Is soothing care essential after laser treatment? I wonder what LDM is like lol

I'm booking an appointment at a dermatology clinic soon to get a full laser treatment for melasma and blemishes! However, since my skin is extremely dry, thin, and sensitive, I'm a little worried that my face might break out or get too red after the laser treatment. I've noticed that many people apply ampoules, sheet masks, or get additional soothing care after the procedure. If I combine the laser treatment with a soothing treatment like LDM Waterdrop Lifting, does it definitely help reduce redness faster and aid in skin recovery? Please share some real-life tips from those who have tried it to see if the post-treatment soothing care is worth the money compared to just getting the laser alone, or if it helps protect the skin barrier.
