Vitamin C is one skincare step I keep coming back to when my skin looks a little dull and needs more brightness. I also like having different formulas to choose from, since a strong serum isn’t always what my skin wants that day.

Three options that caught my attention are Paula’s Choice, Sunday Riley, and Stratia.

1. Paula's Choice 25% Vitamin C + Glutathione Clinical Serum

Paula’s Choice 25% Vitamin C + Glutathione Clinical Serum is the one I’d reach for when I want a more concentrated vitamin C formula. The 25% vitamin C content makes it feel like a serious addition to a brightening-focused routine. Glutathione is also included, adding another antioxidant-focused ingredient to the formula. I’d keep the rest of my routine fairly simple around it so the serum can be the main focus.

2. Sunday Riley C.E.O. 15% Vitamin C Brightening Serum

Sunday Riley C.E.O. 15% Vitamin C Brightening Serum has been on my radar because it combines vitamin C with a more polished, luxurious skincare experience. The 15% concentration gives it a noticeable place in a brightening routine without making the product feel overly complicated. I like using a small amount and letting it settle before moving on to moisturizer. It fits especially well into a morning routine when I want my skincare to feel a little more special.

3. Stratia C+C Serum

Stratia C+C Serum takes a simpler approach that I really appreciate. It combines vitamin C with ingredients aimed at supporting the skin, making it an appealing choice for someone who doesn’t want an overloaded routine. The texture also makes it easy to slot between cleansing and moisturizing. I’d choose this one on days when I want vitamin C without making my skincare routine feel too intense.

My choice would depend on the kind of routine I’m building that day. Paula’s Choice stands out for its high vitamin C concentration, Sunday Riley brings a brightening-focused formula with a luxurious feel, and Stratia keeps things more streamlined. I like having options because skincare doesn’t always need to follow the exact same routine every morning.
