innisfree Green Tea Enzyme Vitamin C Brightening Serum: Vitamin C With Green Tea Antioxidant Pairing

innisfree's Green Tea Enzyme Vitamin C Brightening Serum combines two of the brand's strongest ingredients: Jeju green tea (the brand's signature) and vitamin C for brightening. The formula uses a stabilized form of vitamin C paired with green tea extract's catechins, which create a synergistic antioxidant effect (green tea helps stabilize and boost vitamin C performance).

This is innisfree's step up into active-treatment territory. Most innisfree products focus on hydration and maintenance; this serum targets actual pigmentation and dullness. At $62 for 50ml, it's mid-range for vitamin C serums: not as cheap as COSRX, not as clinical as SKINCEUTICALS, but a solid middle-ground pick.

What It Does

Stabilized vitamin C (typically an ascorbic acid derivative or ethyl ascorbic acid) brightens pigmentation and supports collagen production. Green tea catechins (EGCG specifically) provide potent antioxidant protection and stabilize the vitamin C. The combination is synergistic: green tea protects vitamin C from oxidation, and vitamin C amplifies the catechin brightening effect. Over 6 to 10 weeks, pigmentation fades and skin looks brighter.

Who It's For

• Pigmentation and dullness: Primary target concerns.
• Vitamin C first-timers: Gentler than pure ascorbic acid.
• innisfree routine users: Fits the green tea line.
• Sensitive-to-L-ascorbic-acid users: Stabilized form is milder.
• Daily maintenance users: Safe long-term.

FAQ

How does it compare to pure L-ascorbic acid serums?

L-ascorbic acid is more potent but more irritating and less stable. Stabilized forms like this product are gentler, easier to layer, and still effective over longer timelines.

Will it cause purging?

Rarely. Vitamin C doesn't typically cause purging the way retinoids can.

Can I layer with retinol?

Yes, but easier to alternate: vitamin C AM, retinol PM. Layering both PM can over-tax sensitive skin.

Safe during pregnancy?

Generally yes. Vitamin C is considered pregnancy-friendly. Consult your OB.

How long until I see brightening results?

Glow: 2 to 4 weeks. Pigmentation fading: 6 to 10 weeks.
