#3
Best for Dehydration
- Size: 30 ml
- Price per ml: $0.62/ml (original $1.47/ml)
The why
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.
One minus
Sticky, gloopy film can pill under makeup
Good forSensitive Skin
Both recommended for Dehydration.
“Yes! Best advice. I throw on my hyaluronic acid immediately after rinsing my face (wet, not dripping), brush my teeth while it settles, then moisturizer on top. Hydration improved significantly.”
