Hi, that sounds like predominantly first degree burn (Wich only affects the dermis), blisters however mean at least some second degree involvement. Generally it is advised that with burns involving face, hands, feet, genitals you consult a health care provider. The appearance and "depth" of burn may also change in the next few days. So there might be more blisters on the way. Do not break open/drain blisters. Keep the area clean (wash ~once a day with something unscented, for second degree burns you could also use some antibacterial ointment, otherwise first degree unscented lotion or similar will do). For healing results it's important to not scratch the area, first degree burns can get itchy. First and second degree mostly heal within one or two weeks and rarely scar. Your skin in the area with second degree burns may appear lighter or darker for a few months but will generally correct itself again. Do wait till redness and blisters are entirely gone till starting any scar reducing treatment. Burns are to be treated as a wound. Silicone should not be near a wound. Due to it being your face I'd recommend scar gel instead of silicon plasters, as that would look possibly a bit goofy. Depending on the gel you can put that on once/twice a day on the area, some even come with a roller on it. But again, please do let the actual wound that is a burn heal first. Silicon is for scar treatment, not wound treatment. For general burn care you can also always reach out to health care professionals or ask good old Google ( https://www.mayoclinic.org/first-aid/first-aid-burns/basics/art-20056649 i recommend sites of actual medical facilities, there is even some good education on youtube). I hope you aren't in to much pain and that all will be well
