Hi I’m Dr Peterson, a board‑certified dermatologist — great question. Between Fraxel Dual and Halo, both are fractional lasers that stimulate collagen, improve fine lines, texture, and pigmentation, but they aren’t identical: Halo is a hybrid fractional laser that delivers both ablative and non‑ablative energy in the same session. That means it resurfaces some of the top layer of skin and heats deeper layers to stimulate collagen, giving more dramatic results in fewer sessions for wrinkles, pigmentation, texture, and pores. Many dermatologists find that Halo can produce noticeable improvement after just 1–2 treatments because of this combination. Fraxel Dual uses non‑ablative wavelengths only that heat deeper skin to stimulate collagen and improve tone and texture. It works very well for pigmentation and fine lines but typically requires multiple sessions (3–5) to achieve similar improvement. In practical terms: • Halo tends to be more aggressive per session for deeper collagen stimulation and pigment issues, with moderate downtime (redness/peeling for a few days), and often faster visible results. • Fraxel Dual is still very effective but usually more gradual with a treatment series, and downtime is similar or slightly less depending on settings. Which is “better” depends on your goals and downtime tolerance. If you want more dramatic improvement with fewer sessions, many dermatologists prefer Halo. Fraxel is a great option too, especially if you’re targeting fine lines, pigmentation, and texture but want a slightly more incremental approach. For either laser, seeing a board‑certified dermatologist in person ensures the right settings and plan for your skin type, tone, and goals.
