COSRX The Blue Peptide Bakuchiol Plump Glow Serum

COSRX The Blue Peptide Bakuchiol Plump Glow Serum is the fluid treatment step of the Blue Peptide range. It runs thin and spreads easily, and the brand builds it around bakuchiol plus the naturally blue Copper Tripeptide-1 for people beginning early-signs-of-aging care.

What it actually does

• Brings back a look of vitality. COSRX attributes this to the blue-toned Copper Tripeptide-1, for a firmer and more energised-looking complexion.
• Works on pores, texture and radiance together. The brand centres the multi-action formula on bakuchiol to visibly reduce the appearance of pores, smooth texture and lift radiance.
• Plumps and hydrates. COSRX describes the result as a bouncy, deeply hydrated-looking complexion with a glass-like glow.
• Sits under everything easily. The lightweight, fluid texture is meant to spread without drag and leave the surface looking even rather than tacky.
• Aimed at early concerns. The brand lists sensitive skin doing daily early-aging care, skin lacking firmness and elasticity, dehydrated or dry skin, enlarged pores and rough texture, and dark spots or uneven tone.

How to use

1. Cleanse, then prep with toner. The serum goes on after both.
2. Take an adequate amount and spread it across the face working from the inside outwards, keeping away from the eye area.
3. Follow with a cream to seal it — the Blue Peptide cream is built to go on top.

Cautions from COSRX: stop and see a dermatologist if irritation, redness, swelling or itching appears during or after use. Do not apply to broken or damaged skin. Store away from direct sunlight and keep out of reach of children.

Questions

Do I need the cream as well?

The serum is a treatment fluid, so you still want a moisturiser after it. The Blue Peptide cream in the same line is designed to sit on top and seal in what the serum leaves behind.

Morning or night?

COSRX positions it as daily care, applied after cleansing and toner. The fluid texture means it layers fine under sunscreen and makeup in the morning.

Why is it blue?

Copper Tripeptide-1 carries a natural blue tint — that is where the colour and the range name come from.
