What is it
Generally speaking, fatty warts are not true warts but rather a lay term for sebaceous gland hyperplasia or soft fibromas. They are benign skin conditions that do not threaten health, though they may affect appearance. Detailed analysis is as follows:

Fatty warts caused by sebaceous gland hyperplasia typically result from blocked sebaceous ducts and accumulated sebum. They commonly appear on the face and neck as small, smooth-surfaced, pale yellow papules with a soft texture, usually causing no discomfort. Soft fibromas, on the other hand, are associated with skin aging and friction, frequently occurring on the neck and armpits. They present as flesh-colored or brown skin tags, soft in texture, and may slowly enlarge over time.
These benign skin conditions are neither contagious nor prone to malignant transformation. If small and asymptomatic, they generally require no special treatment. However, if removal is desired for cosmetic reasons or if irritation and bleeding occur due to friction, minimally invasive methods such as cryotherapy or laser therapy can be used. These procedures are simple, allow quick recovery, and require attention to local hygiene afterward to prevent infection.
In daily life, maintaining clean skin, avoiding frequent friction on affected areas, using gentle skincare products, and minimizing skin irritation are recommended. Regular sleep patterns and a light diet can help maintain normal skin metabolism and reduce the likelihood of developing such skin issues.
