Microencapsulated Benzoyl Peroxide May Help Improve Rosacea Symptoms
A small study looked at how a specific type of benzoyl peroxide, microencapsulated, affects the skin microbiome and rosacea symptoms in people with facial rosacea. Researchers found that using this type of benzoyl peroxide may lead to improvements in rosacea symptoms, but the study was short and more research is needed. The study also found that the skin microbiome changed in response to the treatment, but it's not clear if this is a cause or effect.
Why it matters: Understanding how different treatments affect the skin microbiome and rosacea symptoms may help develop more effective treatments for this condition.
This study had a short duration and a small sample size of 31 participants, which may not fully capture the long-term effects and durability of microencapsulated benzoyl peroxide in real-world clinical practice.

Cosmetic Dermatologists Recommend Top Skincare Ingredients
Researchers studied which skincare ingredients are recommended by cosmetic dermatologists for common skin concerns like fine lines, acne, and dry skin. A panel of dermatologists narrowed down a list of 318 ingredients to 23, which they agreed are most useful. These ingredients include azelaic acid, benzoyl peroxide, and vitamin C.
Why it matters: This study may help consumers understand which skincare ingredients are backed by expert opinion and have some scientific evidence to support their use.
Some ingredients were based on expert opinion rather than published evidence, and the study did not evaluate the effectiveness of these ingredients in real-world use.

Encapsulated Benzoyl Peroxide May Help Elderly Rosacea Patients
Researchers studied a cream containing encapsulated benzoyl peroxide to treat rosacea in people under and over 65. They found that the cream may be effective in reducing symptoms in both age groups. However, more research is needed to confirm these results.
Why it matters: This study may help skincare professionals understand how to treat rosacea in elderly patients more effectively.
This analysis pooled results from two 12-week trials with 733 subjects, but the study did not compare encapsulated benzoyl peroxide to nonencapsulated BPO.
