Thank you for your question regarding the fact that you had an arm lift or brachioplasty 4 weeks ago, and are using a scar silicon gel, Strataderm, once a day and whether it is better to use it twice a day. Every plastic surgeon has a specific recipe for maximizing the appearance of scars. Medical research has proven that the best topical cream for scars is silicone. Silicone is superior to vitamin E, body oils, shea butter, or coconut butter. Silicone can be applied to a scar once the incision has healed. Silicone can be directly applied to the scar. Silicon should only be applied to a scar for 12 hours a day. If silicone is applied for over 12 hours, many patients can experience hyperpigmentation. Hyperpigmentation is a condition where melanin deposits next to the scar. Melanin is the chemical that causes the skin to pigment. Unfortunately, hyperpigmentation due to silicone is difficult to treat and may require skin-bleaching creams and lasers. Therefore, you should only wear the silicone for approximately 12 hours daily. Most plastic surgeons suggest applying silicone cream to the scar. The scar is then covered with silicone gel sheeting, which is kept in place by a medical-grade compartment garment. Silicone cream, silicone gel sheeting, and arm lift garments are worn for approximately 12 hours daily. Ideally, this therapy is continued for two years. Applying silicone is necessary since the arm lift scar takes approximately two years to mature fully. In addition, you should protect the arm lift scar from the sun. Solar radiation energy can negatively impact the appearance of surgical scars. Good luck. I hope I have answered your question regarding the fact that you had an arm lift or brachioplasty 4 weeks ago, and are using a scar silicon gel, Strataderm, once a day, and whether it is better to use it twice daily. If you have any questions regarding the arm lift, arm reduction, or brachioplasty, please get in touch with an arm lift expert. Since a brachioplasty or arm lift surgery is difficult, please seek an experienced, board-certified plastic surgeon with significant experience performing these types of arm lifts. Do your research. Make sure your chosen plastic surgeon has performed at least 150 arm lifts. Make sure they have the before and after pictures to prove it. Please carefully look over their before and after pictures and check their reviews on RealSelf. Sincerely, Dr. Katzen.
