accepted Answer

Yes. Oily skin is often dehydrated skin overproducing oil to compensate. A lightweight water-based HA serum hydrates without any richness, which over time can help rebalance how oily your skin feels through the day.
