I have so many blemishes after my vacation. Please tell me how to care for them.

I thought I had applied a really generous amount of sunscreen... but now that I'm back from vacation, I see my skin tone has turned dull overall, and I can see hidden blemishes slowly creeping out. ㅠㅠ

My skin texture is dull like a desert and looks patchy in places, so no matter how much effort I put into my makeup in the morning, it just sits on the surface and looks cakey. Every time I look in the mirror, I am so upset about why my skin tone looks so earthy.

If I want to get treatments at a dermatology clinic for overall skin tone improvement or blemish care, what is the general approach I should take? I am also curious whether I can feel some effect after a one-time session, or if I need to receive treatments regularly for at least a few sessions to see clearer skin.

Please, if you happen to know of any lasers or boosters that were foolproof for making my dull, sun-tanned skin bright and clear again after my vacation, please share them with me! I'm really in a hurry, so I desperately need your advice.
