I could only use this for 3 months before it oxidized. Although it's been mentioned in their YouTube channel that it can be used even when it turns mild yellow, I've noticed that it's effectiveness has gone down to almost nothing. It has a high percentage of Ascorbic Acid without any stabilizing ingredient, hence the oxidization makes sense! It felt extremely tingly and warm in the beginning but it went away after a few days. This could potentially be irritating to those with sensitive skin. I still have half the product left and I am still using it in combination with a sunscreen. Overall, it's a decent Vitamin C serum but needs to be handled with care as it oxidizes very quickly.

The ingredient list here is not full, whoever add this product here did not do the work full heartedly. This product contains castor oil and polysorbate and high amount of alcohol. My mistake to trust this and bought it, then i saw the ingredient on the packaging and i dont think i can use it. A waste of money. Should not refer to this site only from now on.

I love this product, it helps a lot with the hyperpigmentation. Before you use it, you have to do the patch test to see if you're allergic to this product.

It's kinda sticky, but it spreads good on the skin. My oily skin takes some time before absorb it totally, but on combinated/dry skin could go faster. If it's your first time with this type of products, you could feel some tickles in your face, but it's normal meanwhile it won't burn/give redness/give heat to you.

I use it during night and I see that the skin tone is better, my face feels tight (but not in a painful way) and illuminated. The scent is like citrics, really delicious! I recommend it!

Before I bought this I heard so much about it. It really was a product everybody seemed to love, and really sold a lot. I decided to buy it to try and even my skin tone.

Used to fade acne scars and help with hyperpigmentation, even the skin tone and firming the skin

This product comes in a dark glass bottle with a dropper. The bottle is dark due to risk of oxidization. I feel that the best way to store it is in the box in the refrigerator and it will keep it from oxidizing too fast. The temperature and the lack of light will make it last a little bit longer.

Directly after applying it the skin will feel a little bit sticky, this goes away when you apply the rest of your products over it.
