Beauty of Joseon vs COSRX

I remember that BOJ got into lawsuit for their ginseng products, however I didn't dive deeper to see which particular products. With that in mind, I would choose the cosrx instead.

Definitely the COSRX Snail 96 Mucin Power essence! It's extremely gentle and I find it's great for repairing and healing skin damage.

Both are gentle products but won't really address dark spots or hyperpigmentation. These are more for boosting hydration. Serums with brightening ingredients would work better as they are more potent. But if you're looking for a daily lightweight toner/essence, the BOJ might be better due to it's light, water-like texture compared to Cosrx's thicker, slimy, more viscous texture. BOJ would be better for layering multiple times as it's not very hydrating with just one layer, Cosrx is great for when you want quick hydration with just one layer. I think it comes down to the consistency/texture and your personal preference, besides the ingredients.

I would recommend these for soothing and brightening, they will help with dark spots and texture.

Snail mucin + peptide sounds cool if youre thinking of trying the cosrx one, but with peptides as a bonus!
