The serum that stops breakouts before they start

Niacinamide serum dropper

10% Niacinamide (Vitamin B3) tells your skin to produce less oil — fewer clogged pores, fewer breakouts. It's one of the most studied skincare ingredients available, and 10% is the concentration that actually moves the needle.

It also targets the aftermath. The dark spots and red marks left behind after a pimple clears can take months to fade on their own. Niacinamide speeds that up.

  • Best for oily, combination, and acne-prone skin
  • Works for all skin tones — fades hyperpigmentation regardless of skin tone
  • Results typically visible within 4–6 weeks of consistent use
  • Pairs with the Korean Hydrocolloid Patches — patch the breakout, serum prevents the next one

What's inside

Niacinamide (B3)
10% concentration
Reduces oil, minimizes pores, fades dark spots, and strengthens the skin barrier.
Hyaluronic Acid
Hydration booster
Draws moisture into the skin without adding oiliness.
Zinc PCA
Oil control support
Works alongside niacinamide to further regulate sebum production.
Panthenol (B5)
Skin soother
Calms irritation and supports healing after breakouts.

How to use

  • Apply morning and night after cleansing, before moisturizer
  • Use 3–4 drops and gently press into the skin — don't rub
  • Let it absorb before applying other products
  • In the morning, always follow with SPF
  • Use consistently for at least 4 weeks before evaluating results
Pair it: Use the Korean Hydrocolloid Patches overnight on active breakouts, and apply this serum all over after removing the patch in the morning. Two steps. Both problems solved.

How long until I see results?

Most people notice less oiliness within 2–3 weeks. Dark spot fading and pore reduction typically become visible after 4–6 weeks of daily use.

Can I use this with retinol or vitamin C?

Yes. Niacinamide is one of the most compatible skincare ingredients — it layers well with most actives. Apply it before heavier treatments or oils.

Is this safe for sensitive skin?

Yes. The formula is fragrance-free and non-irritating. If you have very sensitive skin, patch test on your inner arm first.

Will this dry out my skin?

No. Unlike benzoyl peroxide or salicylic acid, niacinamide regulates oil without stripping moisture. It's actually hydrating.

My skin is genuinely different

"Three weeks in and my skin is so much less oily by midday. I can't believe a $20 serum is doing what nothing else could."

Finally fading my post-acne marks

"The dark spots from my breakouts have been there for months. After 5 weeks using this serum they're noticeably lighter. Combined with the patches my skin is actually improving."

★★★★★
Light and actually absorbs

"I have oily skin so I always worried serums would make it worse. This one absorbs in seconds, zero residue. My pores look smaller and I'm breaking out way less."
