Fish Sperm For Younger Looking Skin?
What is Fish Sperm Skincare and why is it a trend?
In 2025, there will be skincare brands, including luxury ones, selling products made from fish sperm.
And people will actually be using them.
They don’t call it that. You’ll see names like marine DNA, spermidine, or salmon DNA extract in the ingredient list.
Sounds fancy, right? Until you realise it’s harvested straight from fish testicles.
This is the beauty industry, folks, where nothing is off-limits if you slap a £200 price tag on it.
What exactly is in Marina DNA creams?
Let’s break it down:
Fish sperm contain DNA fragments, nucleotides, and proteins.
Some labs believe these can support cell regeneration when applied to human skin.
The logic is:
- DNA = cellular repair
- Fish sperm = concentrated DNA
- Therefore, fish sperm = younger-looking skin
Except… science doesn’t back this up.
There’s very little clinical evidence that fish sperm extract applied topically does anything meaningful long-term. It’s more hype than hard proof.
The Negatives of Fish Sperm in your skincare?
To get that “marine DNA,” brands harvest milt the sperm sacs of fish like salmon or herring.
Unless the fish are particularly tolerant of the process, it usually involves killing the animal.
I don’t care how natural or scientific it sounds. If the ingredient can’t exist without ending a life?
That’s not skincare. That’s a problem.
Does Marina DNA work in Skincare?
In a word, no.
Could there be short-term benefits? Maybe.
Is it revolutionary? No.
Would I put it on my face? Hell no.
Plenty of proven natural ingredients like olive-based hydroxytyrosol, caffeine, and niacinamide boost skin repair without collecting bodily fluids from marine life.
Why this matters
I started &SOM Skin because I was horrified by what the industry hides in their labels.
This fish sperm trend is another example of how disconnected the beauty world is from common sense and compassion.
If your product needs a dead fish to “work,” it’s probably not worth using.
