[REVIEW] Sidmool Secret Of Red Astaxanthin Concentrate

Sidmool Secret Of Red Astaxanthin Concentrate was purchased by Cosmeperks.

I’d normally wouldn’t even consider getting a new serum. I simply have way too many (not to mention that I just bought a new one only one day before this was recommended to me!). Even though I’m not in need of any serums, I was still very curious to see what astaxanthin is and why Sidmool makes it seem so amazing!


The Sidmool Astaxanthin Secret of red serum doesn’t have any dramatic claims or a lot of promises. They leave it all to the title since the high Astaxanthin content on its own is very extravagant. This product claims to be able to keep the skin bright and shining while making it more elastic.

Volume: 30ml

How to use:

Use twice a day. After removing makeup, washing and toning your face, apply an appropriate amount and gently tap around the eyes or spread over face while patting gently. After using, seal it with some moisturizing cream or sunscreen- depending from the time you are washing your face.

My skin type: Sensitive, acne prone and oily.

Sidmool Secret Of Red Astaxanthin Concentrate Review:

With a quick search I discovered astaxanthin is a keto retinoid that is supposed to be one of the most powerful antioxidants found in nature and it has been shown to help improve skin moisture levels, elasticity, and smoothness while reducing wrinkles, freckles, and spots.

I also discovered that astaxanthin is supposed to be 6000 times more powerful than vitamin C. Yes, you read that right. 6000 times! I’d get hyped even if it was just twice as powerful as vitamin c but 6000 times!? This must be very good.

There are few things that I want to say about this product before I get more in depth. First of all, the packaging. The box is very cute, it has small details that I love and everything but the actual container…that’s a no-no.

I can already see myself getting angry over that last bit that the straw won’t be able to reach and also, it’s a bit annoying when you press it to get some of the product out, since pressing it slowly makes the serum go on the container and pressing it too hard makes it splash on everything.

Secondly, the texture. I was very surprised when it arrived to see how watery it looked! After I used it, I was even more surprised at how oily it felt and smelled. My skin does absorb it but it takes a while and it feels a tiny bit oily. Also, because of its watery composition, it does run out pretty fast.

The serum is quite orange/red and that’s due to its high content of astaxanthin (98%!!!). Basically, Astaxanthin is what gives the red pigment to many fish that contain it. When you spread the serum the pigment thankfully vanishes.

This serum has an oily smell that personally reminds me of a mixture of the Hypericum plant (also known as Perforate St John’s-wort) and beeswax. It also gives off a perfumey smell but it’s very faint due to the strength of the oily smell.

As far as results go, I had huuuuge expectations and sadly was a bit disappointed. The thing is, I foolishly expected this product to clear my acne but all it did was make my face more moisturized – which isn’t a bad thing at all, just a reminder that price and results are proportional.

There was just one spot on my face where I got actual results. I’ve been getting these tiny wrinkles on my forehead for the past year and they’ve been really annoying. Furthermore, I also get tiny pimples from time to time on it too.

After using this serum both have started becoming less noticeable. Also, my forehead has become quite bright! It used to be dry but now it’s just normal. As far as the rest of my face goes, I got no results. It’s actually more appropriate to say that my acne have’t worsened but it pretty much looks the same.

It was nice trying out astaxanthin on my skin but as we all see, it’s not for me. A kind reminder, because it didn’t go that well in combination with my skin, it doesn’t mean it won’t work on you. I’ve seen plenty of people saying it completely cleared their skin.

Still however, be cautious about it. I won’t repurchase this one (obviously). I’ll stick to BHA and niacinamide. I’d recommend this to you if you’re looking for a cheap serum and you have clear skin with newly formed wrinkles.
