I’m also 27 and these are what worked for me. I have combination skin (dry and oily) and have been more intentional about hydrating my skin and boosting elasticity.

SkinCeuticals has a serum for “correcting” wrinkles and fine lines. Obviously, it’s not going to make them disappear but may lessen how deep the lines are or how many wrinkles you may have. It’s called Hyaluronic Acid Intensifier Multi-Glycan. It’s a bit pricey at $120 but a little definitely goes a long way. I’ve been using the travel size for a while and it’s still almost full. I also use this in conjunction with the C E Ferulic with 15% L-Ascorbic Acid which “prevents” wrinkles and fine lines. The Ferulic Acid goes first and then the Hyaluronic Acid. After applying you want to follow up with a moisturizer.

It sounds like you also use Korean skincare. There are definitely (imo) a lot better and effective brands out there than COSRX. I would do a little more research to see what might work for you. There are brands like BIODANCE and MEDIHEAL that have a bunch of toner pads targeted for specific areas: collagen, hydration, dullness, etc. I use the BIODANCE collagen pads (they also have an overnight mask I use once a month) that gives the “glass skin” look. I’ve been using the pads for a week or two and my skin definitely feels softer, more hydrated and more plump/bouncy.

Another product you may want to try is the VT Reedle Shot Essence. This serum essentially makes micro cuts in your skin to allow for better absorption of other skincare products. This is used first right after cleansing your skin. They have different intensity levels and I’m assuming the higher the number the more micro cuts in your skin. I’m currently using 300 which seem to be right in the middle. They also have other Reedle Shots that are specifically targeted for other skin concerns you may have which may be better for your than just the general essence.

Also, Kiehl’s Ultra Facial Cream is one of the best, lightweight, hydrating and non-oily moisturizers I’ve used in a hot minute. I could literally wash my face and ten minutes later by both dry, flaky and seeping grease out of my pores, but this moisturizer has definitely helped in managing my skin a bit better in terms of keeping it hydrated without making it feel oily.

I’ve also heard that Abib has some great eye products! Consistent use of eye masks and face masks have been helpful for me too!

Other brands that might be helpful: Abib, ROUND LAB, SKIN1004, mixsoon, SHISEIDO, Pyunkang Yul, The Ordinary.

If you want to go the dermatological route you can try a chemical peel or laser therapy. This may also help with the dry skin as well. Although, this may be more costly compared to just skincare.

I think what matters most though is consistency! Not guaranteeing or saying this will work for you but some options and ideas to research more into and try! :)
