We often get questions about our subject database and how we recruit for our clinical trials.  We put together a list to help answer these questions!


  1. What methods do you use?

We use a variety of channels but the most effective is word of mouth and referral.  We find that the key is to get our name out there consistently to create an awareness so we can recruit difficult eligibility requirements.  The effectiveness of each also depends upon the location.

  • Word of mouth
  • Facebook in US
  • Mixi in Japan
  • Twitter
  • Email
  • Current Database
  • Google +
  • Craigslist
  • Local blogs
  • Local magazines
  • Community Engagement Events
  • TV
  • Radio
  • Newspapers
  • Festivals

Our Japanese Research Center has a recruiting center in Ikebukuro, Tokyo, one of the most populated districts in Tokyo.

  1. How large is your database?

The numbers are approximate and are subject to change.

Dallas: 25,000

Colorado Springs: 10,500

Tokyo: 3,000

We also partner with a research site in Seoul, SK that has 10,000 subjects in their database.


  1. What is the demographic profile of your database?

This is always changing as we get studies that require different eligibility requirements. It also differs at each location but this gives a general overview.


Males: ~25%

Females: ~75%


Our subjects come from a variety of ethnic backgrounds and race, which include Caucasian/white, African American/black, Asian, Hispanic or Latino, American Indian and Mixed/Other.


3 months to 84 years old with a majority falling in the 26-55 age categories.

What conditions do they have?

Subjects in our database have a variety of conditions and below are the more common ones

  • Normal Healthy Volunteers
  • Sensitive skin
  • Dry, oily, and combination skin
  • Skin problems such as acne, pigmentation issues, melasma, rosacea, eczema, psoriasis, keratosis, hyper and mottled pigmentation, cellulite
  • Variety of aging skin conditions and levels of severity. For example photodamage, wrinkles/lines, melasma, uneven skin tone, lack of radiance and clarity, sagging skin, etc.

  1. How long does it take to recruit for the study?

It depends upon the eligibility criteria, but we make every effort to get it done as quickly as possible.  We know you have deadlines to meet!  We do block enrollment and bring groups of subjects in at one time.  This is more efficient compared to a doctor’s office, which typically enrolls 1-2 subjects at a time.

We also have an online registration process in which allows us to keep track of their contact information, demographics, what conditions they have and studies they qualified for.

Please contact us with any other questions that we might have missed.
