Abstract
System and methods for treating and shaping a keratin fiber are provided. A light-based system includes an activation system configured with one or more light source. The light source is configured to apply electromagnetic radiation at a target region including the keratin fiber. The light-based system applies the electromagnetic radiation to the target region to effectuate photocrosslinking with the assistance of a photosensitizer on the keratin fiber and transition the keratin fiber from a first physical state to a second physical state.
Claims39
A method of performing a cosmetic treatment, the method comprising:
- (a) applying a photosensitizer to a keratin fiber of a subject while the keratin fiber is in a first physical state;
- and
- (b) subjecting the keratin fiber and the photosensitizer to electromagnetic radiation selected to effectuate photocrosslinking or photoactivation on the keratin fiber to cause the keratin fiber to transition to a second physical state that is different than the first physical state.
A light-based system for treating and shaping a keratin fiber, the system comprising:
- a fluid supply system comprising a vessel in fluid communication with a fluid outlet, wherein the vessel is configured to contain a photosensitizer and the fluid outlet is configured to dispense the photosensitizer at a target region that includes the keratin fiber;
- an activation system configured with one or more light source, the light source configured to apply electromagnetic radiation at the target region;
- and
- a processor having a memory and configured to be in electrical communication with the activation system, the processor being configured to implement stored instructions from the memory to cause the activation system to apply the electromagnetic radiation to the target region to effectuate photocrosslinking on the keratin fiber to cause a transition from a first physical state to a second physical state.
