Fatty granules refer to milia. Milia are benign lesions that generally do not require treatment, and if treatment is needed, they can be treated by picking them with a needle and squeezing out the contents or by utilizing physical treatments such as electrocautery or lasers.
Corns are tiny cysts formed by the retention of epithelial keratin material in the ducts of the skin or hair follicles and other skin appendages, which are benign lesions with no conscious symptoms and generally require no treatment. If fat grains on the neck affect the aesthetics and there is a need for treatment, they can be treated by picking the cyst with a needle after sterilization and squeezing out the contents inside.
Physical therapy such as electrocautery and laser can also be used to assist in the treatment. It is important to keep the skin dry and clean on a daily basis and avoid using irritating cosmetics that may damage the skin. The treatment of milia should be carried out under the operation of professionals, not self-operation, to avoid secondary infection.
