#2
Best Cheaper Alternative
- Size: 29.6 ml
- Price per ml: $0.20/ml (original $0.65/ml)
The why
A simple sodium hyaluronate serum for layering onto damp skin before moisturizer, especially when tretinoin leaves dehydration lines. It can feel tight or worsen dryness in arid conditions unless sealed promptly, and some users report bumps or clogged pores.

Can leave skin tighter instead of hydrated
Good forDry Skin
Both recommended for Dehydration.

See alternativesWatery toner-like texture; layers under everything
- Size: 150 ml
- Price per ml: $0.12/ml (original $0.65/ml)
The why
A watery peptide-and-niacinamide first layer that hydrates damp skin, reduces post-cleanse tightness, and helps subsequent products spread smoothly. It fits oily, combination, and tretinoin routines, though rosacea-prone users report flushing and some finish bottles unimpressed.
One minus
Peptide results can be imperceptible after a full bottle
Good forDry Skin, Sensitive Skin
Both recommended for Dehydration.
“It prevents that tight, dry feeling between cleansing and the rest of my routine, absorbs super quickly, and helps everything else layer smoothly.”
— Reddit, r/AsianBeauty
#4
Best for Dehydration
- Key actives: Hyaluronic Acid 2%
- Size: 30 ml
- Price per ml: $0.62/ml (original $0.65/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.
