I bought this to reduce downtime at a beauty clinic. I used it at my own risk after a Ruby Fractional treatment. I actually wanted a La Roche-Posay mask, but they were nowhere to be found... (maybe only available online?), so I used this instead. It calms the stinging and dryness, and is pretty good. I applied La Roche-Posay cica cream after this. I think it was a good combination. It's recommended to use it about once a week, so I'll use it again if I have downtime.
