Retinoids are a family of vitamin A derived compounds used in dermatology to unclog pores, speed skin cell turnover and support collagen. They are a mainstay of acne treatment and are also used for sun damage and skin texture concerns.
In Australia, milder retinoid products are available over the counter, while stronger topical and oral forms are prescription only. Oral isotretinoin in particular requires medical supervision, regular reviews and strict precautions during pregnancy planning, so a doctor consultation is the required first step.
