As transmittance is dependent upon thickness, the thickness of each sample can be measured with calipers prior to loading in the spectrophotometer. Transmittance values can be normalized according to
  • the mask (or patch) is not pre-formed and is applied e.g., by spreading a silicone-based biophotonic composition making up the mask (or patch), on the skin or target tissue, or alternatively by smearing, dabbing or rolling the composition on target tissue. It can then be converted to a peel-off form after application, by means such as, but not limited to, drying or inducing a change in temperature upon application to the skin or tissue. After use, the mask (or patch) can then be peeled off without leaving any flakes on the skin or tissue, preferably without wiping or washing.
  • the silicone-based biophotonic composition has an adhesion strength that is less than its tensile strength or its tear strength.
  • the present disclosure provides a method for providing skin rejuvenation or for improving skin condition, treating a skin disorder, preventing or treating scarring, and/or accelerating wound healing and/or tissue repair, the method comprising: applying a silicone-based biophotonic composition of the present disclosure to the area of the skin or tissue in need of treatment, and illuminating the silicone-based biophotonic composition with light having a wavelength that overlaps with an absorption spectrum of the chromophore(s) present in the composition.
  • the silicone-based biophotonic composition may be used following ablative skin rejuvenation treatment to maintain the condition of the treated skin.
  • the silicone-based biophotonic composition may be applied at regular intervals such as once a week, or at an interval deemed appropriate by the physician.
  • Expression wrinkles result from a loss of resilience, particularly in the dermis, because of which the skin is no longer able to resume its original state when facial muscles which produce facial expressions.
  • vitamin C examples include an ascorbic acid derivative such as L-ascorbic acid or sodium L-ascorbate, an ascorbic acid preparation obtained by coating ascorbic acid with an emulsifier or the like, and a mixture containing two or more of those vitamin Cs at an arbitrary rate.
  • natural products containing vitamin C such as acerola or lemon may also be used.
  • the silicone-based biophotonic compositions and methods of the present disclosure can be used to treat one or more of skin irritation, pitting, development of scars, comedones, inflammatory papules, cysts, hyperkeratinazation, and thickening and hardening of sebum associated with acne.
  • the kit may further comprise a light source such as a portable light with a wavelength appropriate to activate the chromophore of the silicone- based biophotonic composition.
  • a light source such as a portable light with a wavelength appropriate to activate the chromophore of the silicone- based biophotonic composition.
  • the portable light may be battery operated or re- chargeable.
