How does the dual hyaluronic acid complex in this cream differ from formulas with only one type of hyaluronic acid?

Most hand creams contain a single molecular weight of hyaluronic acid. This formula combines two: high molecular weight HA stays on the skin surface and forms a light, breathable film that reduces the tight feeling after washing or sanitiser use. Low molecular weight HA has smaller particles that penetrate the upper strata of the epidermis, where they bind water and give the skin a fuller, more hydrated appearance. The two work together rather than sequentially — you get immediate surface relief from tightness while the deeper hydration builds over the next hour or two. This is why the product description notes it suits hands that feel "depleted rather than simply needing an occlusive balm." If you have been using a heavy barrier cream that sits on top and feels greasy, this dual-weight approach will feel noticeably lighter while still addressing the underlying moisture deficit.

Practically, apply to clean, slightly damp hands — the residual water gives the HA something to bind immediately. Reapply after each hand-washing or sanitiser use during the day; the film reforms quickly and does not interfere with touchscreens or handling paper.
