What is a one-sentence summary of the following article?
Squirt a quarter-sized amount of the mask into a small bowl. Dip a clean brush into the mixture and spread it evenly across your skin. You can apply it over your face or just on blemish-prone areas. Consider spreading it on your t-zone (between your nose and forehead) if you have acne or blackheads.  You can use a wide, flat foundation brush or one made specifically for applying masks. If you don't have a brush, you can use clean fingertips to apply the mask. Try to be as gentle as you can when you spread the charcoal mask on blemish-prone areas to avoid irritation. Because the skin around your eyes and lips is delicate, don't apply the charcoal mask to them. Apply the mask while you're standing in front of a mirror. This way you can see exactly where you're spreading the mask. The mask should dry completely and it will probably feel tight or itchy on your skin. If the mask begins to feel uncomfortable or painful, you should wash it off without waiting for the full 10 minutes to pass. Start at the bottom of the mask and slowly peel upwards towards the top of your face. If you only applied the mask to your t-zone, you can peel near the sides of your nose and pull up towards your forehead. You might notice small bits of the black charcoal mask left on your face. Wash your skin with a gentle cleanser and rinse it off with cool water. Apply a gentle moisturizer that won't clog your pores and let your skin air dry. To limit skin irritation, consider using the charcoal mask just when you have zits or blemishes. Because the charcoal mask will remove the topmost layer of skin and hair from your face, you should wait at least 2 weeks before doing another charcoal mask. If you have eczema or sensitive skin, avoid using charcoal masks, which could damage your skin.

Summary:
Spread the charcoal mask on your face. Avoid spreading the mask near your eyes and lips. Wait for 7 to 10 minutes. Peel off the charcoal mask. Wash and moisturize after you use the mask. Use a charcoal mask every 2 weeks or less.
