Amazing stuff, and very affordable
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!!!

Turns out I can use glactomyces!
So, I’ve tried several glactomyces/fermented products because of all the many skin benefits it claims and all of them broke me out, until I found Cos de Baha! I’m not sure if it’s the simple formulation of this serum, but it works so well and it doesn’t break me out! Finally!!! I have wanted this ingredient in my skincare for years and I can finally use it! The serum is moisturizing but not sticky, scentless and seems to help my other skincare absorb better. Also, my skin seems brighter and more supple. I pair this with the Cos de baha azeleic acid twice daily and my skin looks amazing! I have acne prone, combo skin and I’m 38 years old for reference.

Bad reaction
It made me break out really badly. Lots of small red bumps on my cheeks and neck.

The niacinamide broke me out.
I'd just used up my Whamisa flower essence, and was looking for something just as hydrating with the added bonus of some skin brightening. This serum is super hydrating, and light weight. I like the texture more than Whamisa, which was a favorite. I've applied it before bed, my sensitive skin will let me know if it's a keeper by morning. So far so good. Update 8/19/19 Sadly my skin began to react to the niacinamide in the product with redness, and small bumps on my cheeks. My moisture balance is so off now. I've got to nurse my skin back to health. Back to Whamisa deep flowers toner for recovery.

Doesn't reduce blackheads but moisturizes well and adds a radiant glow
I used this every day for over a month. Though it always kept my dry skin soft and moisturized (I even used this instead of a moisturizer), I did not notice much reduction in any of my blackheads which is mainly what I purchased it for. Fortunately the serum does add a long lasting super glow to your face! You will definitely look radiant afterwards. Therefore I would recommend it if you do not have blackheads.

Be-gone Blackheads-HELLO BRIGHT SKIN!
Amazing-great price. Using it religiously since I received it, and have definitely noticed a reduction in the blackheads along my nose and on either side just under my lip (this daily mask wearing for long hours has created some serious open comedones AKA black heads)! Also seeing the brightening effect over my entire face neck and chest! Definitely an excellent purchase :-) Thanks to Penny Smith-I've found a 'keeper product's in my arsenal 🙌

Awesome.. Not a paid reviewer or get an item free
Wonderful product, it makes me feel renewed, brand new and can instantly see a difference in my face when I wear so I feel to wear it everyday but I dont. I saw a reviewer claimed that it caused a fungus on her face due to the fermentation. I hope this does not happen to me because I love it so much. I wear it to sleep and to work when I can, very awesome product and will check out their other lines.

HYDRATES AND MAKES SKIN EVEN TONE
Working slowly but you will get results. It will hydrate your skin and takes time to absorb into skin.

Hydratant et non gras
J'ai découvert les propriétés très hydratantes des galactomyces. C'est bluffant ! Associées à la vitamine B, ce sérum est une pépite pour une hydratation en profondeur sans effet gras ! Il donne une nouvelle santé à la peau ! Je suis conquise!

Great formula!
I really liked this product. I found the formula really pleasant and effective. It left my skin healthy looking and hydrated. I was very impressed. Pity it is out of stock for months now. I would repurchase immediately.
