I’m getting age spots on my temples and other places around my face. Started using this product around the end of January of this year 2025. Have gone through two bottles and just started on my third. It takes a while but this stuff absolutely works! You may see that some spots and freckles will disappear quite quickly while others seem to have no progress at all, but stick with it use it twice a day on the dark spots and you will start to see some remarkable improvement. At first it’s very slow but it ramps up almost exponentially as you keep using it. So I’m at nine months of usage now as it is September 20 25 and two bottles have resulted in remarkable progress and I am very much encouraged that the toughest of my spots are on the path to being gone. My advice is to apply it Only on the spots using the dropper massage it in vigorously for one to two minutes and then dab a little extra on top. Do this twice a day and you will make faster progress than I did. In the beginning I was skeptical and for the first few months was using it sporadically maybe once a day maybe once every other day But then I started to see some results and ramped up my frequency. I’ve tried a bunch of others before this and they didn’t make much progress, but this is the winner!

I’ve been using the La Roche-Posay Glycolic B5 Serum for a few weeks, and it has made a noticeable difference in my skin texture. The glycolic acid gently exfoliates dead skin cells, helping to brighten my complexion and reduce dullness. At the same time, the vitamin B5 deeply hydrates and soothes my skin, preventing irritation and dryness. The serum absorbs quickly and doesn’t leave any sticky residue. It’s suitable for sensitive skin like mine, and I haven’t experienced any redness or discomfort. After consistent use, my skin looks smoother, clearer, and more radiant. Highly recommend this serum if you want gentle exfoliation paired with hydration!

This is amazing. Like 100000/10. First 2 top pictures were taken 02/21/25 and the bottom 2 were 03/03/25. It hasn’t even been a month and there’s been a HUGE change. I’m amazed with the results. I also use a tumeric face bar & the la roche posay duo acne cleanser wash as well. I was going to purchase the purple stela b3 serum too but I’m seeing amazing results currently

I won’t buy this again because I know it’s gonna fix my problem in less than a week and I won’t needed again. I’m just impressed. I took the first picture at 11:34pm, second picture 1:22pm, 14 hours later and, I don’t know if I’m crazy but, are you seeing that change? I will keep using it. Be careful! It can burn a little bit, but you can use it a few days per week. It works.

I wish I could give this product a million stars! I have tried everything under the sun to get rid of my dark spots from acne and this is the only product that has given me results and not to mention in an incredibly short time frame. First photo with eyes closed is the before taken on May 15th and second photo is the after taken today June 20th. I do have a new spot along my jawline but it is clearing up as well but the dark spot on my cheek is practically gone! Coming from someone who only wore foundation to cover the dark spots left behind from the occasional break out, this product is now replacing my foundation entirely. HIGHLY RECOMMEND!

This serum works well! I have super sensitive, adult acne prone skin that is prone to hyperpigmentation so I’m always looking for serums that help correct that issue. This has helped quite a bit so for. It’s a fairly thick serum that absorbs into the skin surprisingly well. It also plays well with my other serums and my moisturizer, so there’s no pilling. It doesn’t dry out my skin either, which is nice. So far, I have zero complaints and would recommend to others.

This serum works well on hyperpigmentation but there are so things I don’t love about it. I do like the glass bottle. It’s coated in white to fight UV exposure. The label is pretty basic and doesn’t clash with anything on my vanity but it’s not particularly pretty. I dislike the smell. It’s smells like plastic and like…synthetic fruit. It reminds me of the old strawberry shortcake dolls from the 70s and 80s but the dolls smelled better. I don’t not care for the dropper. Most glass droppers taper to a small point, but this one just ends bluntly. When you’re moving the dropper from the bottle to your hand, there is often dripping because the base of the dropper is so wide open. This makes it spill on clothes, surfaces and the outside of the bottle. If you don’t wipe up the spilled excess, it oxidizes to a gross brown color. The product actually works great to reduce hyperpigmentation and soften and plump skin. This is probably the best effect I’ve gotten so far from a glycolic acid serum. However, I have seen similar results from using a 10%+ glycolic acid toner and a good moisturizer. Hope this info was helpful. Please hit the button if this info was helpful.

I have heard a lot about glycolic acid and wanted to give it a try. I have a few dark spots on my face that need some attention. The bottle has a dropper applicator for easy application. I put this on after washing my face in the evening. After using it for two weeks my skin does appear brighter. I will keep using this to monitor the results.

I’ve been using expensive skinceutical C E Ferulic and like it but it’s $166! This is about same size and price is 1/4! So I had to try. So far so good! I just started using it so I’ll update the review after I finish the bottle but I have sensitive skin and this does not cause any irritation or redness. Hydrate my skin and a little goes a long way! I’ve heard good things about La Roche and can’t wait to see the result!

I enjoy using this dark spot serum. I live in Colorado where it’s sunny almost everyday. The serum has been great help to fade, erase my dark spots including freckles too. Here’s what I think about the product below, Pros: - great eco friendly packaging : box, container are made with recycle-able materials. Yay! - actual science behind the product : the product is scientifically proven to reduce dark spots Cons: - haven’t found any Overall, the product works very well on my sensitive skin so far. I easily get tired eyes after work. I put this serum every night. I would say price is slightly higher. But, I believe the product is worth every Penny in my opinion. I would recommend this product to anyone who’s looking for a great dark spot reliever.

Honestly I’m skeptical of all these products no matter the cost. I really wish one would work consistently, and I keep trying different ones, but I think only freezing and removing these spots by a dermatologist is the answer. I’m not trying to hide aging, I still look good, but still we like to hold on to our clear skin for as long as possible. So, I’m trying this one on two spots and lemon juice on another . And I’ve had a lot of success with Aloe Vera for skin issues , but not particularly brown spots . I’ll give it 4 stars for a nicely packaged product and ease of use and I promise to come back and scream a five star review if this works for me . Good luck to everyone else too 🙏

It smells like wine to me, like fruit and alcohol but the scent vanishes after being applied. It absorbed really quickly which I appreciated since it didn't add much more time to my routine. Since it's only for night use I didn't try it under makeup but it didn't pill or react adversely to my moisturizer. I have a few particular dark spots that have been bothering me and vitamin C serums etc. haven't done the trick. I also have a very uneven skin tone in general. I was hoping for some noticeable results but nothing yet. I took a before photo so I'll keep comparing and hopefully I can upload results if anything changes.
