What are the best skincare products to use after beauty treatments?

Hi girls! I'm Shahd from the UAE and I'm planning a trip to Korea next month for some beauty treatments. Honestly, I'm confused about what skincare products to pack. I've read about the importance of proper aftercare, and I'm worried about bringing things that aren't suitable for my skin or won't be effective.

I wanted to ask, what products have you recommended? For example, cooling products and cold masks, silicone sheets for scars, or soothing gels? Do I really need to bring these from home, or can I find them in Korea? And how much is it worth investing in good quality products?

Anyone who has tried beauty treatments, please share your advice! I don't want to skimp on aftercare because I want the results to be perfect 💙
