Ingredients Details
Tranexamic Acid
Common Name(s): Trans-4-aminomethylcyclohexanecarboxylic acid,txa,cyklokapron
CAS Number: 1197-18-8
DESCRIPTION
What It Does: Provides brightening by inhibiting uv-induced plasminogen activation that triggers melanocyte stimulation.
Why It's Used: Novel brightening mechanism โ tranexamic acid targets uv-induced melanocyte stimulation upstream of tyrosinase activity, providing complementary brightening to tyrosinase inhibitors with exceptional tolerability.
How It Works: Lysine analogue binds lysine-binding sites on plasminogen preventing its conversion to plasmin. uv-activated plasmin normally increases keratinocyte arachidonic acid release stimulating melanocyte activity via prostaglandin e2 and alpha-msh. txa blocks this uv-melanocyte signalling cascade upstream of pigment synthesis.
Typically Found In: Brightening serums,anti-melasma products,uv-induced pigmentation
TECHNICAL DETAILS
Primary Category: Active ingredient โ lysine analogue brightening

SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. use with spf for maximum efficacy. ewg score: 1.
Works Well With: Niacinamide,vitamin c,alpha-arbutin,tranexamic acid,spf
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Tranexamic acid's brightening mechanism was discovered serendipitously โ it was originally a haemostasis drug for reducing surgical bleeding. dermatologists noted that patients receiving txa for bleeding showed improved melasma, leading to investigation that revealed the plasminogenโprostaglandinโmelanocyte signalling cascade as a completely previously unknown brightening target.

Water
Common Name(s): Water,purified water,deionised water,inci water
CAS Number: 7732-18-5
DESCRIPTION
What It Does: Provides the universal solvent and vehicle for water-soluble actives and the continuous phase of all o/w emulsions.
Why It's Used: The most essential cosmetic ingredient โ aqua (water) is listed first on virtually all water-containing cosmetic inci labels as the highest-concentration ingredient, serving as the foundation of the global cosmetics industry.
How It Works: Acts as solvent for all water-soluble ingredients (glycols, amino acids, water-soluble actives). forms the continuous external phase of o/w emulsions (lotions, creams, serums). provides aqueous environment for enzymatic and chemical reactions between actives. ph adjustment medium.
Typically Found In: Virtually all cosmetic products โ the most universal cosmetic ingredient globally
TECHNICAL DETAILS
Primary Category: Functional ingredient โ water
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care

SOURCING & ETHICS
Vegan Status: Yes โ water (deionised/purified)
Halal Status: Yes
Source Notes: Cosmetic-grade water is purified (deionised, distilled, or ro filtered) to prevent mineral content interference with formulation stability. european pharmacopoeial water (aqua purificata ph. eur.) is the quality standard for pharmaceutical and high-end cosmetic formulations.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ non-irritant
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Well-tolerated by most skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Good safety profile at recommended concentrations. ewg score: 1โ2.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Water's position as the first inci ingredient on most cosmetic labels reflects the regulatory requirement to list ingredients in descending concentration order โ meaning water is the most abundant ingredient in the majority of cosmetic products. the fundamental role of water as the universal cosmetic solvent and vehicle makes it simultaneously the most important cosmetic ingredient and the one that requires the most sophisticated formulation chemistry to control โ every emulsifier, thickener, preservative, and ph adjuster exists primarily to manage water's interaction with other ingredients in formulation.
