Geologie vs SkinCeuticals: Which is the superior Vitamin C Serum?

The hunt for the perfect anti-aging vitamin C serum can feel impossible when there are so many products to choose from. To help you decide on your next holy grail brightening serum, I’m comparing two of the best vitamin C serums out there: Geologie Vitamin C+E Ferulic Serum and SkinCeuticals C E Ferulic. But with one serum being three times more expensive than the other, I wanted to know whether a higher price tag always means better quality…

If you want a serum that soothes and strengthens the skin barrier… Geologie

While both brands contain 0.5% ferulic acid, anti-aging vitamin C, and vitamin E, Geologie’s formula also boasts a few extra skin-loving and antioxidant ingredients. The serum contains aloe vera, which is a great calming ingredient for sensitive skin, making it ideal for all skin types and everyday use (even during winter!). It also contains the powerhouse ingredient niacinamide, which helps strengthen the skin barrier, reduce the appearance of enlarged pores, and control excess oil. I adore a serum that can do it all! My skin is loving the Geologie Vitamin C+E Ferulic Serum.

If you love beautiful and smart packaging… Geologie

I’ve got to give pretty packaging to Geologie. The serum’s modern grey packaging with minimal and easy-to-read text is sleeker. Did someone say #SkincareShelfie? Geologie’s packaging doesn’t look clinical or boring either and is very gender-neutral. Not only is the packaging beautiful but it’s opaque and airless, which means air and light are prevented from degrading the vitamin C. The result is that Geologie has a much longer shelf life and it won’t lose its efficacy. I love the pump dispenser too, as it’s so easy to use.

If you value product history… SkinCeuticals

It wouldn’t be fair to not credit SkinCeuticals for creating the original vitamin C + ferulic acid serum. The brand’s patented formula paved the way for other fantastic (and more affordable) vitamin C + ferulic acid serums to follow. Since SkinCeuticals first released its serum, skincare has come a long way, with more and more innovative products cropping up - like Geologie’s serum. But, I still have SkinCeuticals to thank for the incredible skin duo of ferulic acid and vitamin C.

If you’re looking for a serum that won’t break the bank… Geologie

Ultimately, you don’t need to spend upwards of $150 for a serum that delivers seriously amazing results. Geologie Vitamin C+E Ferulic Serum is a third of the price of SkinCeuticals C E Ferulic and delivers just as good results. Furthermore, Skinceuticals uses L-ascorbic acid which is very unstable, while Geologie uses Ethyl Ascorbic Acid which is the most stable form of vitamin C. So, it’s a no-brainer to pick up the Geologie serum at $48 for 30ml, rather than the SkinCeuticals at a pricey $169 for 30ml!

The verdict? Geologie wins

Geologie Vitamin C+E Ferulic Serum is the ultimate winner! It’s more affordable, has a great ingredients list, and looks fantastic on my skincare shelf. I love that the gel serum is lightweight absorbs quickly, and never feels sticky or greasy on my oily skin. My only complaint is that I’m seriously having to refrain from applying this every hour, as I’m addicted to the glow!
