Incisions on the breast such as mastopexy Wise-patterns, crescents, T-lifts, etc. take several months to years to mature. In general we tell patients not to apply any creams or lotions on the skin for 4-6 weeks after surgery. After six weeks, silicone sheets can be applied to the scar to flatten the scar or prevent hypertrophic scars or keloid scars. In the initial 4-6 weeks post surgery we try to avoid skin creams, as it may be difficult to determine if the skin is irritated or infected. At the one year and sometimes 2 year mark, scars can continue to fade.
