Should a tranexamic-acid serum be applied to a spot or a wider area?
Marked historical: the newest linked discussion was published more than 24 months before this answer was reviewed.
Use the exact serum’s application directions. The reviewed Haruharu Wonder TXA manual does not settle spot-only versus whole-face use.
Products, directions & sources
- Its recorded instructions place a moderate, unmeasured amount after cleansing and toner, with gentle massage, morning and evening. The application-area field remains undisclosed. Haruharu Wonder source
- The same dated formula lists Tranexamic Acid (4%). A disclosed concentration does not supply a missing application-area instruction. Haruharu Wonder source
