#1
Best Overall Alternative
- Key actives: Azelaic Acid 10%
- Size: 30 ml
- Price per ml: $0.62/ml (original $0.36/ml)
The why
A 10% azelaic acid serum with sodium hyaluronate, panthenol, and ceramide NP, aimed at acne, redness, and post-acne marks. Studies support azelaic acid for acne, and Redditors report calming; reactive or barrier-damaged skin can sting or break out.
One minus

Good forSensitive Skin, Dry Skin
Both recommended for Dehydration.

#2
Best Cheaper Alternative
- Size: 29.6 ml
- Price per ml: $0.20/ml (original $0.36/ml)
The why
A minimalist hyaluronic acid serum for adding water-based hydration before moisturizer, especially when dehydration lines are the problem. Apply to damp skin and seal promptly; very dry climates can leave some users tighter, and it will not replace moisturizer.
One minus
Can leave skin tighter or drier when not sealed promptly
Good forDry Skin
Both recommended for Dehydration.

- Price per ml: $0.38/ml (original $0.36/ml)
The why
A water-light humectant serum with multiple hyaluronic acid forms adds quick hydration without sticky residue. Best on damp skin for dehydrated, oily, or combination complexions; dry climates may need moisturizer on top, and reactive skin can sting.
One minus

Good forSensitive Skin, Dry Skin, Oily Skin, Combination Skin
Both recommended for Dehydration.

Beta-Glucan Power Moisture Serum
iUNIK·Serum
See alternativesBeta-glucan visibly plumps dehydration lines
- Size: 50 ml
- Price per ml: $0.27/ml (original $0.36/ml)
The why
A short-list beta-glucan and glycerin humectant serum for damp-skin hydration, especially when tretinoin leaves skin tight or flaky. It layers easily, but acne-prone or rosacea-prone users report breakouts, stinging, and weaker hydration after reformulation.
One minus
Breakouts and whiteheads show up for some users
Good forDry Skin, Sensitive Skin
Both recommended for Dehydration.
