Intervention: 0.5% hydrocortisone, silicone, vitamin E lotion; Onion extract gel; Cetearyl alcohol lotion
Intervention description: 0.5% hydrocortisone, silicone, vitamin E lotion will be applied topically to cover the selected scar twice daily for 16 weeks.

Summary:

      Keloids are thought to result from derailments in the typical wound healing process following
      cutaneous injury. Current treatment options for keloids include intralesional
      corticosteroids, silicone gel sheeting, compression, surgery and adjuvants to surgery,
      including radiation and cryotherapy.

      0.5% hydrocortisone, silicone, vitamin E lotion (HSE) and onion extract gel (OE) are widely
      used over-the-counter medications for the treatment of keloids and hypertrophic scars.
      However, their efficacy and safety have not been compared in a blinded, placebo-controlled,
      prospective fashion. This study is being undertaken to determine the efficacy and safety of
      HSE versus OE versus placebo (Cetearyl alcohol; CEA) in subjects with hypertrophic scars and
      keloids.

      This is an investigator-blinded study, which means that the doctor evaluating you will not
      know if you are receiving the study medication or not. Another doctor will be supplying you
      with the medication and discussing any problems that you may have with the medication.

      You will be assigned to one of the three treatment groups: HSE, OE, or CEA. The group will be
      assigned by chance and you will have two in three chances of receiving treatment with a study
      medication, HSE or OE. The no treatment group will receive CEA, a bland lotion, containing no
      active ingredients such as steroids, silicone, vitamin E, or onion extract.
