I had cleft lip surgery when I was born and have a chicken pox scar which is 27 years old. How can I get clear skin?

Our Hidef protocols for scar revision can address different types of scars, depending on your scar biometrics and characteristics. Protocols vary in duration based on the severity of your scars. 
Bad scars can manifest in many different ways, including pigmentation, thickening, and depression of atrophic scars. Thick scars are best treated in my practice with IIT, cortisone injections, pressure management, and laser. We recommend daily use of Plato’s Scar Serum to the scars to mediate scar hypertrophy. 
Hyperpigmented scars respond well to Melarase AM and Melarase PM creams. If the area is large, consider Luminase and Exfolase creams for the body. Hyperpigmentation PIH can also be treated with Q switch laser, PICO, chemical peels, and rapid scar exfoliation. PIE erythema scars are best treated with pulsed dye laser. 
Keloid scars are our specialization. We manage small and large keloid scars with excision, IIT, PRP, laser therapy, and scar modulation. Use Plato’s Scar Serum daily. 
Textural scars respond well to nanofractional RF and fractional laser to help improve surface texture. When combined with scar modulation, the results can improve dramatically. The most important variable is for you to choose a plastic surgeon with expertise in laser therapy using Hidef protocols.

These scars can be improved with laser spot treatment, fillers, microneedling/prp and subcision to help texture and blending. I recommend getting a formal evaluation with a scarring expert. Best, Dr. Emer

You would be a great candidate for microneedling with prp.The treatment smooths and blends skin color changes, over multiple treatments.Best. Dr Brecht
