Can You Use PHA Acids (Gluconolactone) and Tranexamic Acid Together? Compatibility & Layering

Compatible & Safe to Layer — «PHA Acids (Gluconolactone, Lactobionic Acid)» and «Tranexamic Acid (TXA)» have no known negative chemical interactions and can be safely layered together.

Active A🌙 Evening (PM)

PHA Acids (Gluconolactone, Lactobionic Acid)

Large-molecule gentle exfoliating polyhydroxy acids. Provides mild resurfacing while locking in moisture.

Optimal pH:3.8 - 4.5
Layering Step:Step 2: Water-Based Active Serum
✓ Safe for reactive/rosacea-prone skin✓ Humectant resurfacing✓ Antioxidant shielding
Active B☀️/🌙 AM & PM

Tranexamic Acid (TXA)

Non-exfoliating peptide-like active that disrupts melanin synthesis and soothes post-inflammatory redness.

Optimal pH:5.0 - 7.0
Layering Step:Step 2: Water-Based Active Serum
✓ Blocks UV-induced pigment pathway✓ Fades melasma & sun spots✓ Reduces persistent post-inflammatory erythema

💡Dermatologist Protocol (How to Combine):

Layer by texture consistency: apply thin, water-based serums first, followed by heavier creams and oils.

⏱️Which Goes First? (Layering Sequence):

PHA Acids (Gluconolactone) and Tranexamic Acid pair seamlessly in the same routine. Following the dermatological thinnest-to-thickest rule: apply "PHA Acids (Gluconolactone)" as Step 1, allow 1–2 minutes to absorb, and follow with "Tranexamic Acid" as Step 2.

⚗️pH Acidity Spectrum: PHA Acids (Gluconolactone) vs. Tranexamic Acid

Healthy skin barrier maintains a natural acid mantle between pH 4.7 and 5.5. Large pH discrepancies between layered products can destabilize actives or trigger stinging.

pH 2.0 (Acidic)pH 4.7–5.5 (Skin Barrier)pH 7.0+ (Neutral)
PHA Acids (Gluconolactone)pH 3.8 - 4.5
Tranexamic AcidpH 5.0 - 7.0

What is the optimal pH level of PHA Acids (Gluconolactone) vs. Tranexamic Acid?

PHA Acids (Gluconolactone) operates optimally at a pH of 3.8 - 4.5, whereas Tranexamic Acid functions at a pH of 5.0 - 7.0. When combining formulas with different pH windows, always apply the lower-pH watery serum first or split them between your morning and evening routines.

Is layering PHA Acids (Gluconolactone) with Tranexamic Acid safe for sensitive skin?

Yes, pairing PHA Acids (Gluconolactone) with Tranexamic Acid is well-tolerated by sensitive skin types and supports healthy barrier function when sealed with moisturizer.
