Nowadays, micro-contouring is so popular and respected by everyone, many people would like to be able to do the injection program and laser program together, to get the best of both worlds, but then the question arises, in the end, the two programs can not be done at the same time, there will be an impact on it? We have divided the injectable program into wrinkle injections and filler injections to answer the question. First of all, can I have laser cosmetic treatment immediately after face slimming/wrinkle removal injection? Face slimming and wrinkle reduction injections are essentially botulinum toxin injections (BOTOX, HENRY). The injection volume, level and diffusion range of Botox need to be precise so that the effect will also be more perfect. Therefore, it is not recommended to carry out laser cosmetic immediately after face slimming and wrinkle removal injections, and it is generally recommended to carry out laser cosmetic after 2 weeks after the injection. Can I have laser cosmetic treatment after filler (hyaluronic acid) injection? Hyaluronic acid injections are mainly in the subcutaneous, deep dermis, or even deeper levels, so from this point of view, most laser cosmetic (such as photorejuvenation) treatments have no effect on hyaluronic acid. However, such as radio frequency, ultrasonic knife treatment, due to the deeper role of energy, generally recommended to avoid this type of treatment program within 2 months. Then the other way around, can you directly carry out injection projects after laser projects? Can I inject hyaluronic acid immediately after laser cosmetic treatment? Generally as long as the treatment is not scabbed, no oozing, after the cold compress can be injected, but to consider the laser cosmetic interval and hyaluronic acid stabilization time, which generally need to listen to the professional doctor’s advice. Can I have face slimming/wrinkle reduction injections after laser cosmetic treatment? In general, after laser cosmetic treatment (e.g. photon, radiofrequency), it is possible to have injections after applying cold compresses to stabilize the epidermal temperature. However, some lasers will form scabs (e.g. CO2 laser, plasma plasma, pixel laser); some lasers may have oozing (e.g. Q-switched laser for certain pigmentation spots), and these lasers are not suitable for injections after treatment. It is generally recommended to wait for the scabs to fall off before performing cosmetic injections.
