Things to note after freezing mole removal, these aspects should be done well

There are many ways to remove moles, the most common ones are laser mole removal, freezing mole removal, and surgical removal, but the most important thing is the precautions after mole removal. Keep it dry after mole removal, eat a light diet, do not scratch the place where the mole was removed, and pay attention to sun protection.

1. Precautions after mole removal

1. Keep the treated area as dry as possible for one week after removing moles or spots. Dry it gently with a clean towel as soon as possible after washing or contact with water.

2. After treating moles and spots, the treated area should be kept away from sunlight to prevent sunburn and pigmentation. Especially within 20 days after the scabs fall off, special attention should be paid to sun protection.

3. Pay attention to your diet and try to eat less sour and spicy foods, seafood, beef, mutton and other foods. Eat more foods containing vitamin C. You can also supplement vitamin C and vitamin E and take them according to the instructions.

4. Please do not scratch at will to avoid infection, which may lead to scars or pigmentation.

5. After mole removal treatment, a black scab will generally form on the applied area within 1-2 days, and the scab will fall off automatically in about 1-2 weeks. After the scab falls off, it is best if the skin where the scab falls off is white. If it is fresh red skin, the color will sometimes darken due to excessive sunlight exposure, and it will recover after a few months.

2. Mole removal method

1. Electric burning method

Method: Use the principle of electric high-temperature burning to remove the mole by burning and carbonization.

Advantages: Easy to operate.

Disadvantages: It is difficult to control the degree of burning, it is easy to leave scars, and it is not accepted by people.

Indications: It is effective for shallow combined nevi and deeper and raised compound nevi, and for nevi with a diameter of 0.3-0.5 cm.

2. Surgical resection

Method: Surgical removal of the diseased tissue around the mole.

Advantages: This method can choose to partially or completely remove the diseased tissue, and different treatment methods can be used depending on the nature of the mole.

Disadvantages: It is difficult and time-consuming, so this method is rarely used for common moles.

Indications: Large, raised moles with a diameter greater than 0.6 cm.

3. Chemical corrosion method

Method: Generally, a 50% concentration of trinitrocarbonic acid solution or alkaline agents such as sodium hydroxide are applied to the mole.

Advantages: Tricarbonic acid solution is not easy to burn the skin and cause scars; alkaline solution is highly corrosive and may take effect quickly.

Disadvantages: The effect of trinitrocarbonic acid solution is slow, and deeper moles may need to be treated 10 times; sodium hydroxide is not easy to control the corrosion depth, which may cause deep scars

Indications: Moles with lighter color and shallow location.

4. Freezing method

Method: Use liquid nitrogen to freeze the nevus tissue extremely quickly, causing the cells around the nevus to form blisters and then fall off on their own.

Advantages: The depth of destruction is relatively easy to control, it can usually be done in one go, and it is not easy to cause obvious scars.

Disadvantages: Large and thick moles need to be frozen multiple times to be removed, and special instruments must be used. The doctor's skills are also very important. Since it is difficult to control the depth and often causes damage, dermatology departments do not usually use it to treat moles.

Indications: Flat moles with a diameter of 0.3-0.5 cm, including freckles, etc.
