    Questions

    It doesn't just add surface hydration — it combines three approaches: hyaluronic acid at multiple weights, a PHA that helps skin hold water, and niacinamide to strengthen the barrier, with published improvement in fine lines. It's the serum we use in clinic when dehydration is ageing a client's skin.

    Budget HA serums hydrate the surface, and we stock good ones. This targets how skin retains water over time — boosting your skin's own hyaluronic production rather than only topping it up. If fine lines and persistent dehydration are your concern, the step up is worth it.

    Apply to the whole face and neck morning and evening after cleansing, before moisturiser and SPF. Most clients notice plumper skin within days and softer fine lines over four to six weeks. It suits dry, dehydrated and mature skin especially.
