Parnell AHA 9.12 Omija Ceramic Wash-Off Serum 30ml: Short-Contact AHA Treatment with Omija

Parnell is a Korean dermocosmetic brand with growing international following for ingredient-forward formulations. The AHA 9.12 Omija Ceramic Wash-Off Serum is a treatment exfoliant using 9.12% alpha hydroxy acids (glycolic, lactic, or a blend) alongside Omija (Schisandra chinensis, a traditional Korean adaptogenic berry) extract. The "ceramic" naming likely references the smooth, refined finish after use. At $27.51 for 30ml, pricing is fair for a treatment exfoliant.

Wash-off AHA treatments are the compromise between daily leave-on acids (which require skin adjustment) and professional chemical peels (which need downtime). You apply the product, leave on for 3 to 10 minutes, then rinse. This short-contact approach provides meaningful exfoliation with manageable irritation. Weekly or twice-weekly use over 8 to 12 weeks shows measurable texture improvement.

What It Does

AHA 9.12% provides strong surface exfoliation by dissolving intercellular "glue" between dead skin cells. Omija (Schisandra) extract offers antioxidant defense and traditional adaptogenic benefits. The wash-off format limits contact time, reducing irritation while delivering meaningful effect. Post-use, skin feels smoother, looks brighter, and has refined texture. Not for sensitive skin beginners.

Who It's For

• Texture and tone refinement users: Primary target.
• Users who want treatment effect without daily leave-on: Short-contact approach.
• Post-acne scar softening: AHA supports gradual smoothing.
• Normal to combo skin: Robust enough for strong AHA.
• Korean dermocosmetic fans: Parnell fits this profile.

FAQ

Is 9.12% AHA too strong for beginners?

Yes. For AHA-naive skin, start with a lower concentration (5% or less) daily product first, build tolerance for 4 to 6 weeks, then introduce this wash-off.

How long to leave it on?

Start with 3 minutes the first use, monitor for burning/excessive redness. If tolerated, increase by 1 to 2 minutes each session up to 10 minutes maximum. Don't leave longer than 10 minutes.

Will it sting?

Mild tingling is normal. Sharp burning or painful sting means remove immediately and neutralize with water. If that happens, your skin isn't ready for this concentration; try gentler AHA first.

Parnell vs The Ordinary AHA 30% BHA 2% Peel?

The Ordinary is more aggressive (30% AHA + 2% BHA). Parnell at 9.12% is more accessible and can be used weekly. For strong dramatic exfoliation, The Ordinary. For weekly maintenance exfoliation, Parnell.

How long does 30ml last?
