Standing in front of a shelf of serums is confusing — they all promise glowing skin. The trick is to match the serum to your main concern. Here's a plain guide using what we carry at Filsora.

"I break out / my skin is oily"

Look for gentle exfoliation and calming repair. Start with COSRX Salicylic Acid Cleanser to keep pores clear, add Some By Mi 30 Days Miracle Serum for acne-prone skin, and keep COSRX Acne Pimple Master Patches on hand for individual spots. COSRX Advanced Snail 92 Cream helps heal marks left behind.

"I have dark spots or uneven tone"

This is a brightening job. Axis-Y Dark Spot Correcting Serum, COSRX Vitamin C23, Beauty of Joseon Glow Serum and Eqqualberry Vitamin Illuminating Serum all target dullness and pigmentation. Pair any of them with daily sunscreen — otherwise the sun undoes the work.

"I'm seeing fine lines / want firmer skin"

Retinol is the gold standard. Some By Mi Retinol Intense Reactivating Serum, used a few nights a week at first, softens fine lines and smooths texture over time. Always follow with sunscreen the next morning.

"My skin feels tight and dry"

You need water and a seal. Layer Haruharu Black Rice Toner, then Isntree Hyaluronic Acid Moist Cream or COSRX Hyaluronic Acid Intensive Cream to lock it in.

"My skin is sensitive or red"

Go calming and barrier-first. Benton Aloe Propolis Soothing Gel, Some By Mi Beta Panthenol Repair Cream and Anua Heartleaf soothe redness and strengthen your skin barrier.

"I want to balance oil without drying out"

COSRX The Niacinamide 15 and The Ordinary Niacinamide 10% + Zinc help regulate oil and refine pores gently.
