Is it normal to not have a sandpaper like texture after 2nd treatment of Clear + Brilliant even though I did with 1st treatment?

Not necessarily because recovery can vary. For best results with Clear + Brilliant, I recommend a a combination approach with:
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 regularly and a few times a year Fraxel, Viva, Co2/Erbium
4) Sculptra injections a few times a year for collagen production
5) thermage/ultherapy for yearly skin tightening
Best, Dr. Emer.

It is common not to have a sandpaper like texture on your second treatment of Clear+ Brilliant.  The outer layers of the skin may have been shed with the first treatment.  Your skin is subsequently in better condition for the second treatment, which will cause it to not take on the sandpaper-like texture.  You will still experience the full results from your Clear + Brilliant treatment; additionally, the benefits from these treatments are cumulative.  Should you continue to have further questions, there is no substitute for an in-person consultation with an experienced certified provider to go over your treatment goals and the best ways in which to achieve them.
