Light Up Intensifier Serum

Skin Type & Concerns: Oily | Tolerant | Pigmented | Firming

Texture: Lightweight, like water.

I use this as a wet compress for my skin after it has healed from a gold microneedling treatment. It really is effective at preventing post-inflammatory hyperpigmentation (PIH) and inflammation.

I mix 5ml of purified water with 5ml of this tranexamic acid serum, soak a compressed paper mask, and apply it as a compress. When I use it this way, it gets used up very quickly.

I've already stocked up on the 10-bottle set.

Before a sunny vacation last month, I asked my dermatologist what to use for post-sun care. He recommended a consistent routine with Tranexamic Acid to help with inflammation and brightening. I decided to bring this serum with me, and it was a total lifesaver!

It worked perfectly to calm my skin after a day in the sun and helped prevent those stubborn dark spots from settling in. My blotchy, reddish "vacation skin" cleared up so much faster than usual. The texture is the best part - it's literally as lightweight as water, so it never feels sticky, even when I apply 2-3 full droppers.

I used it twice a day for a month and have already gone through two bottles. It has become a staple in my routine!

Skin Type: Sensitive, Oily/Dehydrated, Prone to Post-Acne Marks
Duration of Use: About one month

I've been using this for about a month now and I'm so impressed. The texture is incredibly lightweight and watery- it absorbs in seconds with zero stickiness, which is a dream for my oily skin.

The main ingredient is Tranexamic Acid, and this formula is gentle enough that I had no irritation or need to build up a tolerance. I love how easily it layers with my other products (even my Vitamin C serum!) without any conflicts or pilling. My main goal was to fade my red post-acne marks, and this has definitely sped up that process. I've also noticed my overall redness is slowly but surely calming down.

While it's not a deeply hydrating serum on its own (I still use a moisturizer), its performance, especially for the price, is fantastic compared to other Tranexamic Acid serums. Highly recommend!

The value you get from this product is just insane. The texture is so lightweight and refreshing that I've started using it like a toner right after cleansing, and it's affordable enough that I can be super generous with it without feeling guilty!

It's perfect for my oily, acne-prone skin. It does an amazing job of calming down my redness and helping with the post-acne marks. If you're a night owl with reactive skin, you need to try this. It's become an absolute staple in my routine.

My dermatologist, who performs my monthly IPL (photorejuvenation) treatments, actually recommended I consistently use a Tranexamic Acid serum to help with overall brightness and redness. I chose this one from Sounder One, and it's fantastic.

After finishing a whole bottle, I've noticed my skin is much less prone to redness. (Full disclosure, I know the monthly IPL helps, but this serum has made a real, noticeable difference in maintaining my results!).

The best part, however, is the texture. Compared to other 5% Tranexamic Acid serums I've tried, this one is by far the most elegant and refreshing. It's completely water-light, absorbs instantly, and never feels sticky or foams up under other products. It's the perfect supporting product for a professional treatment plan.
