Potassium hydroxide

Potassium hydroxide does not produce any visible skin effects in these study findings. It suits most skin types best and comes in serums. You can fit it into a routine by keeping it apart from vitamin C, bio-placenta peptides, and hexapeptide.

This page shows potassium hydroxide products with a Lovi page. For every product, and a routine built for your skin, use the Lovi app.

What to combine potassium hydroxide with

IngredientTogetherHow to use them
Vitamin C Keep apart Use them at different times of day with vitamin C first, because mixing them makes the vitamin C spoil and stop working. Potassium hydroxide and vitamin C
Bio-placenta peptides Keep apart Use them at different times of day by applying the peptides first and the potassium hydroxide later, because they cancel each other out. Potassium hydroxide and bio-placenta peptides
Hexapeptide Keep apart Use them at different times of day, applying the peptide first and the potassium hydroxide later, because they clash in chemical balance. Potassium hydroxide and hexapeptide
Acetyl hexapeptide-3 Keep apart Use them at different times of day, applying acetyl hexapeptide-3 first and potassium hydroxide later, because they clash in acidity. Potassium hydroxide and acetyl hexapeptide-3
Collagen peptide Keep apart Use them at different times of day, applying the peptide first and the potassium hydroxide later, because they clash in chemical balance. Potassium hydroxide and collagen peptide
Copper peptide Keep apart Use them at different times of day, applying the peptide first, because high alkalinity ruins the peptide. Potassium hydroxide and copper peptide
Hexapeptide-9 Keep apart Use them at different times of day with the peptide first, because high alkalinity ruins the peptide. Potassium hydroxide and hexapeptide-9
Peptide-rich plasma Keep apart Use them at different times of day, applying the peptide product first and the potassium hydroxide later, because they clash and ruin results. Potassium hydroxide and peptide-rich plasma
Triple peptide blend Keep apart Use them at different times of day with the peptide product first, because high alkalinity destroys the peptides. Potassium hydroxide and triple peptide blend
Palmitoyl pentapeptide-4 Keep apart Use them at different times of day, applying the peptide first and the potassium hydroxide later, because they clash and cancel each other out. Potassium hydroxide and palmitoyl pentapeptide-4
Palmitoyl tripeptide-1 Keep apart Apply the peptide product first and the potassium hydroxide product later, because high alkalinity destroys peptide stability. Potassium hydroxide and palmitoyl tripeptide-1
