Abstract

A device for scar management includes an applicator head including a recess having a rotating means therein, a reservoir containing a silicone composition fluidly connected to the applicator head, and a metering valve fluidly connected to the reservoir. The composition has viscosity of 3,000 to 8,000 cps, and consists of a mixture of cyclopentasiloxane, dimethiconol, dimethicone, and dimethicone/vinyl dimethicone crosspolymer. A metered dose of the silicone composition is delivered from the reservoir to the applicator head upon the application of external pressure to the metering valve. The invention also relates to a method for scar management using such device by identifying a target skin area having a wound or scar, contacting the outward surface of the applicator head to the target skin area, massaging the rotating means of the applicator head on the target skin area, and applying the silicone composition to the target skin area via the rotating means.

Claims

1. A device for scar management comprising:

an applicator head including three recesses each having a rotating ball therein;

a reservoir having a contents consisting of a silicone composition fluidly connected to the applicator head, said composition having a viscosity of 3,000 to 8,000 cps, and consisting of a mixture of cyclopentasiloxane, dimethiconol, dimethicone, and dimethicone/vinyl dimethicone crosspolymer; and

a metering valve fluidly connected to the reservoir, wherein a metered dose of the silicone composition having a volume of 0.03 to 1.0 mL is delivered from the reservoir to the applicator head upon the application of external pressure to the metering valve.

2. The device of claim 1, wherein the ball is spherical.

3. The device of claim 1, wherein the silicone composition further consists of a sun protection agent.

4. The device of claim 1, wherein the metered dose of the silicone composition has a volume of 0.05 mL.

5. A method for scar management comprising:

providing a device having an applicator head including three recesses having three rotating balls therein, a reservoir having a contents consisting of a silicone composition fluidly connected to the applicator head, said composition having a viscosity of 3,000 to 8,000 cps;

identifying a target skin area having a wound or scar;

contacting the outward surface of the device applicator head to the target skin area;

dispensing a fixed amount of the silicone composition having a volume in the range of 0.03 to 1.0 mL from the reservoir to the applicator head;

massaging the rotating ball of the applicator head on the target skin area; and

applying the fixed amount of silicone composition to the target skin area via the rotating ball;

wherein the silicone composition consists of a mixture of cyclopentasiloxane, dimethiconol, dimethicone, and dimethicone/vinyl dimethicone crosspolymer.

6. The method of claim 5, wherein the massaging is continued for 10 seconds to 5 minutes.

7. The method of claim 5, wherein said method is performed twice daily.

8. The method of claim 5, for treatment of a new scar, wherein said method is performed at least once a day for up to 12 weeks.

9. The method of claim 5, for treatment of an existing scar, wherein said method is performed at least once a day for up to 6 months.

10. The method of claim 5, for protecting a new scar, wherein said method is performed at least once a day for up to 18 months.

11. The method of claim 5, wherein 0.05 mL of the silicone composition is dispensed.
