Why it works
HA 5 Rich is a silky, richer hydrating serum with five forms of hyaluronic acid to support water-binding, softness and a plumper-looking skin feel.
Multi-form hydration
Five forms of hyaluronic acid help bind water at different surface levels of the skin. This supports a softer, smoother and more hydrated feel.
Surface moisture support
Larger and cross-linked hyaluronic acid forms support surface hydration. Skin feels plumper, more comfortable and less tight.
Richer comfort support
Tremella mushroom extract, panthenol, betaine and glycerin add extra hydration and comfort. This gives the serum a silkier, richer feel than a lighter hydration serum.
Key Ingredients
5 Forms of Hyaluronic Acid
A multi-form hydration system that helps bind water at different surface levels of the skin. Larger and cross-linked HA forms support surface plumpness and longer-lasting hydration, while smaller HA forms help skin feel softer, smoother and more comfortable.
Tremella Fuciformis Mushroom Extract
A water-binding mushroom extract with a lightweight, non-sticky feel. It adds hydration support and helps skin feel softer and more comfortable.
Betaine
A water-binding ingredient that supports the richer hydrating base of the formula. It helps skin feel soft, smooth and comfortable without making the serum heavy.
Panthenol
A hydrating and skin-conditioning ingredient that supports comfort. It helps reduce the feeling of tightness and keeps the formula gentle-feeling.
How to use
Apply a few drops to the face morning and/or evening before moisturiser. Use it as a richer hydration step, or blend a few drops into your moisturiser if you prefer a simpler routine. Follow with cream to help seal in hydration.
FAQ
What does HA 5 Rich do?
HA 5 Rich gives the skin rich, water-based hydration without acting like a heavy cream. It combines five forms of hyaluronic acid with Tremella mushroom extract, betaine, panthenol and glycerin to help bind moisture at the skin’s surface, soften tightness and make the skin look smoother and more plump. The richer serum texture makes it especially useful for normal to dry skin that wants more comfort from a hydrating serum.
How does hyaluronic acid work in the skin?
Hyaluronic acid is a humectant, which means it helps attract and bind water. In skincare, it works mainly in the upper layers and surface of the skin, where it supports hydration and reduces the feeling of tightness. Different forms of hyaluronic acid can support hydration in slightly different ways: larger forms help create a plumper-looking surface, cross-linked forms help hold water for longer on the skin, and smaller forms support a softer, more comfortable feel.
Who is HA 5 Rich best for?
HA 5 Rich is suitable for all skin types, but it is especially suited to normal and dry skin. It is a good option if your skin feels dehydrated, tight, dry or in need of a silkier hydration layer.
Should I choose HA 5 Rich or HA 5 Light?
Choose HA 5 Rich if your skin is normal to dry, dehydrated or tight and you prefer a silkier, richer serum texture. Choose HA 5 Light if your skin is normal, combination or oily and you prefer a lighter, fast-absorbing hydration step.
Can I use HA 5 Rich every day?
Yes, HA 5 Rich can be used morning and/or evening. Apply it before moisturiser, or mix a few drops into your cream.
Can I use HA 5 Rich with active ingredients?
Yes, HA 5 Rich is a hydrating serum and can fit easily into routines with other skincare products. Use it before moisturiser to add hydration and comfort without adding exfoliating or strong active treatment activity.
Is HA 5 Rich pregnancy-safe?
Yes, HA 5 Rich is pregnancy-safe. If you are breastfeeding or unsure, check with your healthcare provider before use.
