I’ve tried many Vitamin C serums, but the Dr. Althea Vitamin C Boosting Serum is a standout. What makes this different is the 20% Vita Boosting Complex combined with Tranexamic Acid and Alpha-Arbutin. It targets dark spots and uneven tone from multiple angles without the 'sting' associated with pure ascorbic acid. The texture is watery and lightweight, absorbing almost instantly without any stickiness. I also love that it contains 8 types of Hyaluronic Acid, so it keeps my skin hydrated throughout the day. If you have sensitive skin but want the brightening benefits of Vitamin C, this is the one to get Read more

I’ve never written a product review before, but I felt like I had to share my experience with this one. This is by far the best vitamin C serum I’ve ever tried. My main goal was to make my freckles less noticeable, since I personally prefer a more even skin tone, and this serum has truly helped brighten my skin and even it out. My skin honestly hasn’t looked this good in a long time, and I’m pretty confident this product is a big reason why. That said, I’ve also been putting a lot of effort into my skincare overall like using face masks regularly and sticking to a solid routine, so I know other products have helped too. Still, the Dr. Althea Vitamin C Serum has easily become one of my favorite steps in my routine. 10/10, would definitely recommend! Read more

I’ve been using the Dr. Althea Vitamin C Boosting Serum every day, and it has quickly become one of my favorite products. 💫The texture is slightly thick, but it absorbs very quickly and doesn’t leave any greasy feeling — even oily skin types can use it perfectly.✨ It doesn’t irritate my skin like other vitamin C serums and gives my face a natural, healthy glow. It also helps fade dark spots and even out the skin tone over time. 🌸My skin looks smoother, brighter, and more radiant every day. Perfect for anyone looking for an effective yet gentle daily vitamin C serum.🌷 Read more

I’ve used this for a while after seeing the high reviews. The formula is quite thick, so it can be difficult to layer and requires waiting between steps. It does deliver on its promise with a noticeably strong vitamin C effect, but I’m unsure if I’ll repurchase as it isn’t the most convenient fit within the rest of my regimen. Read more

Non greasy feel. Does not feel thick. Absorbs very easily once applied. No odor with application. Applicator is easy to use. Layers under other skincare easily. Does not provide much hydration given it's a Vit C cream but it helps with brightness slightly. Easy to use other products on top. Read more

I’ve tried several Dr. Althea products and loved all of them, and this Vitamin C Booster Serum is no exception. I have sensitive skin and it doesn’t irritate me at all. Every time I use it, my skin looks brighter, smoother, and it hasn’t caused any breakouts. It has also helped fade a few dark spots I had. A gentle, effective serum that’s perfect for sensitive skin.
