Differences between Forever Young BBL and Halo?

Halo may not have been suggested if the office didn't have that technology. We use both daily, think they are both wonderful, but do different things that complement each other. We almost always combine the two to get people the very best results with no more downtime than Halo alone.
BBL is best in class treatment for color (browns and reds) and antiaging (if done regularly, like exercise, research at Stanford shows reversal of skin aging). It's limitations are that you can't treat eyelid skin and that it only offers minor improvement in texture, wrinkles and laxity. For these, if you have moderate downtime, Halo is great as you can treat both eyelids right to the lashes and also fine lines / wrinkles. Finally, if you are looking for maximal results with wrinkles, texture and laxity, deep full-field resurfacing is the gold standard.

Thank you for your question.  Forever Young BBL (broad band light) is a brand name IPL (intense pulsed light) device.  BBL/IPL uses pulses of very bright, focused light to treat a variety of skin conditions, including sun damage, freckles, redness, broken blood vessels, acne, and excess hair growth.  The settings used during Forever Young treatments are specifically designed to target sun damage and red/brown pigment in the skin.  The device manufacturer markets it as "Forever Young" because some studies have shown that patients who receive regular BBL/IPL treatments over the course of several years do see some improvement in skin texture as well.  That said, these treatments are still best suited for treating pigment.
Halo is a newer laser device, made by the same company that manufacturers Forever Young.  Halo is fairly novel, as it actually combines two different laser wavelengths, that target the skin at different levels.  One wavelength actually partially ablates the superficial layers of the skin (great for pigment and fine lines), while the other heats the deeper layers of the skin (for longer-term collagen stimulation).  Halo is primarily designed to improve skin texture, pore size, etc.  In our clinic, we own both Forever Young BBL and Halo, and we often perform both treatments at the same time, to optimally improve both pigment and skin texture.
It's impossible to make exact recommendations without examining you, so I can't comment as to why your provider did not offer you Halo.  There are also a multitude of other laser devices designed to help with skin texture and laxity.  I would recommend scheduling an appointment with a cosmetic dermatologist or plastic surgeon to discuss the best treatment plan for you.  Best of luck!
