C-Firma Day Serum

I was given this as a sample. Texture is slightly thicker than the normal watery vitamin c serums I've used in pas. Its orange in colour and as previous poster stated, it would be difficult to assess when if its oxidised,, however its bottle which is opaque so I think its efficacy would remain safe.
I didn't experience any side effects,but the cost is prohibitive to me. The …Read more

I am in my 30s, and still suffer from oily, acne-prone skin. I wanted to include some better anti-aging things in my routine since I am getting older and want to stay as youthful looking as possible :) I have tried a few …Read more

I suffer from acne prone skin which started in my early 20’s. Let me tell you, since then I’ve been on the search for the right product. I ended up using many products that Instead dried out my skin and destroyed my skin barrier. When I first started using this, I gave it about two weeks and decided it wasn’t for me. Mind you I did break out so I was very upset. I’m not sure if I was purging or …Read more

I love this serum. I use it every morning before applying my tinted moisturizer. Doesn't seem to make my skin more greasy, hasn't broken me out. I keep it in the refrigerator as recommended. It has a weird taste if you accidentally apply to your lips but it's not supposed to go on your lips anyway, so it's fine. Will continue to repurchase.

PSA- when I used this my whole face went red and it gave me HORRIBLE breakouts all over!!! My brother was calling my pizza face after using this product! Plz do not waste you’re money on this you will be paying for irration! This also has a very strange smell!

This was the first vitamin C serum I tried so admittedly I only have one other to compare it to (Timeless). What I loved about this was the potency and the packaging. The pump is very air tight and ensures the product lasts longer and I think the formulation is good compared to a lot of Vit C containing products that seem unstable.

What I disliked are that the serum itself does not …Read more

The two stars are just for the ingredients, that basically are good. However, for a serum of this high price, i would expect a more elegant texture (when it dries to skin is tacky not matte, better absorption (it takes almost five min to sink into skin) lighter irritation (i know the percentage is high and the skin will occur irritation but still) and of course to be oil free, also the colour of …Read more

Like with all L - Ascorbic Acid type products, D.E. leaves a sticky residue feel afterwards. And with all L - Ascorbic products, I will rinse off after a few hours. I just can't handle that tacky feeling. I purchased the mini combo C Firma + B Hydra serum. I realize the B Hydra is suppose to be used with the C Firma, but like it better on it's own. I'm not completely sold on the …Read more

I didn't want to love this, but I do...I am on my 3rd bottle.

After cleansing, I mix this with B Hydra (can't live without this). The 2 together give my combo skin the perfect amount of moisture for my morning skin. This combo gives me super glowy, soft skin. I apply Marula oil to dry area, around my eyes, neck, around my mouth, and I'm ready for sunscreen and the rest …Read more

Terrible terrible. It stings and after a few hours my skin is a terrible mess. Oily and greasy.... Not worth the hype
