Overview
DDF (which stands for Doctor’s Dermatologic Formula) was founded in 1995 by Dr. Howard Sobel, a New York City dermatologist and plastic surgeon. This company was the culmination of his more than 25 years of experience and some of his expertise, which was well known within the dermatologic community after he presided as the editor-in-chief of several professional publications. He linked up with well-known cosmetic personality Elaine Linker to create DDF, which is now a top-selling brand at Sephora stores. The company offers two formulas for the eye area: Protective Eye Cream and Bio-Molecular Firming Eye Serum.

Featured Ingredients
Protective Eye Cream is intended to protect the eye area from future damage while minimizing the look of fine lines near the eye area. It apparently contains a daily moisturizer to create these effects, but our efforts to find out any specific ingredients came up short. Therefore, we cannot evaluate the ingredients in this formula and cannot vouch for its effects. 

Bio-Molecular Firming Eye Serum was formulated to improve the overall contour of skin near the eye area by firming and lifting the skin, reducing the appearance of fine lines and improving moisture. According to the web site, this formula contains a combination of proteins, peptides (specific signaling molecules) and antioxidants. Like the Protective Eye Cream, however, it is not clear what these ingredients are, thus it is impossible for us to evaluate this formula and provide a critical analysis.

Web Site Description
The DDF Web site is clearly constructed and presented. Much of the focus seems to be on differentiating the company from other cosmetic companies, which is an important task. The product descriptions are brief and simple, but seem to lack some important information, including what the specific ingredients are, which makes evaluation of DDF products nearly impossible. All purchases are conducted through Sephora’s online store or by visiting a Sephora location near you. No free trial of products is offered.

Positives
- Dr. Sobel has an established reputation in the dermatologic field

- The company offers a full range of skincare formulas for a variety of problems

 Negatives
- Neither eye formula contains a listing of ingredients

- No free trial of product is available

- Products must be purchased from Sephora

Conclusion
Initially, we felt hopeful as we started evaluating the two DDF eye care formulas, considering Dr. Sobel’s reputation in the field. However, we found ourselves becoming frustrated at the lack of important information (such as active ingredients) about the products. Therefore, until we obtain this information, we cannot recommend any DDF products at this time.
