Tranexamic acid serum — private label & wholesale

What is a cosmetics tranexamic acid serum?

A tranexamic acid serum is a lightweight facial serum that features tranexamic acid — a synthetic amino-acid derivative used in skin care as a skin-conditioning ingredient. Buyers also search for it as a TXA serum or a tranexamic acid face serum. Brands position these serums for a more even-looking tone and a brighter-looking, radiant-looking complexion as part of a daily routine.

Tranexamic acid has become one of the fastest-growing serum stories in K-beauty and clean-clinical retail because it is water-soluble, easy to formulate in light textures, and pairs comfortably with other popular actives. That makes it a strong candidate for a second or third serum in a private-label range.

Formulation notes & pairings

Tranexamic acid level is a formulation choice set in the brief and confirmed on the spec sheet; low single-digit percentages are common in cosmetic serums, and the final figure depends on your base, texture, and market rules. Typical pairings:

• Niacinamide — the most common partner; supports an even-looking, refined-looking finish.
• Vitamin C derivatives — sodium ascorbyl phosphate, ascorbyl glucoside, or 3-O-ethyl ascorbic acid for a radiant-looking story. See our vitamin C serum page for derivative options.
• PDRN — for a hydrating, plumper-looking angle; see the PDRN serum.
• Centella asiatica — for a calming-feel positioning; see the centella asiatica serum.
• Supporting ingredients — hyaluronic acid, panthenol, glycerin, licorice root extract, and alpha-arbutin as an optional brightening-look ingredient where your market allows.

Tranexamic acid is stable across a moderate pH range, which makes it easier to combine than pure L-ascorbic acid; we flag any compatibility points at the brief stage.

Compliance: cosmetics claims by market

Claims for a tranexamic acid serum must stay within the cosmetics regulations of each destination — US cosmetics labeling, EU Cosmetics Regulation (CPNP notification and Responsible Person), UK, and ASEAN notifications. On our program, labels describe appearance only: more even-looking tone, brighter-looking, radiant-looking skin.

Some markets regulate brightening-type claims under separate categories — for example Japan (quasi-drug approvals) and Korea (functional cosmetics registration) — and those routes have their own ingredient, claim, and filing requirements. Brands planning to sell in those markets, or to make category-specific claims anywhere, should confirm positioning with their regulatory adviser before artwork is finalized. We supply INCI, specs, and supporting documents for that review.

Wholesale & range building

Salon groups, retailers, and distributors reorder production programs on wholesale open-account terms with carton-based MOQ tiers. A TXA serum slots neatly into a Clearion Labs range: cleanse with the salicylic acid cleanser, refresh with the hypochlorous acid spray facial mist, tone with rice toner, apply the tranexamic acid serum (or alternate it with a vitamin C serum), then finish with a ceramide moisturizer.
