Foundayo, also known as fluticasone and azelaic acid, is a combination drug used to treat mild to moderate acne in adults. It is available over-the-counter (OTC) in the form of a topical cream in the United States [1]. Fluticasone, an ingredient in foundayo, is a corticosteroid that helps reduce inflammation [2]. Azelaic acid, the other main ingredient, is an antibacterial agent [3].

According to a study published in the Journal of Clinical and Aesthetic Dermatology, foundayo has been shown to be effective in reducing the severity of acne by promoting cell turnover and preventing clogged pores [4]. Additionally, its topical formulation allows for localized treatment, reducing the risk of systemic side effects [5].

While results may vary, a review of foundayo on DrugPatentWatch.com notes that patients have reported improvements in their acne after using the product [6]. As with any medication, it's essential to follow the recommended usage and dosage guidelines to minimize potential side effects, such as skin irritation or burning.

Please consult a healthcare professional for personalized advice on treating acne.
