THOME Azelaic Acid Serum 10% + Niacinamide 5% — 1.01 fl oz, Redness-Soothing & Oil-Balancing

THOME ABC Serum is a targeted 10% azelaic acid, 5% niacinamide, and 1% centella asiatica blend designed to refine texture, balance oil, and soothe visible redness in one daily serum.

This lightweight Korean-inspired serum uses the brand’s precision "ABC Mechanism" to combine high-strength clarifying actives with calming botanicals. Rather than relying on a single ingredient, THOME balances potent azelaic acid and niacinamide with centella asiatica to help manage oiliness, improve the appearance of post-blemish marks, and support a less reactive-looking complexion. The 1.01 fl oz dropper-style bottle delivers a concentrated treatment suitable for layering under moisturizer and sunscreen.

How will this serum affect excess oil and shine throughout the day?

The formula’s 5% niacinamide works to regulate sebum appearance and promote a more even skin surface, while 10% azelaic acid adds pore-clarifying support. Together they aim to help skin look less shiny and feel less congested without over-drying.

• 5% niacinamide to help visibly balance excess oil production.
• 10% azelaic acid to assist in reducing bumps and congestion.
• Lightweight texture for easy layering under mattifying products.

Can this serum reduce redness and calm sensitive-looking skin?

Centella asiatica at 1% acts as a calming buffer in the blend, helping to comfort stressed-looking skin while the actives work. The combined approach reduces the need for multiple separate treatments, offering a simpler routine for sensitive-prone complexions.

• 1% centella asiatica to soothe visible redness and support barrier comfort.
• Balanced concentrations to minimize irritation risk compared with single high-dose actives.
• Suitable for layering with gentle hydrators to further reduce reactivity.

What improvements to texture and post-blemish marks can I expect?

Azelaic acid at 10% is included for its texture-refining properties; over consistent use it aims to smooth rough areas and help fade the look of post-blemish discoloration. Niacinamide complements this by promoting a more uniform tone and helping skin appear clearer overall.

• 10% azelaic acid to visibly refine uneven texture and reduce roughness.
• Niacinamide to support tone correction and clearer-looking skin.
• Daily application helps maintain improvements alongside sunscreen use.

How should I incorporate THOME ABC Serum into my routine?

Apply a few drops to clean, dry skin after cleansing and before thicker serums or moisturizer. Use once daily at first or every other day if you have very reactive skin, then increase frequency as tolerated. Always finish daytime use with broad-spectrum sunscreen.

• Use after cleansing and light toning, before creams.
• Start every other day if you’re new to azelaic acid, then move to daily use.
• Pair with SPF in the morning to protect improved texture and tone.

Who is this for: THOME ABC Serum is designed for people seeking a streamlined treatment that addresses multiple visible concerns—excess oil, uneven texture, post-blemish marks, and noticeable redness—without a complicated multi-step regimen. It’s a practical choice for combination, oily, blemish-prone, and redness-prone skin types who want a single, targeted serum to add to their daily routine; those with highly reactive or medically sensitive skin should patch-test and consult a dermatologist if concerned.
