Facial Serum with Lactic & Glycolic Acid + 3% Aloe Extract Sane Face Serum 3%

The effect of the serum is immediately noticeable: polished and soft skin, delicacy and pleasant scent after application, no dryness or tightness. It pleasantly surprised me that a small amount of serum is enough for the entire face.

After using the serum for about two weeks, my skin's dullness has disappeared, and my complexion has become brighter and more even. There are fewer blackheads and pimples as well. I am currently enjoying the positive effects, so I will continue using it.

I have been using it for a week. It instantly lifts and tightens my eyelids, solving the issue of sagging. It is convenient and pleasant to use, and after a while, I can moisturize it with rose water from Mayur, which works wonders and enhances the effect.

In my opinion, there was no effect whatsoever, but perhaps it's only the case for me.

The delivery, as always, was excellent. Thank you. I applied it immediately, it's not sticky and it tightens the skin. I will give an update.

On my problem skin, it does not cause new breakouts, and that is already a huge plus. I apply it with a thin layer, it absorbs quickly, and what's important, it doesn't feel like a film on the skin, I know that for many, including myself, this is a problem. I want to try the entire skincare line. Maybe someone uses it, please write how you like it.

The serum helped reduce enlarged pores and for the first time, it was able to lighten my pigmentation spots only thanks to this product. My skin has become smoother, more radiant, and has an even tone. I feel a sense of freshness and moisture on my skin.

I am satisfied with the serum, overall my skin condition has improved significantly, it now looks fresh and lifted.

I am very satisfied with the serum. It fits me perfectly. With regular use, my skin stops flaking and becomes silky smooth. I always make sure to moisturize afterwards. However, I deducted a star because the pump broke after the second use in my last bottle :(

The skin did not become better, but it also did not become worse. I have combination skin that is prone to breakouts. After applying the product, there is no feeling of a film and it does not clog pores. Only a small amount of the product is needed for application, but it needs to be spread quickly on the skin as it absorbs instantly. After using it, there is a pleasant feeling of clean and smooth skin. If too much is applied, it will create a film.

I don't see any changes.

I really liked it! It's really cool.

Decent serum.

The serum is quite decent for its price. If we analyze the composition, glycerin and aloe vera extract are the first ingredients, which is pleasing because these products soften the skin. However, due to the acids in the composition, the moisturizing effect is slightly insufficient. It dries out pimples and reduces the visibility of pigmented spots. It works effectively for about 90% of users.

The serum caused a breakout, and after that, some strange white pimples appeared all over my face. I have never experienced anything like this before. Even during my teenage years, I never had any breakouts. Unfortunately, I cannot assess its effectiveness.

I have sensitive combination skin, and I am satisfied with the serum. After a week of daily use, my skin has become noticeably smoother and my complexion fresher. The redness has disappeared.

It didn't help me at all. It was too weak. My skin was greasier than ever before after using it. I switched to another serum and noticed improvements, and my skin wasn't greasy anymore. Maybe it will help as a first serum for dry skin.

I really liked the serum.

I didn't really like it. Each skin type requires its own care. It helps me more with getting rid of acne, but it doesn't calm irritation, on the contrary. The next day after using it, there may be slightly less acne.

Unfortunately, this serum didn't work for me either. It caused new breakouts and I didn't notice any specific effect from it.

I tried this serum to reduce irritation, but unfortunately it didn't help me. The texture is liquid and quickly absorbed by the skin, providing moisture. Personally, it didn't work for me, or rather it didn't help at all. To determine if it's worth buying, you would need to try it yourself because based on reviews, it has helped some people while others consider it a waste of money.

The serum itself is okay, but I bought it specifically to lighten acne spots, and it didn't help at all.

Great. Liked it.

Effect 0
This product might slightly even out the skin tone, but in my opinion, it's a waste of money. It won't be suitable for problematic skin at all.

Good day! I ordered a facial serum with lactic and glycolic acid. At first, everything was great, especially on my forehead, where the skin became soft and free from small blemishes. However, after two weeks of use, I started getting large pimples on my cheeks, which left scars as if I had scraped my face on asphalt. It took me a while to figure out what exactly in my skincare routine was causing this reaction. Maybe some products didn't agree with each other. It wasn't until I realized that it was this serum that was causing such havoc on my face. I had ordered from a different website the first time, and when I realized that this product didn't suit me, I canceled my order.

As for the downsides, I would also like to add that the packaging of this skincare product is very inconvenient. The dispenser is not user-friendly at all, and a significant amount of product would just go to waste until I transferred it to a jar with a dropper. I will definitely not be using this serum anymore, but I would advise changing the packaging to something more suitable.

I can't say anything bad about the serum, but I didn't notice any wow effect.

This serum is excellent and moisturizes the skin very well. It doesn't tighten or cause any redness or irritation. I have combination skin.

I experienced redness and a burning sensation on my skin. It was supposed to soothe the skin.

The serum is excellent and does not leave the skin feeling tight. After using it, my skin feels soft and even my small pimples have become less noticeable. I have not experienced any allergies, even though my skin is sensitive.

Oh, Sane, under every one of your products there is a bunch of fake praise reviews. Meanwhile, the products are useless. I bought two of your products and they are simply ineffective.

I fully appreciated the serum, probably after a month of consistent application. It's not that I didn't notice any changes before, I just didn't want to claim anything until I was sure that it was indeed improving the condition of my face. At first, it seemed like it was breaking out, but gradually it provided a gentle cleansing and exfoliation of unnecessary impurities. Probably after a month, my skin renewed itself, and that's when I started noticing both stronger and faster effects. The action is still gaining momentum, and now every morning I wake up and see my skin slightly changed, definitely for the better. I definitely liked the product.

