REALLY small amount, it doesn&#39;t take a month to me and it&#39;s gone :( 
Beside that, I could not name anything that would be a disadvantage.

I&#39;ve been using it for a few months now, and it is a true game changer!! Everyone should know about this product!
The brilliant things about this sungel:
• Nice INCI list, no additional oils, alcohols, it&#39;s pure and good
• No dewy finish, there is an added healthy skin light but it&#39;s not glowing
• Easy to apply, it&#39;s white but when you spread it over your skin, it becomes transparent
• Absorbed fast and easily, it takes me around 2 mins and then it &quot;disappears&quot;, you won&#39;t feel it in your skin, like it&#39;s invisible
• It&#39;s not sticky!
• It is okay to use morning serums before it (I tried it with maximum 3 serums and the spf didn&#39;t move away!)
• Goodie makeup base, primer, easy to put makeup over it
• When you reapply sunscreen, you can make 3 or more layers of it, it won&#39;t fall off or move!
• If you do sports, it&#39;s for you, I ran 10 kms and didn&#39;t sweat it down 
• It hydrates my skin, when I wash it off at the evening, my face is smoother than it was in the morning
• My face is less oily since I use it (the other parts of my routine help too)
• Spf 50, so it&#39;s good for summer too, because of its light, gelly cream, it&#39;s perfect for hot weather too
• You can get from many online store (Dokodemo, EBay, Amazon, Yesstyle), yet make sure, it&#39;s a Japanese product so order it from a Japanese distributor in order to not to get a fake one!
• Very cheap!!

Don&#39;t have any problem with it, my skin loved it! I highly recommend using it!

Everything is good about it! Sooo good for removing my bumps, the redness, acnes. My skin is less oily since I use it. 
After first usage I saw it is more smooth and there are less acnes on it. I use it 3-4x a week in the evenings, I like its texture, it&#39;s basically water-like and very easy to apply on the whole skin - I also use the The Ordinary&#39;s Azelaic suspension for spot treatment only, it is hard to apply to the whole face.
Try to combine with niacinamide, that will be a game changer if you have acne problems!

In the purging period you might get pimples from it, it is normal but still, not very pretty. If you find your pimples where they usually appears, you can know that they are caused by purging. On the other hand, if you start noticing pimples where you do not use to have, you may consider changing this retinol as the formulation and your skin do not like each other.

UPDATE
I am using it for almost a year now, and it is incredible what is makes to my skin. I do not have any wrinkles yet, so I use it as a "prevention", and it really does what it has to. Also must have if you are struggling with acne or stains. 
Do apply spf every day - as usual but with retinol be extra careful - and use this miracle at nights. It's usually considered a more advanced formulation but if you know your skin, it is completely okay to start with this product, 1-2x per week.


Just started using it, its color was surprising, but I loved it, my face didnt turn yellow 😅

I didn&#39;t experienced bad things about this product, if I need to highlight something, I would say purging can occur but after a few weeks of using, skins get used to it

This product had an amazing effect on my skin! I&#39;ve been using it for 2 months now, twice a week . My pores are clean and smaller, my skin is more clean and looks smooth. I use niacinamide with it. Always put it on dry skin in thw evenings aftwe cleansing. I have combined, rather oily skin, it perfectly works for me !

Purging !! Don&#39;t worry if you experience more red stuff on your face, it&#39;s normal. If you&#39;re not allergic to any of the ingredients, keep using it and after about 6 weeks if you still have more and more inconvenience appearing on your face, start looking for another product

Smooth skin right after using it! Use it very carefully, it&#39;s not a leave on product. I use it once a week after cleansing, on dry skin, leave it on 10 mins and then rinse off. I don&#39;t use anything else on that day, toner, lots of moisturising cream and that was it. Results can be seen after a few weeks 
Also, it&#39;s normal that it&#39;s red, don&#39;t worry, you won&#39;t be red after washing your face :)
