At thirty-five, you're at a good age to consider botox if you're seeing fine lines that bother you. However, prevention is also important, so you might want to combine botox with a solid skincare routine including sunscreen and retinol. Some people prefer to start with skincare and other treatments like laser or microneedling before moving to botox, while others jump straight to botox for prevention. It really depends on your goals, budget, and comfort level. A consultation with a professional can help you decide the best path forward.
