Hi ladies, I think that Korea is having a bit of a moment because their cosmetics industry is really highly developed. And that translates to novel, innovative high-tech stuff at high street prices that anybody can afford! Lots of the Korean stuff feels space age compared to my La Roche Posay! Getting optimally hydrated without spots is not always easy, but Koreans definitely know how to do it.
If you want to experiment a bit with Korean stuff, sheet masks are the easiest way to start. Just order one or two on eBay. Pick a neutral one like hyalurone, collagen, rice or pearl, something nice cooling and hydrating like aloe or green tea, or just about any berry or plant that appeals to you. If you want something more exotic, there is bee venom, snake venom, shark or placenta
Some are scented, others are not, and your first foray into this should not cost more than a few quid. If you like them, you can buy them in bulk for less. For me, the result is visibly prettier, more hydrated and glowier skin.
If you don't like face masks, try a sleeping mask (I gave a few links earlier in this thread). Clean your face, moisturize it (optional), and then add a sleeping mask. It feels just like any regular moisturizer, but it plumps up your skin overnight. You wash it off in the morning. My skin feels incredibly silky and soothed afterward...
Or if you want just a cream that is a bit different, try the snail cream lots of people here are loving.
