Not all Vitamin C serums are created equal, and there are multiple reasons that SkinCeuticals C E Ferulic serum is considered the gold standard. Most people will find no issues with sulfate, however if you find your skin doesn't like sulfates then free feel to avoid them by looking out for the sulfate-free icon on Skincarisma. This is where things start to get interesting. Most of these serums’s color didn’t change a lot except for Timeless. Only CosRx’s formula had gas build up and ballooned again. We also want to note the CosRx formula splattered in a way that almost seemed to not like itself and started to run away from each other.

The third very important ingredient in Dr. Brenner’s vitamin C serum is Ferulic Acid. It’s another antioxidant that has the power to strengthen and boost the influence of other antioxidants. In fact, in this exact formulation, ferulic acid helps vitamin c penetrate the skin better and have a more potent effect. NOTE: I just finished my 3rd bottle and when I was using it 7 days a week on face and chest the bottle lasted me exactly 3 months. We decided to test the top 5 ascorbic acid dupes that we’ve come across from our follower questions, recommendations, and general buzz. These candidates are: CosRX The Vitamin C23 Serum, Paula’s Choice C15 Super Booster, Dr. Brenner’s C Serum, Timeless 20% Vitamin C+E Ferulic Acid Serum, and Maelove’s Glow Maker. INGREDIENTS: Water, Ethoxydiglycol, L-Ascorbic Acid (Vitamin C) 20%, Propylene Glycol, Glycerin, Laureth-23, Tocopherol (Vitamin E) 1%, Sodium Hyaluronate (Hyaluronic Acid ) 1%, Ferulic Acid .5%, Panthenol, Triethanolamine, Phenoxyethanol. Once you’ve made a habit of using the vitamin C serum in the morning, you can also use it in the evening now and again for a nice boost for the skin.Parabens are a large group of preservatives which are used to prevent bacteria growing in cosmetic formulations. As with any other product, you can create your own personal routine that works best for your needs. INCREASES SKIN FIRMNESS AND REDUCES THE APPEARANCE OF LINES AND WRINKLES: Our CE Ferulic serum boosts collagen production in your skin to help even it out. We use 20% of pure L-Ascorbic acid which is pure vitamin C as opposed to other brands who use "sodium ascorbyl phosphate" or "magnesium ascorbyl phosphate" which contain only a fraction of vitamin C. Finally, as an additional comparison, we created our own fresh concoction of CE Ferulic in the lab to compare degradation time. How We Tested These Vitamin C Serums Both Timeless and Paula’s Choice are certified cruelty-free, but I couldn’t find any information on a cruelty free designation regarding Skinceuticals, so I am assuming they are not cruelty-free.

To help counteract this instability and to increase the effectiveness of the serum, SkinCeuticals C E Ferulic ingredients include: Vitamin E helps stabilize and provide a boost in the benefits of ascorbic acid. It helps aid in UV protection but becomes unstable when exposed to UV and air.The Silicone-free label only includes the most common Silicone ingredients that have indentified been reported by individuals that could potentially cause issues. I have never been able to spot any visible improvement whenever I started using any brand of Vitamin C on my skin. If you are concerned about the health safety of parabens, then feel free to avoid them by looking out for the Paraben-Free icon. At the start of 2017 I started using Paula’s Choice Resist C15 and loved it. I went through two bottles and then I became curious how other vitamin C serums would perform (I am guilty of the “grass is always greener” mentality). Timeless reached out to me and asked if I wanted to try their serum, and I immediately said yes. I started using Timeless and about 2.5 weeks later a friend of mine on IG (@refresh_byhilary) sent me the Skinceuticals CE Ferulic serum (her friend mail blew me away with her generosity!). So at that point I started a split-face comparison where I always applied Skinceuticals on one side of my face and Timeless on the other. I did that consistently for 2 months. (Note: It was hard to split my nose up so there was a lot of overlap on my nose–just keep that in mind when evaluating the before and after photos. ALSO, keep in mind Skinceuticals had 2.5 less weeks on my face than Timeless). Overall thoughts on each Timeless Vitamin https://amzn.to/3J9YIfBC Serum
