NIACINAMIDE 21 PORE SERUM 50ml

Korea's highest concentration: 21% niacinamide for pore care

A pore-targeting serum powered by 21% high-concentration niacinamide. It helps control sebum to visibly reduce whiteheads and refine rough, uneven texture into a smoother finish. To offset the dryness that can come with high-dose powder actives, we've balanced the formula with hyaluronic acid and hydrating ingredients for a comfortable, silky glide. This product is also certified by the Korean Ministry of Food and Drug Safety as a functional cosmetic for wrinkle improvement.

Visible pore improvement confirmed after 2 weeks of use

In a clinical study conducted by the Korea Institute of Dermatological Sciences on 21 adult women aged 43–64, the following improvements were observed after 2 weeks of use.

• Whiteheads (sebum): 51.32% improvement
• Pore area: 23.29% improvement
• Pore volume: 31.47% improvement
• Pore depth: 17.41% improvement
• Pore count: 17.85% improvement

The formula also passed a hypoallergenic patch test on sensitive skin and received a non-irritating rating.

A multi-tasking formula from sebum control to tone evening

Beyond niacinamide (sebum control, tone correction), the serum includes zinc PCA (oil control), acetyl glucosamine (radiance boost), elm bark extract (pore tightening), and green tea water (moisture replenishment). Ideal for those with enlarged pores and excess sebum, anyone concerned with a dull complexion, or those seeking firmer, more refined skin texture. After toner, dispense an appropriate amount and smooth gently along the skin's texture, then pat lightly to help absorption.

Use after toner, during the essence step

This is a serum designed to be applied right after toning, once your skin texture is prepped. With a high-concentration formula of 21% niacinamide, it targets pores and skin texture, so let it absorb fully before layering on your hydrating essence or moisturizer. When paired with your usual moisturizing products, you'll notice a synergistic boost.

Suitable for both morning and evening

You can incorporate this into both your AM and PM routines. If using in the morning, always finish with sunscreen as your final step. In the evening, it works in harmony with your skin's natural renewal cycle to refine pores and even out tone.

One pump covers the entire face

Dispense about one pump into your palm and gently smooth it over your face, following the natural texture of your skin. Pay a little extra attention to areas where pores are more visible, like around the nose and cheeks, then lightly pat with your palms to help it sink in.

Routine pairing tips by skin concern

• For pores and excess oil: Follow a lightweight toner with this serum, then seal with a fresh, hydrating moisturizer
• For dull complexion: Alternate with vitamin C by using vitamin C in the morning and this serum at night to avoid overlap
• For firmness support: Layer a peptide cream over this serum to amplify elasticity benefits

How to care for a high-concentration formula

While this product has completed sensitivity testing for gentle use, if you're new to high-dose niacinamide, we recommend doing a patch test on your inner arm before full application. You may notice a white powder around the dispenser opening—this is a natural characteristic of powdered raw materials and nothing to worry about. Best used within 12 months of opening. Store in a cool place away from direct sunlight.
