No mends after Halo treatment: does this mean the laser wasn’t strong enough?

yes you need to go stronger, add BBL and MNRF or MN with PRP. add aerify right after see my IG we do this protocol to get enhanced results.

at home peels like cosmelan, enlighten and aerify along with dermarolling (EmerageSkin roller with anteage AERIFY MD ampules weekly, see link) should be started now to prevent further aging.

For facial rejuvenation, I would suggest a combination approach of
1) skin care with products and PRP/microneedling
2) PDT light therapy few times a month with growth factors
3) laser treatments like clear and brilliant or moxi regularly and a few times a year Fraxel/halo Viva, Co2/Erbium
4) Sculptra injections a few times a year for collagen production with fillers like juvederm/restylane/belotero/radiesse/bellafill
5) thermage/ultherapy for yearly skin tightening with or without PDO or cone based instalift threads for lifting
6) botox every 2-3 months to stop movement lines and prevent lines at rest
7) deep microneedling RF like Fractora/morpheus8/pixel8 for tightening of the skin
8) Vascular laser like vbeam/excel V or BBL forever young treatment every quarter (3-4 months)
