    A good alternative to l-ascorbic acid based Vitamin-C serums
  

*by C***R on Reviewed in the United States on June 2, 2015*

Good product, arrived quickly. It is based on Magnesium Ascorbyl Phospate (MAP), a more stable vit C ester, whereas most Vit-C serums are based on L-ascorbic acid. Having used C-serums based on L-ascorbic acid I can say that L-AA based serums give you more glow and instant results but this worked pretty well too. I I'm using a BHA (salycilic acid) product morning and night and an AHA (glycolic acid) nightly and was frustrated with the requisite wait times in-between actives. L-AA based serums should be applied to near-bare skin and you are supposed to wait before you apply any other active over it . . . who has the time for that!? Juggling all the proper pH values across skin products can be tricky too! The Celsignal serum has a pH of around 5-5.5, about the pH of healthy skin. While I did have to wait a little for my BHA (pH 3.7) before applying the Celsignal I didn't need to wait for anything else; I could apply the Celsignal and immediately slap on my lotion and sunscreen. The beauty of MAP based serums is that you can apply things over it so quickly, it definitely cut down time on my routine. I suffered some nasty post-inflammatory hyperpigmentation (PIH) in between bottles of this so I'm going to switch over to NuFountain's L-AA + Ferulic serum for a little bit because I think L-AA gives quicker, more potent results but that isn't a knock against MAP, you just have to be more mindful of its subtler effect. If you are using a Vit-C serum for primarily preventative purposes and not to lighten PIH I would recommend this (MAP) instead because its easier to work with; if you have a lot of PIH start with L-AA and then switch over to MAP. The only bad thing to say about it is that I dislike the level of Panthenol in the ingredients, I don't like the finish/texture. Otherwise: Good.

    Quality ingredients yield measurable results
  

*by L***Y on Reviewed in the United States on July 14, 2015*

I think that this is a decently made product. The ingredients are quality, and they're present in concentrations that will actually do something. According to a customer service rep whom I emailed, the niacinamide is present in 5%; research shows that it is effective at concentrations between 1-5%. This is awesome because niacinamide stimulates your skin's production of ceramides, natural lipids that are a part of your skin's protective barrier. They also use Magnesium Ascorbyl Palmitate, a form of vitamin C that has been shown to be effective in anti-aging in concentrations above 5%. Lastly, Hyaluronic acid is one of my favorite ingredients because it pulls moisture from deeper layers of skin up to the surface.After using this serum for a couple months, the dark post-acne spots on my face have faded considerably, though I do attribute some of that progress to cheap ole' time!  The serum is a bit tacky after application, which put me off at first because I don't like the feeling of leftover product on my skin. However, I emailed their customer service department and they said--in a very detailed, thoughtful response--that I can rinse off the product once it's dry without sacrificing any efficacy.  Apparently the vitamin C absorbs into the skin within seconds and the niacinamide absorbs within a minute, so there's no need to keep it on longer than that.Note that when the serum arrives it should be a very light, translucent yellow. As it ages, that color will darken due to oxidation. I recommend using up all the product within three months because it will lose efficacy over time.

    They discontinued their best serum!
  

*by S***E on Reviewed in the United States on October 4, 2013*

I loved CelSignal and I'm so said that it's discontinued. My skin doesn't react well with L-ascorbic Acid, so the CelSignal was the perfect choice for me and now that I need a new bottle, it's gone. Very, very sad.UPDATE: It's back! Just found out, already ordered a bottle, so happy that NuFountain listened to their customers!
