Opt for 1ml lip fillers, particularly if you’re a beginner. Even if you’ve had lip fillers before, we recommend sticking to 1ml. Yes, a certified and experienced practitioner may recommend the 2ml option for experienced users. Even then, such a recommendation is reserved for well-evaluated contexts.Based on our long-term experience, you should start conservatively with 1ml. Then, allow 3-6 weeks for the fillers to settle as you assess the experience and results.
