    Sunscreens

    Go to Top

    Sunscreen products are often tested to determine their water-resistant properties, their potential for skin and/or eye irritation, and/or their ability to provide protection from the sun. Studies are conducted at both indoor and outdoor facilities, and may require subjects to immerse themselves in water.




    Soaps and Cleansers

    Go to Top

    Personal cleaning products, including bar soaps, liquid soaps, body washes, and laundry detergents may be tested to determine their effectiveness and/or their potential for skin and/or eye irritation. These studies may be conducted at our test facility, or designed as in-home use studies.




    Deodorants

    Go to Top

    Deodorants are tested to determine their ability to control underarm odor. Subjects in deodorant studies are usually required to refrain from using deodorants for 5 to 10 days prior to study participation. In these cases, Hill Top Research will supply the study subjects with a soap product, to be used in place of their normal deodorant.




    Moisturizers and Lotions

    Go to Top

    Moisturizers and lotions are commonly tested to determine their effectiveness at moisturizing the skin. Moisturizers may also be tested to collect information on product characteristics such as scent and texture.




    Cosmetics and Cosmetic Removers

    Go to Top

    Cosmetic products used or applied close to the eyes are tested to determine their potential for causing irritation to the eyes or surrounding skin. These studies are generally available only to female study subjects, and may or may not include contact lens wearers.




    Antiperspirants

    Go to Top

    Antiperspirants are tested to determine their ability to reduce underarm perspiration. Subjects in antiperspirant studies are usually required to attend several study sessions in a temperature and humidity controlled environment. Subjects must refrain from using antiperspirants for 17 to 30 days prior to study participation. In these cases, Hill Top Research will supply the study subjects with a deodorant product that has no antiperspirant properties.




    Shampoos

    Go to Top

    Hill Top Research tests a variety of shampoo products, including those designed to control dandruff and/or moisturize the scalp. Shampoo studies typically involve a longer time span, and may be conducted on site at our facility, or designed as an in-home use study.




    Acne Treatments

    Go to Top

    Clinical studies testing the effectiveness of acne treatments may include both adult and teenage participants. In most cases, study subjects are provided with an acne treatment to use at home, and are required to make return visits to our facility for evaluation.




    Feminine Hygiene Products

    Go to Top

    Products designed specifically for women are tested at Hill Top Research. These may include products designed to provide everyday dryness, freshness, protection, and moisturization.




    Medicated and Non-Medicated Patches

    Go to Top

    Patch studies are often conducted to evaluate the potential for skin irritation or allergies to the products contained on the patches and/or to evaluate the adhesive properties of the patches. Subjects participating in patch studies are typically required to wear several patches on their arms, backs, shoulders, or abdomens, for a predetermined period of time, returning to our facility periodically for evaluation.




    Medicated Ointments, Creams, and Gels

    Go to Top

    Hill Top Research tests a variety of creams, ointments, and gels containing pharmaceutical ingredients. These tests, designed to help researchers develop products for those who suffer from irritating skin conditions, are most often conducted on subjects with healthy skin. These studies usually require an overnight stay at our facility.




    Generic Medications

    Go to Top

    Generic medications are tested to verify their equivalency to marketed name-brand medications. These studies require multiple overnight visits, during which the study subjects will be monitored, including periodic blood draws. Subjects participating in generic medication studies will receive a physical prior to participation.




    Medical Devices

    Go to Top

    Medical devices, especially those that are designed to stick to the skin, are tested to evaluate their adhesive properties and/or potential to cause skin irritation. Subjects participating in medical device studies may be required to wear a non-medicated adhesive product, typically on the back or abdomen, for a predetermined period of time, returning to our facility periodically for evaluation.




    Cold Sore Treatments

    Go to Top

    Cold sore treatments are tested to determine their effectiveness at reducing healing time, or preventing reoccurring outbreaks. These tests may be conducted on subjects with or without active lesions. In most cases, study subjects are provided with an cold sore treatment to use at home, and are required to make return visits to our facility for evaluation.




    Wound Care and Wound Healing Products

    Go to Top

    Products designed to protect wounded skin and/or aid in the healing process, like adhesive bandages, are tested to determine their effectiveness and/or their potential to cause skin irritation. These studies often require subjects to receive superficial abrasions to small areas of skin, and submit to photographs of the abraded areas.
