I’m using it and so far I really like it. The serum is lightweight, absorbs quickly, and doesn’t leave my skin sticky. From the first few days, my skin felt more hydrated and looked more even. I’m still testing it to really see the results on dark spots, but it hasn’t caused any irritation or breakouts. I like how it leaves my skin soft with a natural glow. So far, it’s doing great and I’ll keep using it. Read more

Best serum I’ve ever used. In less than a month, my acne marks started fading noticeably, and my skin looked clearer and brighter. I honestly didn’t believe the hype when I kept seeing it on TikTok and had pretty low expectations, but this proved me wrong. It boosted my confidence in my bare skin. Compared to the serum I used before that cost $48, this is a much better deal. It lasts over a month even when used twice a day (and even longer if used once daily). It’s very hydrating to the point where I sometimes don’t even need a moisturizer afterward. My bottle lasted about six weeks, and the results have been amazing: lighter dark spots, clearer skin, and a real glow. Read more

This serum appears to be lightening my melasma slightly, though I can't say for certain if it's solely this product or a combination of changes I made - switching from chemical to mineral sunscreen and stopping my vitamin C oil around the same time. That said, I'm seeing improvement, so I'm happy to keep using it. The dropper delivers just the right amount of product without waste, and my skin doesn't feel oily or sticky after application, which is a huge plus. I use it once a day right after cleansing as the first step in my routine, then follow up with salicylic acid for spot treating, PDRN cream, and mineral sunscreen. The serum absorbs quickly and layers well with other products without pilling. The niacinamide and tranexamic acid combination seems effective for brightening and evening out skin tone. For the price point, it's excellent value for money - K-beauty serums with these active ingredients are typically much more affordable than Western brands with similar formulations, and you get a decent amount of product that should last a couple months with daily use. If you're dealing with hyperpigmentation or melasma, this is worth trying, just be consistent and patient with results. Read more

This is a great product overall. To start off, I gradually integrated this serum into my skincare routine out of fear of upsetting the delicate balance of my combination skin - one drop every other day. In the first 2-4 weeks, I would see some small white heads here and there. When this happened, I'd minimize the amount of product used each day and/or the frequency in which I used it. 4 months in, I'm starting to experience some positive results. My skin tone has evened out overall. No more dark patches or spots. If I get a pimple, it clears, with minimal PIH. After a week or two, the spot is gone. Additionally, this serum helped me clear my combination dark circles (excess pigmentation and slight hollowness). Presently, I add three drops to my under eye area before using a topical retinol. I found this method to be a better course of treatment than OTC eye creams who advertise fixing this issue. Why? Because I was slowly able to customize the amount of niacinamide added to my under eyes over time, rather than shocking this skin with a new product all together. I don't like how this product is advertised by influencers - using two droppers full on the face in one sitting. I've found that if too much product is used on my skin, it becomes extremely sticky and uncomfortable. Half a dropper is enough when paired with consistency. Also, this serum has a higher concentration of niacinamide. So if you use other products with high concentrations, it could cause some irritation, inflammation, and hyper pigmentation. Hence, why I started low and slow. For full transparency, below is my skincare routine. I'm finally able to phase out make up, favoring tinted skin care products. But the key was going slowly with each product, adding one at a time and monitoring changes throughout my menstrual cycle. I'm 32. AM - Panoxyl (4%) - 10% Azelaic Acid - Vichy Mineral H.A.

This is one of the best products I’ve used for face acne and dark spots. The droplet formula is easy to apply, absorbs quickly, and helped clear breakouts while fading acne marks with consistent use. Just make sure to use sunscreen, because sun exposure can make dark spots worse while using this. Simple, effective, and worth it. Read more

I purchased the Niacinamide. When I first started using this, I started breaking out really bad. BUT I did even more research and the type of breakout I was experiencing was simply the product working. I trusted the process and kept going and can see a difference in my skin. The breakouts have calmed down and my skin is getting softer and clearer. Also, don’t mix this product with other heavy products like retinol etc. Pick one to use at night (I alternate) and I noticed the change. Using too many disrupted my skin and caused it to get too dry. Read more
