The Lovi Fit is the same in every country; only the stores and prices differ, and the ones here are for Australia.

[Potassium](https://lovi.care/skincare/au/ingredients/potassium) hydroxide does not produce any visible skin effects in these study findings. It suits most skin types best and comes in [serums](https://lovi.care/skincare/au/ingredients/serum). You can fit it into a routine by keeping it apart from [vitamin C](https://lovi.care/skincare/au/ingredients/vitamin-c), [bio-placenta peptides](https://lovi.care/skincare/au/ingredients/bio-placenta-peptides), and [hexapeptide](https://lovi.care/skincare/au/ingredients/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.

Ingredient Together How to use them

[Vitamin C](https://lovi.care/skincare/au/ingredients/vitamin-c) Keep apart Use them at different times of day with [vitamin C](https://lovi.care/skincare/au/ingredients/vitamin-c) first, because mixing them makes the vitamin C spoil and stop working. [Potassium hydroxide and vitamin C](https://lovi.care/skincare/au/ingredients/vitamin-c-and-potassium-hydroxide) [Bio-placenta peptides](https://lovi.care/skincare/au/ingredients/bio-placenta-peptides) Keep apart Use them at different times of day by applying the peptides first and the [potassium](https://lovi.care/skincare/au/ingredients/potassium) hydroxide later, because they cancel each other out. [Potassium hydroxide and bio-placenta peptides](https://lovi.care/skincare/au/ingredients/bio-placenta-peptides-and-potassium-hydroxide) [Hexapeptide](https://lovi.care/skincare/au/ingredients/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](https://lovi.care/skincare/au/ingredients/hexapeptide-and-potassium-hydroxide) [Acetyl hexapeptide-3](https://lovi.care/skincare/au/ingredients/acetyl-hexapeptide-3) Keep apart Use them at different times of day, applying [acetyl hexapeptide-3](https://lovi.care/skincare/au/ingredients/acetyl-hexapeptide-3) first and potassium hydroxide later, because they clash in acidity. [Potassium hydroxide and acetyl hexapeptide-3](https://lovi.care/skincare/au/ingredients/acetyl-hexapeptide-3-and-potassium-hydroxide) [Collagen peptide](https://lovi.care/skincare/au/ingredients/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](https://lovi.care/skincare/au/ingredients/potassium-hydroxide-and-collagen-peptide) [Copper peptide](https://lovi.care/skincare/au/ingredients/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](https://lovi.care/skincare/au/ingredients/potassium-hydroxide-and-copper-peptide) [Hexapeptide-9](https://lovi.care/skincare/au/ingredients/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](https://lovi.care/skincare/au/ingredients/potassium-hydroxide-and-hexapeptide-9) [Peptide-rich plasma](https://lovi.care/skincare/au/ingredients/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](https://lovi.care/skincare/au/ingredients/potassium-hydroxide-and-peptide-rich-plasma) [Triple peptide blend](https://lovi.care/skincare/au/ingredients/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](https://lovi.care/skincare/au/ingredients/potassium-hydroxide-and-triple-peptide-blend) [Palmitoyl pentapeptide-4](https://lovi.care/skincare/au/ingredients/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](https://lovi.care/skincare/au/ingredients/potassium-hydroxide-and-palmitoyl-pentapeptide-4) [Palmitoyl tripeptide-1](https://lovi.care/skincare/au/ingredients/palmitoyl-tripeptide-1) Keep apart Apply the peptide product first and the potassium hydroxide product later, because high alkalinity destroys peptide stability.

## Questions and answers

### What does potassium hydroxide do for the skin?

[Potassium](https://lovi.care/skincare/au/ingredients/potassium) hydroxide is used as a pH adjuster in skincare products to help balance acidity levels.

### How do you use potassium hydroxide?

Potassium hydroxide is used at different times of day from certain partner ingredients like [vitamin C](https://lovi.care/skincare/au/ingredients/vitamin-c) and various peptides to prevent them from spoiling or losing their effectiveness.

### Should you use potassium hydroxide in the morning or at night?

You can use potassium hydroxide in your routine, but you must keep it apart from vitamin C and various peptides by using those partner ingredients at different times of day.

### Can you use potassium hydroxide every day?

Potassium hydroxide may be used every day depending on the specific product instructions, though you should keep it apart from certain active ingredients like vitamin C or peptides by using them at different times of day.

### Does potassium hydroxide cause purging or irritation?

Potassium hydroxide may cause skin irritation because it is a strong alkali that affects skin balance.

### Which skin types is potassium hydroxide best for?

Potassium hydroxide is not categorized by skin type on this page, but it is found in popular products like Glytone Mild Gel Cleanser.

### Can you use potassium hydroxide with vitamin C?

Keep potassium hydroxide and vitamin C apart and use them at different times of day with vitamin C first, because mixing them makes the vitamin C spoil and stop working.
