This is the least severe form of acne. It's characterized by occasional pimples, blackheads, and whiteheads that appear mainly on the face. The breakouts are usually not inflamed, and there's minimal, if any, discomfort. Many people experience this form of acne, especially during adolescence. Good skincare routines, including regular cleansing and medical-grade acne treatments, can control Grade 1 acne.

Grade 2 acne is a more persistent and noticeable form of the condition. It's characterized by frequent breakouts of blackheads, whiteheads, and pustules (pimples that have come to a head). The skin may appear red and inflamed around the breakouts. This grade of acne may require more targeted medical-grade treatments, for example: Higher potency salicylic acid, and sebum regulating agents.

This grade of acne is more severe and is characterized by numerous inflamed pustules and papules (red, tender bumps), which can appear on the face, back, and chest. The skin often looks red and inflamed. There's a higher risk of scarring with Grade 3 acne, so it's important to seek professional medical advice. Treatments may include prescription topical treatments with a strict routine using targeted medical-grade product formulations.

Grade 4 acne, also known as cystic acne, is the most severe form of the condition. It's characterized by numerous large, painful, inflamed nodules and cysts, which can lead to significant scarring. This type of acne can affect large areas of skin and can be resistant to over-the-counter treatments. It's important to seek help from a dermatologist, who may recommend treatments such as oral antibiotics, hormonal treatments, or isotretinoin (a powerful acne medication), together with a strict routine using targeted medical-grade product formulations.
