#1
Best Overall Alternative
- Size: 29.9 ml
- Price per ml: $0.69/ml (original $1.45/ml)
The why
A creamy 0.1% retinol serum with retinal, niacinamide, panthenol, and ceramide NP for first-time retinoid users easing into nighttime treatment. It suits sensitive beginners, but fragrance and occasional dryness mean reactive or dehydrated skin should start once weekly.
One minus
Results can be subtle or nonexistent for some users

#2
Best Cheaper Alternative
- Key actives: Retinol 0.5%
- Size: 29.6 ml
- Price per ml: $0.31/ml (original $1.45/ml)
The why
A 0.5% retinol oil with squalane and jojoba oil targets texture and acne. Redditors report clearer pores, and research found retinol reduced pimples and sore spots; irritation and breakouts make it a poor match for sensitive skin.
