Northwest Arkansas Clinical Trials Center has been a dedicated dermatology research center for more than 7 years. The research center is located in the heart of Northwest Arkansas, home to a regional population of more than 500,000 residents and two large college campuses. The clinical trials center has over 1500 square feet solely dedicated to dermatology research and research subjects. The center includes a reception area, examination rooms, laboratory, locked and temperature monitored investigational product ambient storage, study coordinator offices, and temperature monitored refrigerator and -20 C freezer. All equipment undergoes certification annually.

The combined clinical trial team experience in phase I-phase IV studies exceeds 50 years. Investigational product formulation experience includes oral, intravenous, topical and other parenteral routes. All personnel have certified GCP training and most are IATA certified. The staff is very familiar with the variety of electronic data capture (EDC) platforms and are very proficient in data entry.

The center and personnel have clinical trial experience in the following dermatologic conditions in pediatric, adolescent and adult populations:

  • Atopic Dermatitis
  • Alopecia
  • Hyperhidrosis
  • Psoriasis
  • Acne
  • Common Warts
  • Seborrheic Keratosis
  • Rosacea
  • Hidradenitis suppurativa


Using the right sunscreen every day can reduce your risk of developing skin cancer, which is the most common cancer in the United States.


When shopping for sunscreen, your choices can feel overwhelming. You’ll find lotions, sprays, gels, and creams. With so many different SPFs, it can be hard to tell which one you need.

To make it easier to buy sunscreen, the American Academy of Dermatology is sharing a simple two-step process. Here’s what you can do to find a sunscreen that’s right for you.

Step 1: Look for the 3 essentials

To protect your skin from the sun’s harmful rays, you want to use a sunscreen that offers all of the following:

  • SPF 30 (or higher)
  • Broad-spectrum protection (UVA/UVB)
  • Water resistance

Not every sunscreen offers all 3. When it does, you’ll see the above words listed on the container. On some products, you may see the words “broad spectrum” or “UVA/UVB.”

It’s really important to use a sunscreen that offers the 3 essentials. Studies show that daily use can reduce your risk of:

  • Skin cancer, including melanoma, the most-serious skin cancer
  • Precancerous skin growths that can turn into skin cancer
  • Signs of premature skin aging like age spots, wrinkles, and leathery skin
  • Sunburn
  • Melasma
  • Dark spots on your skin that can appear when acne, psoriasis, or another condition clears

Step 2: Consider your skin type, skin conditions, and other needs

By limiting your sunscreen choices to ones that contain the 3 essentials, you’ll still have quite a few options. To find a sunscreen that’s right for you, you’ll want to consider your skin’s unique needs and where you want to apply the sunscreen.

The following list can help you narrow your options so that you can find a sunscreen that’s right for you.

Acne-prone skin: Look for the words “non-comedogenic” or “won’t clog pores".

Allergy-prone skin: Avoid sunscreen that contains fragrance, PABA, parabens, or oxybenzone (benzophenone-2, benzophenone-3, diosybenzone, mexenone, sulisobenzone, or sulisobenzone sodium).

Around your eyes: To prevent sunscreen from dripping into your eyes, use a sunscreen stick around your eyes. Make sure the stick has an SPF 30 (or higher), broad-spectrum protection, and water resistance.

Children: Use a sunscreen made for children. Most contain zinc oxide and titanium dioxide.

Dry skin: Look for “moisturizing” or “dry skin” on the label.

Lips: Lip balm with SPF 30+ and broad-spectrum protection.

Oily skin: Look for the words “non-comedogenic” or “won’t clog pores.”

Olive to darkly colored skin: Use sunscreen with a tint to prevent a white reside from forming on your skin.

Rosacea: Use a sunscreen that contains only zinc oxide and titanium dioxide. Many sunscreens for children contain only these 2 ingredients.

Sensitive skin: Use a sunscreen with the words “sensitive skin” on the label. Avoid products with fragrance, parabens, or oxybenzone (benzophenone-2, benzophenone-3, diosybenzone, mexenone, sulisobenzone, or sulisobenzone sodium).

Skin stings or burns when you apply sunscreen: Use a sunscreen that contains only zinc oxide and titanium dioxide. Many sunscreens for children use only these 2 ingredients. Avoid sunscreen with fragrance.