I was satisfied with the serum. When I finally finished using up the remaining product in the jar, I reflected and regretted not taking a photo before starting to use it. I remember how different it was, the quality of my skin changed significantly, it immediately affected my appearance, and I feel healthier. That's the main thing...

This product is absolutely useless. It didn't get any worse, but there were no improvements either. It doesn't dry out the skin, which is a plus.
I have bought products from this company before, relying on reviews, but each time I am disappointed. The stylish design is tempting, but I won't be buying anything else.

This is one of the first products I ever bought from Sein, even before anyone knew about them. If I'm not mistaken, it was during the quarantine of 2020, or maybe even earlier. I distinctly remember sitting at home and applying the serum. When the lockdown was lifted, my skin looked incredibly well-maintained. Ever since then, I've been using this serum.

It provides minimal softening effect. If there are any changes, they are so subtle that I'm not sure if they can be attributed to this serum at all. I definitely won't be buying it again. My skin type is dry.

This serum didn't leave me indifferent; it somehow changed me. First and foremost, it changed my attitude towards skincare. I often felt lazy to do anything because it seemed complicated and time-consuming. But with this serum, I didn't have to do anything like that. I started using it every day, mostly before bed, and immediately noticed that my skin became more well-groomed. I even started receiving compliments. Because of this, I have grown to love taking care of my skin.

At first, I thought the serum was a miracle! My skin was clean and well-groomed, but after a couple of months of use, my face broke out and my pores became enlarged. I stopped using it, and everything was fine. I can't say anything good about it. We all hope to get a miracle product for minimal money, but in the end, you have to pay for a good product, and this serum is proof of that. This is just my personal review, it may work for someone else.

I don't mind spending money on this serum, whether it's this time or for future purchases. I think I will continue to do so. It has everything necessary to keep my skin clean and prevent constant breakouts. Additionally, the acids in its composition help exfoliate and leave my face super soft.

I really like this serum, it recently thoroughly cleansed my face. I continue to use it to maintain the effect.

The serum is excellent, it doesn't dry out the skin and provides hydration. I have sensitive skin and I didn't experience any irritation from the serum. I liked it and I highly recommend it.

I always make sure to reserve a spot in my skincare routine for this serum, specifically in the evening. No matter how much I've tested it, I've already confirmed that the serum works much better when applied at night. Of course, you can decide for yourself, but in my opinion, breakouts clear up faster this way.

I want to share my experience using this serum: it is very important (!) to apply it on completely clean skin after cleansing with any facial cleanser (soap, gel, foam, etc.) - only in this case (!) it will not leave a greasy film if you have combination/oily skin prone to breakouts. You should apply it in a small amount, just enough to lightly cover the face. I wouldn't say that the claimed percentage of acids is accurate here, but the serum is very gentle, soft, does not cause breakouts, and can indeed reduce different types of breakouts. So go ahead and try it!

This product is both a serum and a tonic in one. It provides cleansing, toning, moisturizing, and restorative effects, which I have personally noticed. This is amazing. However, it is recommended to test for allergies and perform a patch test on the hand before using.

As I understand it, peels are used more when the skin has more severe issues, while serums are for more normal skin types. The best part about serums for me is that you don't have to keep them on for a certain amount of time and then struggle to wash them off, like with peels. I apply the serum at night and nothing bothers me anymore. If my skin condition worsens a bit, I apply it a second time during the day, in the morning. Then I make sure to seal it with a sunscreen cream on top, even if it's just a minimum SPF, it should be there.

I have tried a similar peel with glycolic and lactic acids. I bought the serum for comparison because I liked the peel and was curious about the difference. I only noticed that the peel is more concentrated and can't be used as frequently as the serum. I can comfortably apply the serum every day, sometimes before bed, under moisturizer, and the results are good.

When I received this serum, I was very disappointed. What disappointed me was that the dispenser was completely open... no protective films, packaging, or box. Nothing! This is critical for me! Who knows how many people touched that dispenser?! How can I know that nobody tampered with the bottle?
And on top of that, there is some particle floating in the bottle that I cannot identify.
I will not use it because it's disgusting! Take some measures regarding this!

I fell in love with this serum long before I found out what a powerful brand it is and how much interesting and useful products they produce! I started using the serum blindly, and I never regretted it. I've already bought another jar for the third time. My skin has adapted to its positive effects and is constantly balanced. I no longer worry about severe breakouts.

I have a feeling that representatives of this brand write positive reviews for themselves, and in such large quantities too. I just can't believe that there are so many good reviews about such mediocre products. The cosmetics are just not worth it. I have tried many things, relying on reviews and my own naivety. The cosmetics from this brand simply don't work. Don't waste your money on them.

Unfortunately, it didn't work for me. I used it every evening on clean skin, but after a week, my skin had a completely different color in the morning, not a nice, dull color. I had more pimples and many inflamed ones. I have problematic skin prone to acne, so I found a good skincare routine and thought the serum would complement it, but no, it's not for me. I haven't used it for several days now, and in the morning, my skin looks good again. The number of pimples hasn't increased, and the inflamed ones have started to heal.

The serum left me with nothing but pleasant impressions. How could one not like a product that doesn't even require application instructions, as its usage is self-explanatory and provides instant results on the skin? I'm not a fan of meticulously following application charts for various products; I prefer to apply them every other day and not worry about it anymore. This serum allows me to do just that. After a month of using it, I can already see visible improvements.
