Studies indicate that undergoing four microneedling sessions, spaced one month apart, can result in up to a 400% increase in collagen and elastin deposition six months post-treatment. However, the required number of sessions varies from person to person. While some individuals may achieve desired results after just one session, others with more significant concerns may opt for a longer series of treatments. For optimal outcomes, a series of four treatments, spaced 4-6 weeks apart, is recommended for skin rejuvenation. For moderate to severe acne scarring or deeper wrinkles/sun damage, a course of 4-6 sessions, also taken 4-6 weeks apart, is advisable.
