Beta-glucan hydration for tret-dried skin; reformulation complaints and breakouts persist.

What the community says

A short-list beta-glucan and glycerin humectant serum for damp-skin hydration, especially when tretinoin leaves skin tight or flaky. It layers easily, but acne-prone or rosacea-prone users report breakouts, stinging, and weaker hydration after reformulation.
