In some cases, acne can have long-term effects on the skin and overall health. Some of the most common long-term effects of acne include: Scarring: Severe acne can lead to the development of scars, which can be permanent and may require treatment. Hyperpigmentation: Acne can cause dark spots or hyperpigmentation on the skin, which can be difficult to treat and may take several months or even years to fade. Emotional impact: Having acne can also have a negative impact on one's self-esteem and confidence, leading to depression, anxiety, or other mental health issues. Physical discomfort: Acne can be painful and cause physical discomfort, especially if it involves large, nodular or cystic lesions. It's important to seek treatment for acne as soon as possible to reduce the risk of long-term effects and promote healthy, clear skin. Treatment can also help to manage the emotional impact of acne and prevent or treat any associated scars or hyperpigmentation.
