I spent a whole afternoon reading all sorts of research papers on this. You know, those lengthy, boring documents with all the charts and scientific jargon. I tried to make sense of it all, but honestly, most of it went over my head.

Then, I went to the store. I spent at least two hours in the skincare aisle, checking out different products. I grabbed anything that said “algae” on the label, and started to read the ingredients.
Here’s what I found:
- Most of these products use brown algae. I guess it’s like the main kind of algae for skincare. They say it’s full of antioxidants, and good for keeping your skin moist and elastic.
- Some products had red algae too, especially this one called Irish moss. It seems like they use it for similar reasons as the brown algae.
- There were a few other types of algae extract. They all claim to do different things, like fight UV rays, help with wrinkles, and even make your skin less inflamed. Sounds like they’ve got all kinds of antioxidants.
After looking at all these products, I started to compare the amount of algae in each one. This was tough because the labels weren’t always clear. Sometimes they’d just say “algae extract” without telling you how much. Some of them are just trying to make you feel like you’re getting a lot of algae, but the amount is so small, it might not even do anything! And don’t even get me started on those products that claim to have this super rare algae from some remote ocean. It sounds fancy, but who knows if it’s true?
So, I decided to do a little experiment. I bought a few of the products that seemed to have a decent amount of algae. I used them for a few weeks, and tried to see if I noticed any difference in my skin.
To be honest, I didn’t see any huge changes. My skin felt a bit more hydrated, maybe, but nothing drastic. Of course, everyone’s skin is different. Maybe these products work wonders for some people, but for me, it was just okay. It feels like algae is just a trendy ingredient right now, and companies are using it to make their products sound more natural and effective. Maybe there’s some truth to it, but it’s hard to tell without doing some serious testing.

My conclusion
Skincare products usually contain a small percentage of algae, often not enough to make a big difference. Most of the time, brown algae is used for hydration and elasticity, but the amount varies a lot. Many of the claims about algae seem to be based on very general research about its benefits, not specific studies about how much is needed to see results.
