Not all “exosome” serums are built the same. The base formula matters just as much as the headline ingredient. Here’s how I’m breaking down the current edit: Barrier-first hydration (AM / daily use) Look for: • Hyaluronic acid • Glycerin • Panthenol • Light peptides This is where formulas like goop beauty’s exosome hydration serum sit — more supportive, less aggressive. Collagen-focused / elasticity targeting (PM / treatment layer) Look for: • Exosome complexes paired with collagen amino acids • Copper peptides or firming peptides • Niacinamide for tone refinement This is where formulas like medicube’s collagen exosome shot come in — more targeted toward firmness + structure. The takeaway: Exosomes aren’t the trend. They’re the delivery system. What matters is what they’re delivering. LTKBeauty LTKgrwm LTKselfcare
