Here's a guide to SL heals and what you can be looking forward to once you ding L175.
(I should give credit to the veteran Doctors who found out about these issues back in the early day of Shadowlands)
General rules/facts about SL Heals:
1) When an SL heal is executed, it heals target for it's 'Base Heal' value, then increases the max+current HP of the target by it's 'Temp HP' value.
2) The 'Temp HP' is actually a buff that lasts 12s, and cannot be overriden by a 'Temp HP' buff from a higher SL Heal. Otherwise the Temp HP expires after 12s. (See later explanation on the exceptions for the L175 heal)
3) The 'Temp HP' buff works on L165+ toons for the Cellular Recuperation.
For Assuage Pain, L195+ toons, and all other SL Heals required Target L201+ for it to work. Otherwise you only heal for the 'Base Heal' value.
4) SL Heal nanos are not rollable, nor are they known to drop from mobs or chests. They must be purchased from a specific SL Garden by someone with the appropriate Garden Key. Pandemonium Garden nanos do not require a key to purchase the nano.
