Dr. Althea 15% Niacinamide Purity Serum 30ml

Dr. Althea built this serum around a high 15% dose of niacinamide, so the focus is clear from the first drop: smaller-looking pores, a more even tone and a smoother surface. The texture is watery and light, sinks in fast and leaves no tacky film, which is why it sits comfortably under the rest of a Korean routine. Zinc PCA keeps the formula balanced for skin that gets shiny by midday but still wants hydration, and the fragrance-light base is friendly to sensitive skin.

Who is it for?

Combination, oily and sensitive skin that wants visibly refined pores and a brighter, more even-looking tone. If heavier serums feel greasy on you, this lightweight texture is an easy swap.

Key ingredients

• Niacinamide (15%) – A vitamin B3 derivative that helps improve the look of enlarged pores, uneven tone and dullness for a smoother, brighter finish.
• Zinc PCA – A mineral-derived ingredient that helps keep excess shine in check while giving the skin light hydration, so the complexion feels balanced and less congested.
• MELACUT Complex – Dr. Althea's patented blend of four components, included to support a more even, luminous-looking tone and overall clarity.

How do you use it?

Apply after toner and before moisturiser. Smooth a few drops over clean skin morning and evening, then follow with cream. For daytime use, finish your routine with sunscreen.

What does it feel like?

Light, refreshing and non-sticky. It absorbs quickly without residue, so makeup and the rest of your steps layer cleanly on top. With consistent use, skin looks smoother, clearer and more radiant while staying comfortable and hydrated.
