Visibly targets post-breakout marks and calms active skin distress

• Calms stubborn redness and active inflammation immediately
• Targets and fades persistent post-blemish marks and spots
• Gently resurfaces skin texture to prevent clogged pores
• Regulates excessive oil production to break the breakout cycle
• Accelerates skin recovery and strengthens the barrier against future flares
• Corrects uneven skin tone by controlling melanin transfer at the source

Calmer. Balanced. Clearer-looking skin — with consistent use.

Apply a small amount to clean, dry skin exclusively at night due to its high-potency formula. Gently spread and allow the serum to fully absorb into blemish-prone areas before layering other products. Always follow with a moisturizer, and ensure you apply sunscreen the following morning.

💡 Pro Tip: Due to the high concentration of 10% Azelaic Acid, slight pilling or a white residue may occur if layered too quickly. For the best results, allow the serum to dry completely before applying your moisturizer.

Q. What makes THOME ABC different from other blemish serums?

A. Instead of relying on a single active, THOME ABC Triple-Synergy Redness Comfort Serum utilizes a Triple-Synergy system. We optimized Azelaic Acid 10%, Niacinamide 5%, and Centella Asiatica 1% to work seamlessly together. This formula delivers comprehensive care—targeting both active redness and post-blemish marks—without compromising gentleness.

Q. Why is Azelaic Acid 10% used in this formula?

A. 10% is a carefully calibrated "sweet spot" that provides powerful benefits while remaining gentle. It visibly fades post-blemish traces and refines uneven skin texture, all while maintaining maximum comfort for sensitive skin.

Q. Can sensitive skin use this?

A. Absolutely. Clinically tested and proven to be non-irritating (0.00 Irritation Index), ABC is formulated specifically for breakout-prone and sensitive skin. It follows a unique "Calm, Balance, and Restore" system to support lasting skin health.

Q. Why is PM use recommended, and what if I see a slight white residue?

A. Because our formula is packed with a highly potent 10% Azelaic Acid, a temporary white residue or pilling may occur if layered too quickly. PM application allows these active ingredients to work undisturbed during your skin’s natural overnight recovery cycle. For the best results, simply allow the serum to dry and absorb completely before applying your next skincare step.
