Dermatologists use chemical peels to treat:
Acne-red inflammatory and noninflammatory (comedonal) lesions.
Age spots/seborrheic keratosis.
Discoloration (blotchy complexion, uneven skin tone, pigmentation).
Dull complexion.
Fine lines on face (especially under the eyes and around the mouth).
Freckles/Lentigines.
Melasma.
Rough-textured skin.
Sun-damaged skin.
Chemical peel diminishes signs of aging by causing:
Fewer fine lines and wrinkles.
More even skin tone.
Brighter complexion.
Smoother skin.
Microneedling (Skin Needling, Dermaroller)
Microneedling (Skin Needling, Dermaroller)
Microneedling involves puncturing the skin with thin needles to create tiny wounds, triggering the skin’s healing mechanisms and stimulating collagen production. Depending on the depth of penetration of the needles, this treatment can be used to treat acne scars, stretch marks, improving fine lines and the texture of the skin.

Roller microneedling devices used at home or at nonmedical spas have shorter, dull needles and are not meant to penetrate the skin. They may create a temporary brightening effect by stimulating blood flow. However, they don’t deliver equivalent results as a microneedling treatment from a doctor. At-home microneedling devices are difficult to clean and maintain, with needles that dull quickly leading to injury or infection, rather than rejuvenation.

Microneedling does not involve the delivery of heat, so patients of all skin types can receive the treatment without the risk of pigmentation issues that accompanies laser and light procedures, involving heat.
