#1
Best Overall Alternative
- Size: 50 ml
The why
A beta-glucan and glycerin humectant serum for dehydrated, tret-irritated skin, applied to damp skin before moisturizer. It layers neatly for many users, but acne-prone or rosacea-prone skin can face breakouts, heat, stinging, or redness.
One minus
Breakouts and closed comedones show up for some users
Good forDry Skin, Sensitive Skin
Both recommended for Redness / Irritation.
“Been using beta glucan serum for like 6 months now and it's really good for the irritation from tret.”

Skin1004·Serum
See alternativesFeatherlight, watery texture; layers cleanly under makeup
- Size: 30 ml
The why
A watery centella-and-glycerin ampoule for calming redness and adding light hydration around tretinoin or acids. It suits sensitive, oily, or combination skin, but dry skin may need moisturizer and acne-prone users report closed comedones.
One minus
Closed comedones and cystic breakouts hit some users
Good forSensitive Skin, Dry Skin
Both recommended for Redness / Irritation.
“But when my rosacea flare up was at its worst (even water stung my skin), it’s the only product that soothed my skin.”
— Reddit, r/AsianBeauty
#3
Best for Skin Barrier
- Size: 45 ml
The why
A creamy, oil-rich barrier serum with 10% tamanu oil, niacinamide, ceramide NP, and humectants, built for stripped, dry skin and tretinoin routines. Redditors call it HG, but acne-prone users report burning, hives, or breakouts; studies find niacinamide’s acne results uncertain.
One minus
Burning can persist until you stop it
Good forSensitive Skin, Dry Skin
Both recommended for Redness / Irritation.
