When I first heard about CosRx’s Triple C Lightning Liquid back in April, it was because it was already sold out. An hour after it launched. It then had a 10,000-person wait list. Why? Because the high-potency serum is magically both effective and gentle; it delivers big results, promising to “Hydrate & Illuminate.”

TCLL is pure 20.5% Vitamin C, which is one of the most powerful ingredients for brightening and tightening skin, and reducing dark spots. The antioxidant helps fight inflammation and promotes collagen production.

At $27 and double the size, TCLL is more affordable than my Glossier ‘Super Glow,’ and the watery consistency is the same. I like to alternate between the two, just to keep my skin on its toes, but if you’re looking for a powerful and affordable serum, this is my number one recommendation.

Have a great weekend!
