Raised hypertrophic scars. Does kenalog/5-FU or 1540 non-ablative/IPL combo work better?

Intralesional Kenalog, either alone or in combination with 5-FU, a relatively inexpensive treatment approach for this kind of problem, has proven itself a tried and true treatment modality for hypertrophic scars, in particular, as well as for keloids, for decades. I have personally used this simple approach for over thirty years myself. In comparison, relatively expensive, and heavily marketed and advertised light and energy-based therapies for these same purposes are comparative newcomers on the scene, and, as for just about all of their purported virtues for many indications, have yet to be fully proven through rigorous science. Make sure that you consult a board certified aesthetic physician with experience and expertise in treating hypertrophic and keloid scars. Best of luck. 

Scar treatment at this point is a little like cooking - a little of this and a little of that. There are studies that show benefit of each of the modalities - different lases and injectables but I don't know of any that compare different combinations of therapy. If a scar is raised and not red I use a fractional erbium laser (Sciton Profractional) with or without steroids/5FU - depends on the thickness etc. For red scars I use a vascular laser - I like IPL/BBL but other vascular lasers are excellent as well. Combinations of these therapies are also used depending on the scar and previous treatments. Scar revision is also used first if the scars are terrible and lasers/injectables are used in the healing phase. Best to see a doc who has experience and a variety of devices/lasers

Thank you for your question. This will take a combination of V-Beam laser and cortisone injections to treat keloid scars. It typically takes several sessions to help minimize and flatten the scars. I recommend having a consultation with an expert to determine the best treatment plan for you. Best of Luck!
