Dr. Corey Maas continues the conversation on fractional laser treatments, walking you through what to expect on treatment day and how to care for your skin afterward. ✨

The procedure is performed in-office, and patients can return home the same day. Post-treatment care is simple but essential: keep the skin well-hydrated with ointment, avoid sun exposure, and allow your skin the time it needs to heal and renew.

This final part ties it all together, from how fractional lasers work beneath the surface to how proper aftercare supports smoother, healthier-looking results.

Hair Grafting: fuller density, restored confidence! ✨

This advanced surgical treatment uses your own healthy hair follicles, typically taken from the back of the scalp to naturally restore thinning or balding areas. Each graft is strategically placed to rebuild density, redefine the hairline, and create a seamless, natural-looking blend with your existing hair.

By focusing on precision, placement, and long-term growth, hair grafting delivers a fuller, more youthful appearance that continues to improve month after month. It’s incredible how restoring the hairline can transform not just your look, but your confidence too.

Dr. Corey Maas breaks down one of the biggest misconceptions about rhinoplasty: it’s not about making your nose as small as possible, it’s about proportion. 👃✨

Follow along as he explains how features like your upper-lip length and the space between the inner corners of your eyes help determine ideal nose projection and width.

Curious whether rhinoplasty could enhance your proportions? Book a consultation at the link below to talk through your goals. ✨

Thread lift: refined lift, refreshed contours! ✨

This minimally invasive treatment uses dissolvable threads to gently lift, reposition, and support the skin, perfect for improving mild to moderate sagging in areas like the cheeks, jawline, and lower face. By enhancing definition and restoring youthful structure, a thread lift creates a naturally elevated look without adding volume or requiring surgery.

It’s amazing how a subtle lift can rejuvenate the entire face, showing that small, precise changes make the biggest impact. Book your consultation with us at the link below.
