Brief Answer:
Red light and lasers are not harmful to our face or body.

Detailed Answer:
Thanks for writing to HealthcareMagic,
I've gone through your query and understand your concern,

Red light and lasers are not harmful to our face or body but it may cause temporary damage to our retina if it exceeds safe limit.
Temporary exposure up to 5 milliwatts is considered as safe limit(if it is directly focused to our eyes) and our eyes can be protected by blink reflex.
Beyond 5 milliwatts,blink reflex of our eyes can't protect from harmful effects of red light/laser.
Most laser companies comply this safe limit.

Diffuse red light is not harmful to our body.

Hope I have answered your query.
