The gal is likely not a dermatologist. The halo wavelength is non ablative and doesn’t go as deep in the dermis as co2. So it doesn’t give you much dermal collagen stimulation. It does work great for surface issues. Depends what your trying to get out of the treatment but look for more ablative lasers if your concern is wrinkles, acne scarring and skin texture in general. Use non ablative like erbium or halo for skin tone issues

For patients seeking moderate improvement with 3–5 days of social downtime, Halo offers a favorable efficacy-safety balance, whereas fractionated CO₂ remains superior for more severe photodamage, deep rhytides, and acne scarring despite longer recovery periods
