Please recommend an effective treatment for freckles and blemishes for the summer.

Even though I try my best to carefully select and apply sunscreen, I can feel my melasma spreading noticeably and darkening whenever the weather gets warmer or I spend even a little more time outdoors. I am very stressed because every time I look in the mirror, my face looks dull and patchy overall. Even when I try using whitening products, I find that there is a limit to how much home care alone can lighten deep-seated melasma or dark blemishes that have already surfaced.

I hesitated a bit about visiting a clinic because I heard that laser treatments in the summer can irritate the skin or worsen pigmentation. However, I have heard that there are many pigmentation treatments available safely even during the summer months these days, so I plan to seek help from a specialist.
