Dr. Zoe Diana Draelos of Dermatology Consulting Services in High Point, N.C., assessed the ingredient efficacy on aging skin in a variety of cosmeceuticals.

The study, published in the Journal of Cosmetic Dermatology, found that skin surface irregularity can be improved through the topical application of niacin, while the appearance of fine lines can be diminished through the application of moisturizers containing engineered peptides and over-the-counter retinoids.

The study also said skin pigmentation can become more regular with the use of photoprotective ingredients, while combining cosmeceutical ingredients in a moisturizing agent can magnify benefits and improve skin appearance.

"Evidence-based cosmeceutical ingredients can provide anti-aging benefits," Draelos said in a statement. "This new generation of cosmeceuticals can provide valuable skin benefits."
