I Tried 4 Viral K-Beauty Best Sellers—Here’s What’s Actually Worth Buying

I went into Sukoshi at Bellevue Square and asked which skincare products were their best sellers. I purchased all four and put them to the dermatologist test: • Medicube Triple Collagen Serum • Medicube Collagen Jelly Cream • SKIN1004 Hyalu-Cica Water-Fit Sun Serum SPF 50 • Round Lab Birch Juice Moisturizing UVLock Sunscreen SPF 45 Do topical collagen products actually rebuild collagen—or do they mainly provide hydration and temporary plumping? And which of these viral Korean sunscreens would I choose? I tested the textures, reviewed the ingredient lists and ranked all four products. Remember that U.S. sunscreen formulas may use different UV filters from the Korean and international versions you’ve seen online. This video is not sponsored. I purchased all four products myself.
