Leave the potato juice on the skin for approximately 5 to 10 minutes, then rinse with lukewarm water. Pat your face dry with a clean towel and apply a gentle, fragrance-free moisturizer.
If you have sensitive skin, test the potato on a small area first. Stop immediately if you experience burning, itching, swelling, or significant redness.
For genuine blackhead treatment, the ingredients with better evidence are usually salicylic acid and other products designed to keep pores clear. Salicylic acid is a type of beta-hydroxy acid that can penetrate oily pores and help loosen dead skin cells and excess sebum. A gentle cleanser containing salicylic acid may therefore be more useful for persistent blackheads than relying on a kitchen ingredient alone.
It is also important to remember that blackheads are not simply dirt trapped inside the skin. They form when a pore becomes clogged with oil and dead skin cells, and the material darkens when exposed to air. This is why repeatedly squeezing or scraping them can cause irritation, inflammation, and sometimes lasting marks.
