Famed for their nourishing skincare products packed with efficacious actives and natural botanicals, both Ole Henriksen and Sunday Riley are more than worthy of occupying some shelf space in your bathroom.
Come with us as we compare their best-selling Vitamin C serums side-by-side to help you decide which is best for you and your skincare routine. Enjoy!
Ole Henriksen vs Sunday Riley Vitamin C
Vitamin C is by far the most popular vitamin in skincare, and rightfully so. Regular use of vitamin C helps your skin produce collagen, heal wounds, reverse sun damage, brighten your complexion, prevent aging, and improve overall skin tone. Experts recommend that even the simplest of skincare routines should include vitamin C because it also makes your SPF more effective.
For this match up, we'll be comparing Ole Henriksen's Truth Serum vs Sunday Riley's C.E.O. 15% Vitamin C Brightening Serum.
Worth noting upfront is the fact that both serums not only contain Vitamin C, but also contain another goodie in the form of Vitamin E which helps to protect skin cells from damage and reduces inflammation. That's about as far as the similarities between the two go, though.
The Sunday Riley CEO Vitamin C Serum contains one of the most effective forms of Vitamin C at the most effective concentration: 15% THD Ascorbate. Both highly stable and oil-soluble, it rapidly absorbs into the skin for visible anti-aging benefits.
The Ole Henriksen Truth Serum, on the other hand, contains a weaker form of Vitamin C at a much weaker concentration: a combo of 1.5% Sodium Ascorbyl Phosphate and Calcium Ascorbate. While in theory this makes it "much more stable", the effects are far less potent than that of Sunday Riley's.
In an attempt to make up for the lacklustre concentration of vitamin C, the Truth Serum also contains Hydrolyzed Collagen which helps improve the skin's elasticity. Meanwhile, Sunday Riley's formula includes Phytosterols which naturally increase the skin's production of collagen, while also helping to reduce the look of redness due to skin sensitivity.
The C.E.O. serum only gets more impressive when you discover it also contains Glycolic Acid, which not only refines skin texture, but also keeps the pH of the final product at the perfect level for maximum Vitamin C effectiveness.
Maybe we got a bit carried away on the Sunday Riley hype train, but the difference truly is night and day. However, one massive plus in favor of Ole Henriksen's Truth Serum is the fact that the lower concentration makes it perfect for those that are new to Vitamin C serums. Take it from us: getting chemical burns is NOT fun, and your skin needs time to build up a tolerance to the potency of Vitamin C.
For veteran Vitamin C users, seriously look no further than the Sunday Riley C.E.O. 15% Vitamin C Serum. It delivers the most precisely optimal dosage of Vitamin C that you can possibly find, and you won't find one better.
For those looking for their first foray into the world of Vitamin C serums, the Ole Henriksen Truth Serum is an excellent start due to it being a lot weaker, allowing your skin to grow accustomed to the potency of Vitamin C.
