Daily use of skin care products may reduce the incidence of rosacea in patients with acne, according to results of a study published in the Journal of Cosmetic Dermatology.
Studies have shown an increase in the coincidence of acne and rosacea, but the clinical features and cause of this co-occurrence have not yet been determined.
To investigate the classification and severity of women with combined acne and rosacea, data from 563 patients was analyzed. Women 15 to 50 years of age who had both acne vulgaris and rosacea were included. The mean age of included individuals was 23.2±43 years of age. In all, 73.4% of patients presented with erythematotelangiectatic rosacea (ETR), and more than half of patients presented with ETR and severe acne.
A higher incidence of rosacea, especially ETR, was found in patients who rarely used skin care products compared with those not using skin care products (P =.017). The frequency of make-up and skin care product use, family history, and acne onset age were associated with an increased risk for rosacea in patients with acne (P <.05). Patients with acne and a family history of rosacea had a 0.381 times higher risk for ETR than those without family history (P =.04). Patients with who did not use skin care products experienced a 12.79 times higher rate of combined ETR than those who did (P =.014).
The results of this study showed the investigators the rate of coincidence of acne and rosacea as well as the importance of skin care products in the prevention of rosacea for individuals with acne. ETR was by far the most common form of rosacea, followed by papulopustular (22.73%) and phymatous rosacea (3.9%).
Limitations to this study include its targeted scope of patients with both acne and rosacea, as well as the inclusion of only women in South China.
For patients with acne without family history of rosacea, dermatologists should educate patients as to potential triggers of rosacea, the study authors cautioned. Future research investigating the rate of rosacea with acne in other demographic areas are warranted. Genetic and environmental factors influencing the development of rosacea also warrant investigation, they suggest.
