No, it is not safe to use potato juice on your face if it has turned black.
Here's why:
According to the provided reference, potato is a versatile food that can be used in various ways. However, if potato juice turns black, it indicates that it has likely oxidized or started to spoil. Using such juice on your face may cause irritation or adverse reactions.
Understanding the Change in Potato Juice Color
When potato juice turns black, this is typically due to oxidation. This process occurs when the enzymes in the potato react with oxygen in the air. The process can accelerate if the potato is exposed to light and heat. This oxidation process not only changes the color but may also alter the chemical composition of the juice.
Why You Should Avoid Using Blackened Potato Juice on Your Face
- Potential Skin Irritation: The altered chemical components might irritate the skin, leading to redness, itching, or even a rash.
- Bacterial Growth: Blackening can indicate bacterial growth in the juice, which can lead to skin infections if applied to the face.
- Reduced Effectiveness: The beneficial properties of potato juice may be diminished or lost once the juice has oxidized and turned black.
Safe Alternatives
Instead of using blackened potato juice, you can opt for fresh potato juice. If you are using potato for skin treatment, make sure to:
- Use a fresh potato and extract the juice immediately.
- Use the juice within a few minutes of extraction.
- Discard any juice that shows signs of discoloration.

| Safety for Skin | Generally safe if freshly prepared | Not safe, may cause irritation |
| Potential Benefits | Retains beneficial compounds | Loss of beneficial compounds |

In conclusion, while potato juice can be beneficial for skin care, it is essential to use fresh juice and discard it once it starts to darken to avoid any potential skin reactions.
