## Abstract

A system and method for laser skin resurfacing is provided. The system comprises a topical numbing composition, cryogenically cooled air, a fractional laser, and one or more topical compositions. The topical numbing composition and the cryogenically cooled air are operative to reduce patient pain and discomfort. The cryogenically cooled air is further operative to protect the patient's skin from thermal damage. The fractional laser is operative to ablate the patient's skin cells. The method comprises the steps of applying a topical numbing composition to an area of a patient's skin comprising the treatment area; directing cryogenically cooled air and a fractional laser to the treatment area; and applying one or more topical compositions to the treatment area. The system and method stimulates collagen production in the patient's skin, diminishes inflammation and damage to the patient's skin, reduces patient recovery time following a laser resurfacing procedure, and ultimately, maximizes patient satisfaction with the procedure.

## Claims

### Claim 1

A system for laser skin resurfacing, comprising:
a topical numbing composition operative to reduce a patient's discomfort comprising lidocaine and epinephrine;
air cryogenically cooled to about −6° C. operative to protect the patient's skin from thermal damage and reduce pain and inflammation;
a fractional laser, operative to ablate one or more cells of the patient's skin; and
one or more topical compositions comprising kojic acid, hydroquinone, hydrocortisone, clindamycin, and retinoic acid.

### Claim 2 (depends on 1)

The system of claim 1, wherein the topical numbing composition is a combination of lidocaine and epinephrine.

### Claim 3 (depends on 1)

The system of claim 1, wherein the fractional laser is a carbon dioxide laser.

### Claim 4 (depends on 1)

The system of claim 1, further comprising
up to 0.5% wt. lidocaine; and
up to 0.01% wt. epinephrine.

### Claim 5 (depends on 1)

The system of claim 1, further comprising
up to 4.0% wt. kojic acid; and
up to 0.1% wt. retinoic acid.

### Claim 6 (depends on 1)

The system of claim 1, wherein one of the one or more topical compositions comprises hydroquinone, hydrocortisone, and clindamycin; and another one of the one or more topical compositions comprises retinoic acid and kojic acid.

### Claim 7 (depends on 6)

The system of claim 6, wherein the one or more topical compositions comprise
up to 8.0% wt. hydroquinone;
up to 0.1% wt. retinoic acid;
up to 0.4% wt. hydrocortisone;
up to 1.0% wt. clindamycin; and
up to 3.0% wt. kojic acid.

### Claim 8 (depends on 6)

The system of claim 6, wherein the one or more topical compositions stimulate collagen production in the patient's skin.

### Claim 9

A method for laser skin resurfacing, comprising:
applying a topical numbing composition comprising betamethasone, lidocaine, and epinephrine to an area of a patient's skin comprising the treatment area, wherein the treatment area comprises one or more skin conditions;
directing air cryogenically cooled to about −6° C., and a fractional laser to the treatment area; and
after directing the laser to the treatment area, applying one or more topical compositions comprising at least kojic acid and retinoic acid to the treatment area.

### Claim 10 (depends on 9)

The method of claim 9, wherein the one or more skin conditions are wrinkles, melasma, acne, stretchmarks, discoloration, or scarring.

### Claim 11 (depends on 9)

The method of claim 9, wherein the fractional laser, the cryogenically cooled air, and the one or more topical compositions treat the one or more skin conditions.

### Claim 12 (depends on 9)

The method of claim 9, wherein the one or more topical compositions are formulated to reduce pain and inflammation.

### Claim 13 (depends on 9)

The method of claim 9, wherein the one or more topical compositions are formulated to stimulate collagen production.
