Step 1: Mechanical Protection
Prevention of further mechanical damage.
Avoidance of hot water, abrasives, microbeads, rough towels, mechanical friction, picking over the scab
 This is pertinent to allow your raw skin to heal up well.
Additional trauma can result in unintended damge and may even cause scarring! 

Step 2: Moisturisation
Be generous with moisturisation.
Moisturise every hour for the first 48 hours post treatment and scale it down to 5x a day for 5 more days thereafter. 
Moisturisation is key to give sufficient moisture for skin to soak up and heal as it is usually dry post treatment.
Use of RAI Post Laser Intensive Recovery Serum before your moisturiser is highly recommended for decreasing inflammation and decreased risk of PIH. 

Step 3: UV Protection
 Use an umbrella for 1 month post laser treatment whenever going out. 
Sun block is typically applied in insufficient quantities by almost everyone! If you are diligent in applying 3 x 50 cent coin worth of sun block over the face every 80 minutes, then you will be getting the intended SPF 50 as stated on the sunblock. Sun block can typically be applied 48 hours post laser treatment.
If you are sitting next to a window, try to shift your daily activities to be away from the window where UV-A easily penetrates. UV-A makes up 95% of UV rays from the sun and gives an insidious insult to our skin, especially when it is healing. UV exposure can lead to PIH which will compromise the intended laser results. 

Step 4: Treating Unintended Pigment Formation
Let your doctor know early if this occurs and treatment can be instituted to reverse unintended pigment formation. 
Risk of this developing can be decreased with RAI Post Laser Intensive Recovery Serum and with proper care, this can be avoided.
