Hello and thank you for your question. Your beard is safe from damage from CO2 lasers as hair follicles lie deep under the skin away from the laser penetration. Remember to ask about pre-treatment. I find that pre-treating the skin is advantageous to better outcomes. Best of luck to you.
The fractional Co2 treatment does not go deep enough to impact your hair follicles. The hair follicle where hair growth starts is located deeper in the skin than what is being treated on the surface. However, the type of laser, depth of treatment and type of acne scar you are treating are all dependent factors as to whether damage could occur. It is recommended to have a good skin care routine ready for post-treatment. Be cautious and stay away from the sun and use lots of sunscreen.
