Hexapeptide and potassium hydroxide
Keep them apart
Use them at different times of day, applying the peptide first and the potassium hydroxide later, because they clash in chemical balance. The potassium hydroxide makes the product too basic, which destroys the anti-aging benefits of the peptide and stops it from working. The shopper can separate them into morning and night routines or choose a gentler formula.

Which goes first, hexapeptide or potassium hydroxide?
Keep hexapeptide and potassium hydroxide apart because highly alkaline environments degrade peptides. Use them in separate routines to maintain peptide stability and effectiveness.
Are hexapeptide and potassium hydroxide good for sensitive skin?
Keep hexapeptide and potassium hydroxide apart because alkaline environments cause peptides to lose stability and activity. Lovi gives them an incompatible fit for sensitive skin.
