The choice between 16G and 18G piercings depends on several factors: Location: 16G is often better for cartilage piercings, while 18G is popular for earlobes and nostrils. Durability: 16G is generally more durable and less prone to migration. Healing: 18G typically heals faster due to the smaller hole. Aesthetics: 18G offers a more subtle look, while 16G is slightly more noticeable. Future plans: 16G is better if you plan to stretch the piercing later. Neither is universally "better" - the best choice depends on your specific needs and preferences. Consult with a professional piercer for personalized advice.
