The INKEY List Tranexamic Acid Serum 1 fl oz — 2% Tranexamic Acid, Vitamin C Brightening

This lightweight serum is designed to be used as part of an evening routine to target hyperpigmentation, uneven patches and post-inflammatory discoloration. The formula combines tranexamic acid — known in skincare for pigment-targeting — with antioxidant-rich acai and vitamin C to support visible skin brightness without heavy textures. Packed into a 1 fl oz bottle, it layers easily under moisturizers and is intended for nightly application until desired results are achieved.

How quickly will I notice changes to dark spots and uneven tone?

Individual results vary, but most users notice subtle brightening within a few weeks and more pronounced changes over 6–12 weeks with consistent nightly use. Because pigment changes take time to fade, regular application and sun protection during the day help preserve progress.

• Apply nightly for best cumulative effect
• Expect gradual improvement rather than immediate disappearance
• Pair with daily SPF to protect results

How do the active ingredients work together in this serum?

Tranexamic acid targets pigment irregularities, while 2% acai berry extract brings antioxidant support and 2% vitamin C helps brighten overall skin appearance. Together they create a multi-pronged approach: reducing the look of dark spots, boosting surface radiance and helping skin appear more even without a heavy formula.

• 2% tranexamic acid for pigment-targeting action
• 2% acai berry extract for antioxidant support
• 2% vitamin C to lift overall brightness

Can I layer this serum with other products safely?

The lightweight, water-based texture is designed for easy layering under moisturizers and most treatment products. To avoid irritation, introduce it gradually if you use strong actives like retinoids or exfoliating acids, and always finish daytime routines with SPF.

• Use after cleansing and before heavier creams
• Introduce gradually alongside retinoids or acids
• Finish daytime use with broad-spectrum SPF

Is this suitable for sensitive or acne-prone skin?

The formula is generally lightweight and non-greasy, but sensitivity varies; perform a patch test if you have reactive skin. If irritation occurs, reduce frequency or consult a skincare professional for personalized guidance.

• Patch test before full-face use
• Reduce frequency if irritation appears
• Safe to pair with many non-irritating hydrators

Who is this for: This serum is intended for people seeking to reduce the visible appearance of dark spots, hyperpigmentation and uneven skin tone who want a lightweight, evening treatment. It suits those who prefer targeted actives over heavy creams and are committed to consistent nightly use plus daytime sun protection to maintain results.
