Brief Summary:
The study is to compare the expression of both keratin 16 and 17 before and after application of sulforaphane on both photoprotected and photoexposed area, and to determine whether these findings alter skin aging as well as skin response to ultraviolet (UV) and visible light exposure.

Condition or disease Intervention/treatment Phase
Skin Aging Drug: Sulforaphane (broccoli sprout extract) Radiation: UV or visible light Early Phase 1

Detailed Description:

The study is to compare the expression of both keratin 16 and 17 before and after application of sulforaphane on both photoprotected and photoexposed area, and to determine whether these findings alter skin aging as well as skin response to ultraviolet (UV) and visible light exposure.

Each study participant will have up to eight study visits. Topical sulforaphane will be applied for up to 6 months. Photography, clinical assessment, UV light irradiation, Visible light treatment, Skin biopsies, non invasive elasticity measurements such as cutometer and ballistometer, and others will be involved in this study.

Arm Intervention/treatment
Active Comparator: Sulforaphane without light challenge
Participants with moderate photodamage and moderate intrinsic skin aging will apply sulforaphane (broccoli sprout extract) in jojoba oil nightly (without any UV or visible light irradiation) for up to 6 months and have up to 9 biopsies taken just before treatment and occurring at regular intervals during the study
Drug: Sulforaphane (broccoli sprout extract)
Participants will topically apply Sulforaphane for a period of time

Active Comparator: Sulforaphane with light challenge
Participants will have 2 test areas irradiated with up to 5 UV or visible light treatments and biopsies taken before and within 7 days after UV or visible light irradiation; one of the UV/visible light treated areas will be pre-treated with sulforaphane (broccoli sprout extract) for up to 28 consecutive nights and the other UV/visible light treated areas will be pre-treated with jojoba oil.
Drug: Sulforaphane (broccoli sprout extract)
Participants will topically apply Sulforaphane for a period of time

Radiation: UV or visible light
Participants will have 2 test areas irradiated with up to 5 UV or visible light treatments




Primary Outcome Measures :
  1. keratin 16 presence as determined by immunofluorescence assay [ Time Frame: Up to 6 months ]
    The investigators will detect the presence of keratin 16 in the basal layer of the epidermis in both photoprotected and photodamaged skin treated with sulforaphane (SF), by immunofluorescence assay, to determine whether SF can improve skin fragility and other features seen in these conditions

  2. keratin 17 presence as determined by immunofluorescence assay [ Time Frame: Up to 6 months ]
    The investigators will detect the presence of keratin 17 in the basal layer of the epidermis in both photoprotected and photodamaged skin treated with SF, by immunofluorescence assay, to determine whether SF can improve skin fragility and other features seen in these conditions

  3. keratin 16 fold change as determined by Reverse Transcription Polymerase Chain Reaction (RT-PCR) [ Time Frame: Up to 6 months ]
    The investigators will detect the fold change of keratin 16 in the basal layer of the epidermis in both photoprotected and photodamaged skin treated with SF, by RT-PCR, to determine whether SF can improve skin fragility and other features seen in these conditions

  4. keratin 17 fold change as determined by RT-PCR [ Time Frame: Up to 6 months ]
    The investigators will detect the fold change of keratin 17 in the basal layer of the epidermis in both photoprotected and photodamaged skin treated with sulforaphane (SF), by RT-PCR, to determine whether SF can improve skin fragility and other features seen in these conditions


Secondary Outcome Measures :
  1. keratin expression changes as determined by RT-PCR [ Time Frame: Up to 6 months ]
    The investigators will test the fold change of keratin expression in human skin after acute UV and visible light light exposure, separately and in combination with application of topical sulforaphane by RT-PCR.
