Large, painful, inflamed bumps under the skin, also known as cystic acne, can often be uncomfortable and more difficult to treat than other pimples. The key indicator of cystic acne is feeling it under the skin. However, only a red mark and raised bump appear on the surface. According to experts, cystic acne that develops deeper in the skin doesn't always come to the surface. It can also be more inflammatory and has a higher potential to leave a scar. Therefore, visiting a dermatologist is necessary to prevent scarring while treating this skin condition. Treatment options for cystic acne often include prescription-grade products. The key to remember while going through treatment is patience, consistency, and proper at-home care with a good skincare routine.
