Vitamin C Facial Serum with L-Ascorbic Acid 15% with Vitamin B5 - for Fades Age Spots, Smoothing Fine Lines + Dark Spots, Pore Refining, Resurfacing, 1 Fl Oz (30ml)

I am absolutely blown away by how good Cos De Baja products are. The fact that the products are so very affordable is a huge plus. I have never been able to afford the so-called miracle beauty products with the ridiculous price tags. I just figured, I'm 62 and I just wouldn't worry about getting old and ugly, dry and scalie, bumpy and patchy because I couldn't afford to do anything about it anyway. Then I ran across Cos De Baja's NZ serum...and it was so affordable. I bought it, used it, and was thoroughly amazed at the improvement of my life-long problem skin. So, I decided to add Cos De Baja's VA and GN serums to my face regime after doing some research on them. I have been using NZ for about 2months now, and using VA (vitamin C serum) and GN (galactomyces ferment serum) for about a month. My skin is so wonderful! Finally! I have the best skin of my life. No peeling and flaking for the first time ever. No redness. Dark patches are almost gone. Pores and scars seem to be smaller, thinned down and much less noticable. And soft! I never wear make-up anymore other than a little lip gloss. Blemishes are almost a thing of the past. It is so nice, I cannot say how wonderful it feels not to be ashamed of my bare skin.Anyway, the three major and most important points I want to make about the products, and everyone should take notice of:-The products really work.-The products are very affordable for nearly everyone.-The products are pure, with a minimum of ingredients and no crazy chemicals in them.I only wish so much that I had taken before pictures!!!

I’ve bought several Vitamin C serums made by different companies, and this is the one that works for me. No funky smell, no funny texture, just plain, ACTIVE Vitamin C in L-Ascorbic Acid form. The expiration date is clearly printed on the label (unlike a lot of others), and one small bottle lasts a long time. I use this only once a day, in the morning, along with other actives, all beneath spf 50 sunscreen. This serum has helped lighten my age spots. It took a while, but it works with religious, vigilant use. I have oily skin with dry areas. This helps moisturize the dry areas without breaking out the oily parts. This is the one for me and I will buy again.

Did not like the oily texture very much but I believe it worked well.

Good serum. Not expensive and very moisturizing.

Although this Baha serum gave me a pretty glow, it caused my skin to break out. There were also tiny twitches on my face. It is slightly tacky when you first apply it but it dries somewhat. I was able to apply my powder blush on top of it.Fortunately, I can use Baha's Azelaic serum without any trouble. It worked on milia on my face but not under my eyes. It is a great gentle exfoliant.

Having use it for about 2 week with skin barrier repair as the challenge, it’s working well. The vitamin c hasn’t oxidized like other vitamin c serum, and its non irritating.

This is a genuine review, where I bought the product with my own money.Firstly, I have some hyperpigmentation from tretinoin purges that left my skin barrier extremely damaged. So, I made sure my skin barrier was completely healed before using this slightly irritating vitamin c product.I applied in onto completely dry skin to prevent the product from penetrating too deeply into my skin. So, I either applied on my bare face or after applying toner and letting it dry down. Then I dropped 2-3 drops onto my cheeks and forehead. I noticed a bit of irritation around my nose and mouth, areas with thinner and more sensitive skin, so I avoided it. I tapped it down into my face and let it dry completely to allow the product to do its thing before applying moisturizer. I then applied my serums and lotions, etc. And HOLY COW my skin felt so soft the next morning. I applied again the next day and felt like my skin was slightly irritated. So, I gave my ski around two days to rest before using it again. Now, I am around a couple weeks in and am using nightly without irritation. My skin literally feels so soft, my makeup applies great, and my pigmentation has faded insanely. The product has aloe leaf extract, as well as vitamin b, all of which are great for skin relief and hydration. I will update upon further use, but damn, how did I not know about this product sooner?? For this price, I will be using this for a lifetime. Definitely recommend for those who are scared to use stronger actives such as retinoids, retinols, or azelaic acid!

Great product

He probado una gota en el dorso de la mano y se absorbe bien, no deja grasa, ilumina y rejuvenece la piel. Es lo que esperaba. Pero vuelvo a pedir al fabricante que ponga un precinto en el envaseGracias

Comme le reste de la marque bon serum et bonne formulation attention cependant a utiliser une huile ou un creme après coup pour apaiser la peaux

You can find this product 3x cheaper elsewhere.The product is very good have been using it for weeks and I like it a lot. The only thing again is that I don't understand how they can list this product at this price...

I've been using this serum for a couple of weeks and a little goes a long way. So far so good and it does what it says.It's worth mentioning that vitamin C preparations containing L-ascorbic acid will discolour the skin and nails. The reason it can stain is because vitamin C degrades into erythrulose—the EXACT ingredient you'll find in many self-tanners! Next day, you'll also notice the same smell as if you were using a self-tanner.I'm using a nail buffer to help remove the stains from my nails and for the face, NeedCrystals Microdermabrasion Crystals which I brought here on Amazon.When purchasing a vitamin C serum, look for dark bottles as this one is in. Vitamin C breaks down when exposed to light or air, so dark glass bottles help maintain its efficacy and stability.

It's very costly but you see there's only few brands that make such good formula. I'm surprised that I got my hands on this mighty original serum cuz I'm from a small town in UP huhu thanks to amazon. Anyways It's good for combination and oily skin, It really disappears dark spots, tightens the skin blah blah blah. Be careful when using it for the first time. ♡
