I'm planning a trip to Korea next month and want to do a little something for my skin. I haven't decided yet whether to buy skincare products from here or wait until I get to Korea. Has anyone traveled there before? What did you bring that actually helped?

I'm thinking of bringing some cooling patches or masks for post-treatment care because I'm worried about swelling or bruising. I'm also curious if anyone has used silicone sheets for scar care or gel for skin regeneration. I'm not sure if it would be better to prepare these from Thailand, especially since carry-on luggage is limited.

If you've traveled to Korea and have experience with this, please share your recommendations on what products actually work and where to find them. Thank you!
