How can I remove a bump/lesion and atrophic scar on my nose? (photos)

The treatment of scars on the face and body follows a protocol-based approach in our office. We start by characterizing the scars in terms of redness, atrophy, hypertrophy, size, volumetric biometrics, and color hyperpigmentation and then devise a customized protocol for you. Our Hidef scar protocol uses micro fractional and fractional RF, fractional laser, sublative RF, vbeam therapy, injection based IIT, and scar modulation. Scars that exhibit growth should begin treatment with Plato's Scar Serum twice daily followed by Melarase AM and Melarase PM for dark and discolored scars.

There are a couple different ways that this scar can be treated. Perhaps the best way would be to excise the scar and then reconstruct it. This would leave a fine, thin line, but this area tends to heal very well.
Another option would be a CO2 laser to smooth and tighten the skin as well as to produce collagen to help fill in any depressed areas.
I personally recommend seeking out an experienced facial plastic surgeon.
Please let us know if you have any other questions or concerns.

this needs laser treatmenets and TCA cross, not easy to treat. needs an expert. at home cosmelan peels and dermarolling will get you ready for treatment (see emeragecosmetics.com which you should do weekly anyway).
Acne scar treatment needs a combination approach for improvement.  For the best results, one should target the acne scar type.  As everyone has a unique pattern of acne scarring, the best solution is a tailored one.  Typically you need fillers like bellafill and sculptra for atrophic indented type scars with or without subcision.  Subcision for depressed tethered scars.  Vascular lasers like yellow laser, aerolase, excel V or IPL for redness or thick scars. And lasers such as fraxel, erbium, co2 or fractional radiofrequency like venus viva, skinfinity, intensif or fractora microneedling RF for textural issues and superficial scarring.  Deep ice pick scars and narrow box car scars are best treated with TCA CROSS and punch excision.  All lasers are combined with microneedling and PRP to get even better results and improve healing times.   The majority of patients will have a collection of different scar types, and hence a tailored treatment plan is needed by an expert physician.  It is never about the laser or product that gives the results, its about the expert behind the equipment that gets you the outcome.  Scars cannot be cured and will need life-long treatments to maintain and build on the results.  For those at high risk for hyperpigmentation (darker skin types or asian or hispanic or mixed ethnicities) we already pre-treat the skin with cosmelan or enlighten lightening peels to prevent complications from energy-based or chemical-based treatments.  Best, Dr. Emer.
