It does absolutely nothing.
I use it daily, I feel a slight sting in some areas during use, and having already gone through a week of daily use (as the instructions say and not once or twice a week), I have not seen any improvement.
I am puzzled by the rave reviews

I like the scent. However, I have been using it every night for a while now and I don't see any difference. Maybe my skin is quite tolerant and needs a higher percentage of acids, I can't explain it otherwise. Also, it has a cumbersome packaging that spills a lot of product, especially for those who don't want to waste it on cotton and pour it directly into their palms like I do.

Having been in a routine with exfoliating serums, with acids, etc. for 5 months now, I have already seen a difference in my skin so I can't say if the change from this toner is dramatic. I generally have oily skin and have had acne for many years. It doesn't sting on the face except for the first time if I remember correctly and generally keeps it without oiliness. The exfoliation is visible when I apply moisturizer afterwards and massage, and the skin peels off leaving behind a cleaner and brighter skin. As for acne, I think the pimples dry a little faster but it's not that they don't come out. Especially if bought on sale, it is a very honest choice. It has a large quantity for its price!

I definitely use it for a month morning and evening and it has done a good job for what it is. Don't expect retinol results. Definitely my skin looks better than before and its texture is smoother than before. I consider it a very good alternative if you don't want to start retinol. Even older acne marks have changed and are not so intense anymore.

Very good product. I saw results from the first week of application. My skin is more radiant. I will definitely buy it again

I never believed that such an affordable range bottle would do such a good job!!! I bought it out of curiosity and only because it was on sale for half the price and I saved myself!!!!!!! The result is truly visible from the very first use. My skin whitened!! It also calms down the pimples a lot!!! It's worth it!!!

It does the job just fine and we got it on sale for 3.5 euros if I remember correctly, so we bought 4 of them together.

You wash your face, then you use this on a dry face, once you're done you need a cream because otherwise your skin will dry out. We don't know if it cleans well, we just bought it because it has glycolic acid. In the past, we have used mild chemical peels that did a better job, but for everyday use, I think this is just fine.

We will buy it again if the price drops significantly. At the current price of 6 euros, I don't know if I would choose it.

I was very skeptical about buying this toner, due to my dry and very sensitive skin. However, it is wonderful! I am 45, with very "tired" and dull skin. I have been using it for a few days and from the first few times, my skin brightened and glowed. And most importantly: without any irritation at all!! Not a single redness, nothing! It seemed unbelievable to find a peeling toner that would work without causing irritation. And yet, it exists! Needless to say, I will buy it again.

The automatic questions of Skroutz are invalid!! The product is an exfoliating toner and not makeup remover. It does not go into the eyes. It requires attention in usage and the products you will combine it with. It is used twice a week, at night after makeup removal and before moisturizer. I will definitely buy it again once it runs out

Ideal percentage of 5% for those who want to start glycolic acid. Use every three days in my evening routine and already after a month, the skin has changed for the better. I recommend it.

It is one of the best products I have ever put on my face!!!! I will buy it again and again! It's magical! It instantly brightens the face, the next morning it is radiant and soft. It removes any pimple in half the time at least. I have never seen more immediate results from a product. No irritation and I use it every night. It smells like retinol serum, freshness.

Nice toner, gentle exfoliation. It didn't cause any irritation and removes all makeup residue after cleansing.

I have been searching for a good chemical exfoliant for years. The first impressions were very good. Satisfactory skin smoothing, helps (in combination with other products of course) to address pimples & imperfections and gives a glow to the skin. Besides the occasional slight tingling, it hasn't caused any irritation. I alternate using it (one day this one & the next day the other) with the corresponding Revitalift Glycolic Acid Gel cleanser.

Very good, I have been using it for a short time but I have noticed a reduction in pimples. I will continue to use it and would buy it again.

My 15-year-old daughter, who has acne, dry skin, and many black spots, did an excellent job with this product, without any irritation or dryness when used daily in the morning and evening. I noticed that besides being exfoliating, it is also quite moisturizing. As for myself, a 44-year-old with oily skin, I use it as a simple toner, it goes well with everything, and after a few days, it enhances the radiance of the skin. I have bought it three times and I continue to use it.

With just a few applications, the appearance of my skin has already changed. It did not cause any irritation, even though I generally have sensitive skin with tendencies for acne.

Much better than I expected. It provides a nice gentle exfoliation and with regular use, you can see a glow on the face. Personally, I don't use it every day. Another plus is that it helps to make pimples disappear faster.

Fantastic toner has immediate results of cleanliness and brightness of the face, and glycolic acid is very effective on most skin types. In my case, it hadn't worked well as an ingredient until now, but as soon as I tried this product, even though I was hesitant, I immediately saw the difference. Of course, be careful with the ingredients we use, it would be good not to use it every day, morning and night, as it may irritate some skin types. And of course, sunscreen in the morning!

Excellent product. I have been using it for the past 2 months and I have seen a significant difference in my face. Smooth, soft, reduced discoloration and marks from previous pimples, and best of all.. I don't have new ones(!) I have already bought it three times!!!

Very good product, gives shine in 3 days of use, easily combines with the rest of the facial care

I have been using it for a month and I am very satisfied with the result. The first time I used it, it left my skin incredibly smooth. After a month of use, my skin is brighter and there is an improvement in texture. It irritated me slightly in the first few days. I have oily and resilient skin. Always use sunscreen after using it in the morning.
