#2
Best Cheaper Alternative
- Size: 29.6 ml
- Price per ml: $0.20/ml (original $0.33/ml)
The why
A basic hyaluronic acid serum with glycerin and sodium hyaluronate that people use after cleansing, often on damp skin, before moisturizer. It suits dehydrated or retinoid-dry skin. In very dry air or without an occlusive, it can feel tight or even backfire.
One minus
Needs a moisturizer or occlusive on top
Both recommended for Dehydration.
#3
Same Active: Hyaluronic Acid
- Key actives: Hyaluronic Acid 2%
- Size: 30 ml
- Price per ml: $0.62/ml (original $0.33/ml)
The why
A hyaluronic acid serum with panthenol and glycerin that people mainly use for dehydration and post-retinoid tightness. Best on damp skin under moisturizer, especially if your barrier is cranky. Dry climates and heavy layering can make it feel sticky or useless.
One minus
Sticky, tacky, and prone to pilling
Good forDry Skin, Sensitive Skin
Both recommended for Dehydration.
