#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 alternativesCentella-focused seven-ingredient formula
- Size: 30 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
Closed comedones and cystic breakouts hit some acne-prone 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 serum with 10% tamanu oil, niacinamide, ceramide NP, and fatty acids for stripped, reactive skin. Redditors call it an HG barrier step, while studies found niacinamide’s acne results uncertain; tamanu can still trigger breakouts.
One minus
Tamanu oil breaks some acne-prone users out
Good forSensitive Skin, Dry Skin
Both recommended for Redness / Irritation.
