The depressed appearance caused by scars can be reduced with hyaluronic acid, making the skin look smoother. The duration of one session may last up to 3 hours depending on the number, spread, and depth of the scars. The pain felt during the procedure usually does not exceed 3-4-5 out of 10. Redness and swelling on the skin due to the procedure usually heal in 7-14 days; rarely it may last up to 28 days. The success rate of the treatment varies depending on the type and depth of scars and the skin structure. It can be applied in every season. After the procedure, it is necessary to use an antibiotic cream and sunscreen for 7 days. The permanence of hyaluronic acid in the face may vary depending on the person’s metabolism, autoimmune diseases, and medications used. Recent scientific studies have shown that hyaluronic acid treatment for acne scars lasts at least 2 years and may create a permanent effect.
