#1
Best Overall Alternative
- Size: 149.9 ml
- Price per ml: $0.10/ml (original $0.98/ml)
The why
A watery peptide-and-niacinamide first layer that hydrates damp skin, softens rough texture, and helps subsequent products spread cleanly. It suits oily, combination, and tretinoin users wanting low-maintenance cushioning, though some see only mild hydration and others report breakouts or flushing.
One minus
Results can stop at mild hydration and a little glow
Good forDry Skin, Sensitive Skin
Both recommended for Redness / Irritation.

#2

The why

- Size: 30 ml
- Price per ml: $0.20/ml (original $0.98/ml)
The why
A watery Centella Asiatica Extract serum with Glycerin, built for redness, irritation, and recovery nights around tretinoin. Sensitive, rosacea-prone users often love its quick layering; acne-prone skin can develop closed comedones or cystic breakouts.
One minus

#4
Best for Texture / Pores
- Size: 50 ml
- Price per ml: $0.69/ml (original $0.98/ml)
The why
This is a niacinamide serum, used as step zero before your routine. Redditors reach for it for glow and texture, while studies find niacinamide’s acne results uncertain; sensitive skin may face stinging, redness, or breakouts.
One minus
Breakouts and closed comedones are recurring complaints
Both recommended for Texture / Pores.
