Dermatology is a specialty that includes both medical and surgical parts dealing with skin conditions. A dermatologist is a qualified doctor who treats disorders of the skin, hair, nails, and some aesthetic issues. They also detect symptoms on your skin that may suggest internal issues, such as organ dysfunction or failure. Dermatologists frequently conduct specific diagnostic techniques for skin conditions.
The skin is the body's largest and also most visible organ. It represents the body's health and serves as a barrier against injury and infection. Unfortunately, nearly everyone gets skin conditions at some point in their lives - newborns, adolescents, teens, adults, and the old.

1. Surgical Excision For Mole Removal

Excision is a typical method for removing moles. Your surgeon will use a scalpel to remove your mole from the surface of your skin after cleaning and numbing the location. Depending on the kind of mole, a margin of healthy skin will be excised to verify that all abnormal cells are eliminated. The mole is then peeled away using forceps to grab the portion. Bleeding is typical, and before stitching the region back together, your surgeon may exert pressure on the skin or burn (cauterize) it to stop the bleeding.

2. Cryotherapy For Skin Lesions

Cryotherapy is a treatment for destroying the tissue that involves intense cold (liquid nitrogen). It's frequently used to treat skin lesions, which are abnormal skin growths or areas that don't match the skin around them. Lesions may include:
•    Benign (not malignant) 
•    Actinic Keratosis: These are precancerous skin malignancies that appear as scaly patches on your skin and have the potential to develop into cancer in the future.
•    Superficial skin carcinoma (skin cancer that is visible on the skin's surface).
Cryotherapy also helps in the preservation of the region surrounding the lesions and the reduction of scarring to the extent possible.  You don't need to do anything to prepare for cryotherapy, but you should remove any makeup, moisturizer, or powder before the procedure.

3. Laser Skin Resurfacing

Laser resurfacing uses lasers to decrease the appearance of wrinkles and scars, balance out the color of skin (pigmentation), tighten skin, and eliminate benign (non-cancerous) and malignant tumors. Short, focused pulsating light beams are directed towards uneven skin using the laser method. Laser skin resurfacing eliminates skin layer by layer by vaporizing it. Lasers remove the outermost layer of your skin, known as the epidermis while heating the underlying layer, known as the dermis. The lasers promote the creation of new collagen fibers, resulting in smoother and firmer skin.

4. Laser Hair Removal

Laser hair removal is a medical procedure that uses a focussed beam of light to eliminate unwanted hair. The light energy is converted into heat, which kills the skin's hair-producing tube-shaped sacs (hair follicles). It stops or delays future hair development. Although laser hair removal can effectively delay hair growth for a long period of time, it seldom results in permanent hair reduction. Laser hair removal is most successful on those with fair skin.

5. Mohs Surgery:

Skin cancer is treated by Mohs surgery. Common kinds of skin cancer include basal cell carcinoma and squamous cell carcinoma. Melanoma and other less frequent skin cancers are also treated with it.
Mohs surgery is most effective for skin malignancies that: 
•    Are at high risk of recurrence or have reappeared after earlier therapy.
•    Are in locations where it is important to preserve as much healthy tissue as possible. This includes the eye, ear, nose, mouth, hands, feet, and genital regions.
•    Have difficult-to-define edges.
•    Are large or expand rapidly
Most wounds are treated at the end of the Mohs surgery. If the wound is big or complicated, the surgeon may seal it temporarily. Another procedure to heal the wound may be required, however, this is uncommon.
Wear a bandage over the wound for a week or more. The length of time you'll have a bandage depends on your condition. Your surgeon will instruct you on how to care for the wound. You may need to replace the bandage daily.
