The INKEY List Tranexamic Acid Serum 1 oz - 2% Tranexamic Acid Night Serum for Dark Spots & Uneven Tone

The INKEY List Tranexamic Acid Serum is an overnight brightening serum formulated to help diminish the look of dark spots, uneven patches and boost overall skin radiance.

This lightweight night serum combines 2% tranexamic acid with a trio of complementary brightening actives to target visible discoloration and create a more even-looking complexion over time. Designed for evening application, the formula layers easily under moisturizers and focuses on improving the appearance of hyperpigmentation without heavy textures. It is fragrance-free and formulated to integrate into most evening routines alongside exfoliants or retinoids when used thoughtfully.

How does this serum address dark spots and discoloration?

The core active, tranexamic acid at 2%, works alongside vitamin C and acai berry extract to reduce the visual prominence of dark patches. Regular nightly use helps even out tone by targeting areas prone to hyperpigmentation and supporting a brighter-looking surface.

• 2% tranexamic acid targets uneven pigment appearance.
• 2% vitamin C boosts surface brightness for a refreshed look.
• 2% acai berry extract supports a more uniform complexion.
• Lightweight, non-greasy texture for layering under creams.

When should I apply it and how do I layer it with other products?

Use this serum in the evening as the concentrated actives work while skin is in recovery mode. Apply after cleansing and before heavier creams; if you use retinoids or strong exfoliants, introduce the serum gradually to assess tolerance.

• Apply nightly after cleansing and toning, before moisturizer.
• Start every other night if combining with retinoids or acids.
• Always follow with SPF during the day to protect treated areas.

What results can I expect and how long until I see changes?

Most users notice gradual improvements in skin clarity and uniformity rather than immediate transformations. Visible reduction in the prominence of dark spots typically appears after consistent use over several weeks, with optimal results seen when paired with regular sun protection.

• Gradual brightening across multiple weeks of nightly use.
• Reduction of uneven patches with sustained application.
• Enhanced overall radiance when combined with sunscreen daytime.

Is this serum suitable for sensitive or acne-prone skin?

The formula is lightweight and free from added fragrance, which helps keep irritation risk lower for many users. However, because it contains active brightening agents, patch testing and gradual introduction are recommended if you have reactive or very sensitive skin.

• Fragrance-free base reduces common irritation triggers.
• Patch test on inner forearm before full-face use.
• Introduce slowly alongside other actives to gauge compatibility.

Who is this for: This serum is intended for people aiming to visibly even skin tone and lessen the appearance of dark spots and uneven patches without a heavy finish. It works well for those adding a focused brightening step to their evening routine—especially users comfortable with active ingredients and committed to daily SPF to maintain results.
