- Price
- $18.90 · 29.9 ml · $0.63/ml
#2
Best Cheaper Alternative
- Size: 30 ml
- Price per ml: $0.20/ml (original $0.63/ml)

One minus
Can trigger closed comedones or whiteheads
Good forSensitive Skin, Dry Skin
Both recommended for Texture / Pores; discussed alongside Medicube PDRN Pink Peptide Serum in 6 threads.
#3
Same Active: Peptides
- Size: 29.6 ml
- Price per ml: $9.98/ml (original $0.63/ml)
The why
A peptide-and-growth-factor serum built for people chasing firmer, calmer-looking skin and real anti-aging payoff. Redditors with dry, sensitive, or post-procedure skin report visible improvement, but the $300-ish price tag makes it a hard splurge.
One minus
Luxury pricing is brutal
Good forSensitive Skin, Dry Skin
Both recommended for Anti-Aging.

#4
Best for Dehydration
- Key actives: Hyaluronic Acid 2%
- Size: 30 ml
- Price per ml: $0.62/ml (original $0.63/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.
