Abstract

Methods for diminishing or reducing pore and hair follicle size in a subject and decreasing or inhibiting undesired activities of enlarged pores such as oily skin, acne and rosacea are provided wherein the skin of a subject is irradiated, preferably via a laser, with electromagnetic radiation at a wavelength sufficient to irradiate vessels surrounding cutaneous sebaceous glands located in the middermis so that an inflammatory response against cutaneous sebaceous glands and surrounding stroma is stimulated.

Claims

1. A method for diminishing or reducing pore and or hair follicle size in a subject comprising irradiating skin of a subject with electromagnetic radiation at a wavelength sufficient to irradiate vessels surrounding cutaneous sebaceous glands located in the mid-dermis so that an inflammatory response against cutaneous sebaceous glands and surrounding stroma is stimulated and pore and hair follicle size is reduced or diminished.

2. The method of claim 1 wherein the skin is irradiated with a pulsed, scanned, or continuous laser light in a wavelength range of 580 to 700 nanometers.

3. The method of claim 1 wherein the enlarged pores are secondary to cutaneous photodamage.

4. The method of claim 1 further comprising topical administration of an alpha-hydroxy acid, a retinoid, or an antioxidant, microdermabrasion or administration of a chemical peel that reduces pore and hair follicle size.

5. A method for reducing or inhibiting undesired activities of enlarged pores or hair follicles in a subject comprising irradiating skin of a subject with electromagnetic radiation at a wavelength sufficient to irradiate vessels surrounding cutaneous sebaceous glands located in the mid-dermis so that an inflammatory response against cutaneous sebaceous glands and surrounding stroma is stimulated and undesired activities of enlarged pores and hair follicle size is reduced.

6. The method of claim 5 wherein the undesired activities cause oily skin, acne or rosacea.

7. The method of claim 5 wherein the skin is irradiated with a pulsed, scanned, or continuous laser light in a wavelength range of 580 to 700 nanometers.

8. The method of claim 5 further comprising topical administration of an alpha-hydroxy acid, a retinoid, or an antioxidant, microdermabrasion or administration of a chemical peel that reduces pore and hair follicle size.
