I had the trial size of this Glow Deep Serum. The mini size set contained this Glow Deep, another glow serum that has other types of antioxidants, snail mucin mixed with ginseng, and a green tea calming serum. Out of that set I reordered the two glow serums and likely will reorder the green tea. I use CoxRx snail mucin, which is amazing, so I likely won't order the ginseng and snail mucin though it is a great serum as well.Beauty of Joseon is so calming and so gorgeous on my rosacea prone skin - I have Type 1, which means my cheeks and sometimes my nose will turn red or have some flushing. If my skin barrier is messed up, there could be stinging as well when I use some skincare products.But BOJ calms my skin and this Glow Deep gives my skin a nice glow without being too shiny and is super great for hydration.Alpha arbutin, an antioxidant that is basically Hydroquinone, comes from the bearberry plant, and works as a skin brightener and for post-inflammatory pigmentation, and helps with hydration.It just makes my skin look and feel amazing. I am moving towards having most of my skincare come from BOJ, CosRx, and maybe some Gangnam Glow. These seem to be the ones that make my skin feel hydrated, calm my rosacea redness, give me a glow, help with mature skin, and are inexpensive. And CoxRx and BOJ are not fragranced, though a little essential oil fragrance doesn't seem to bother my skin too bad. But the perfumes will and these brands are not perfumed.
