AESTURA A-Cica 365 Soothing Relief Serum pH4.5: The Dermatologist-Tested Barrier Serum

AESTURA is Amorepacific's dermatologist-facing brand, recommended in Korean clinics as an adjunct to procedure recovery and prescription retinoid routines. The A-Cica 365 Serum is their daily soothing serum, built around a patented Madecassoside complex and formulated to the slightly acidic pH 4.5 that matches healthy skin. At 40ml for $43.90, it's priced at the upper end of the drugstore tier but below cosmeceutical competitors like Dr.Jart+ Cicapair.

The A-Cica line exists because AESTURA wanted a year-round serum that wouldn't fight with other actives in a full routine. Most soothing serums read as one-note (just centella), but this one layers low-molecular-weight hyaluronic acid, panthenol, and allantoin alongside the Madecassoside. The result is a serum that calms without leaving skin needy for additional hydration layers.

What It Does

Madecassoside is the most studied fraction of Centella asiatica, with clinical data supporting it as an inflammation reducer and collagen support. At pH 4.5 the skin barrier stays calm (rather than being nudged toward alkaline imbalance), and the formula absorbs fast enough to layer under sunscreen in the morning. This is a daily maintenance serum, not a dramatic-transformation product.

Who It's For

• Sensitive or reactive skin: Low-allergen formula tested on 1,000+ sensitive-skin users.
• Post-procedure or post-retinol recovery: Safe to layer after lasers, peels, or retinoid flare-ups.
• Rosacea-prone or redness-prone skin: Madecassoside reduces visible redness over 4 to 6 weeks.
• Oily skin that gets irritated easily: Light texture that doesn't trigger breakouts.
• Everyday maintenance users: A sensible year-round serum without drama.

FAQ

Is this better than Dr.Jart+ Cicapair?

Different approach. Cicapair leans heavier (cream consistency, tiger grass complex) and is better as a finishing layer. AESTURA A-Cica 365 is a serum format that slots into a fuller routine. For one product only: Cicapair. For layered skincare: A-Cica 365.

Can I use this on broken or peeling skin?

Yes. Madecassoside supports wound healing and the formula is free of fragrance, essential oils, and drying alcohols. Clinics in Korea recommend AESTURA for post-laser recovery.

How long until I see redness reduction?

Immediate calm: within hours of application. Visible baseline redness reduction: 4 to 6 weeks of twice-daily use. Chronic rosacea requires dermatologist supervision alongside any topical.

Does it conflict with vitamin C or retinol?

No. The pH 4.5 is compatible with vitamin C (optimal at pH 3.5 to 4) and retinoids. Sequence: vitamin C first (AM), then A-Cica 365, then moisturizer, then SPF. In PM: retinol first, let absorb, then A-Cica 365, then cream.

Is it fragranced?

No added fragrance. Clean-smelling with mild natural scent from the extracts. Tested for hypoallergenic performance on sensitive-skin panels.
