Would it be okay to consult about wrinkle Botox along with melasma and blemish management?

I am looking into pigmentation treatments to manage the melasma and blemishes that appeared after pregnancy, but lately I have also become concerned about the wrinkles that appear when I make facial expressions. Since I believe I need a consultation to determine the exact location and depth, I am wondering if I can discuss both my pigmentation and wrinkle concerns at the same time. I would also like to know if wrinkle Botox is evaluated based on wrinkles that form when making facial expressions, or if a different approach is considered for lines that are visible even when at rest. Is it okay to start laser treatment for melasma or blemishes close to the time I receive wrinkle Botox? If possible, I would like to know if they are performed on the same day or if there is a gap to monitor the skin's reaction. Please also let me know what items are checked first and how the order of procedures is determined when consulting about both concerns simultaneously, as well as what precautions I should take during the dry winter season, besides moisturizing and sun protection.
