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

Keep them apart

Use [lactic acid](https://lovi.care/skincare/es/ingredients/lactic-acid) in the morning and [benzoyl peroxide](https://lovi.care/skincare/es/ingredients/benzoyl-peroxide) at night to prevent severe skin irritation and barrier damage. Combining these two active ingredients causes extreme dryness, redness, and peeling because they both work very intensely. You can prevent this by using a lower strength formula or spacing them out by several hours.

## Questions and answers

### Can you use benzoyl peroxide and lactic acid together?

No, you should keep [benzoyl peroxide](https://lovi.care/skincare/es/ingredients/benzoyl-peroxide) and [lactic acid](https://lovi.care/skincare/es/ingredients/lactic-acid) apart to avoid over-exfoliation and irritation. Instead, alternate their use on different days or in separate routines.

### Which goes first, benzoyl peroxide or lactic acid?

You should keep benzoyl peroxide and lactic acid apart by alternating their use on different days or routines because combining them may increase irritation, redness, and barrier damage.

### Are benzoyl peroxide and lactic acid good for sensitive skin?

No, benzoyl peroxide and lactic acid should be kept apart in your routine because combining them may increase irritation, redness, and barrier damage, especially on sensitive skin. You can alternate using them on different days.
