## Abstract

A broad spectrum sun protection transfer device includes a backing paper; a release coating affixed to the backing paper; and a sun protection transfer film deposited on the release coating. The transfer film is adhesive to skin and opaque to ultraviolet radiation. The transfer film significantly reduces UV radiation penetrating high risk areas of the skin for a long duration of protection.

## Claims

### Claim 1

A broad spectrum sun protection transfer device, comprising:
a) a backing paper;
b) a silicone release coating affixed to the backing paper; and
c) an overlay sun protection deposited on the silicone release coating, wherein the overlay sun protection is characterized by adhesiveness to skin and substantial opacity to ultraviolet radiation;
wherein the overlay sun protection is applied by placing the overlay sun protection with transfer film side down, placed against the skin; applying water to the backing paper wetting thoroughly with a sponge or cloth; wait 20-30 seconds; and peeling away the backing paper with the silicone release coating affixed thereto, leaving the overly sun protection adhered to the skin.

### Claim 2 (depends on 1)

The broad spectrum sun protection transfer device of claim 1, further comprising a protective sheet releasably attached to the sun protection transfer film.

### Claim 3 (depends on 1)

The broad spectrum sun protection transfer device of claim 1, wherein the overlay sun protection is configured to cover a high risk area selected from the group consisting of: malar; posterior neck; clavicular; an ear helix; a dorsal surface of a hand; and a combination thereof.

### Claim 4 (depends on 1)

The broad spectrum sun protection transfer device of claim 1, wherein the broad spectrum sun protection transfer device is a layered sheet having regions configured to have shapes corresponding to a template of high risk areas selected from the group consisting of: malar; posterior neck; clavicular; a helix of an ear; a dorsal surface of a hand; and a combination thereof.

### Claim 5 (depends on 1)

The broad spectrum sun protection transfer device of claim 1, characterized in that the sun protection transfer film is operative to reflect UV radiation.

### Claim 6 (depends on 5)

The broad spectrum sun protection transfer device of claim 5, wherein the overlay sun protection is transparent to radiation in a visible light spectrum.

### Claim 7 (depends on 1)

The broad spectrum sun protection transfer device of claim 1, characterized in that the overlay sun protection is operative to physically block UV radiation.

### Claim 8 (depends on 7)

The broad spectrum sun protection transfer device of claim 7, wherein the overlay sun protection comprises a UV radiation blocking ingredient selected from the group consisting of zinc oxide; a hypoallergenic, skin-safe pigment; a hypoallergenic, skin-safe ink; and combinations thereof.

### Claim 9 (depends on 1)

The broad spectrum sun protection transfer device of claim 1, wherein the overlay sun protection comprises a carrier vehicle.

### Claim 10 (depends on 9)

The broad spectrum sun protection transfer device of claim 9, wherein the carrier vehicle is selected from the group consisting of: gelatin; polyvinyl alcohol; polyvinyl pyrrolidone; and combinations thereof.

### Claim 11 (depends on 1)

The broad spectrum sun protection transfer device of claim 1, wherein the silicone release coating is a second layer fastened between a first layer comprising the backing paper and a third layer comprising the overlay sun protection, and wherein a surface of the third layer opposite the second layer is configured to be placed on the skin.
