What the community says

Backed by 3 studies

A multi-weight hyaluronic acid serum with panthenol for damp-skin hydration, especially when tretinoin leaves you tight or flaky. It needs moisturizer over it, and dry climates, compromised barriers, or makeup layering can turn the humectant into irritation and pilling.
