Combining BHA and Tranexamic Acid in a Serum

Yes, Salicylic Acid (BHA) and Tranexamic Acid can be combined in a serum formulation. Tranexamic Acid is stable enough to be used in formulations with the lower pH required for BHA to be effective.

• Salicylic Acid (BHA) is highly effective for treating acne, particularly clogged pores, as it can penetrate oil and exfoliate inside the pore. It also has mild exfoliating properties on the skin surface.
• Tranexamic Acid is known for its ability to brighten skin and is effective in reducing the appearance of melasma and hyperpigmentation by inhibiting melanin production.

Combining these two ingredients can create a serum that targets both acne and hyperpigmentation concerns. You may see results in addressing both issues with this combination.

However, for addressing melasma and overall skin exfoliation more broadly, Alpha Hydroxy Acids (AHAs) like Glycolic Acid are often considered more effective than BHA. Glycolic Acid helps to accelerate skin cell turnover, which can improve skin texture, tone, and the appearance of dark spots.

Therefore, depending on whether your primary concern is clogged pores/acne or melasma/hyperpigmentation, you might also consider a combination of:

• Tranexamic Acid + Glycolic Acid (AHA): This combination is often recommended for targeting melasma and providing general exfoliation benefits.

Ultimately, the choice of ingredients depends on the specific skin concerns you wish to address and the desired focus of the serum.
