Psoriasis, rosacea and acne are chronic conditions of the skin, causing redness, irritation and inflammation. While these conditions have separate underlying causes, some of the same remedies may work to relieve the bothersome symptoms of all three conditions.
Oral Antibiotcs
Oral antibiotics are effective prescription medications for the treatment of acne and rosacea. Medications like tetracycline, minocycline and erythromycin work from the inside to calm inflammation and kill bacteria.
Oral Retinoids
Oral retinoids can be used to treat severe rosacea, psoriasis and cystic acne, usually as a last-resort medication when other options fail. Serious side effects are related to these drugs.
Salicylic Acid
Salicylic acid is a widely used acne treatment found over-the-counter in topical creams and washes. According to the Mayo Clinic, salicylic acid may also help reduce itching and scaling occurring with psoriasis.
Topical Retinoids
Topical retinoid creams are commonly used for the treatment of acne, psoriasis and rosacea. They work by normalizing skin cell activity and are available by prescription.
Light Therapy
Light therapy is used to treat a host of skin conditions like acne, psoriasis and rosacea. This treatment is done in a dermatologist's office and can be combined with other treatments, such as oral and topical medications.
