There's no specific time frame for applying potato juice to your face. You can leave it on for as long as you like, depending on your preference and the desired effect.
Here are some factors to consider:
- Sensitivity: If you have sensitive skin, you might want to start with a shorter application time, like 10-15 minutes.
- Desired effect: If you're looking for a quick pick-me-up, a shorter application may suffice. For more noticeable results, you might leave it on longer, even overnight.
Remember: Always patch test before applying potato juice to your entire face.
