Know Your Ingredients: DNA

by Gio


What it is
DNA, which is short for deoxyribonucleic acid, is a molecule that holds genetic information. It is found in all cells.

What it does
Manufacturers claims DNA can fight the signs of aging by telling cells to produce more collagen, controlling inflammation and protecting skin from the sun, but so far nothing has been proved.

Side effect
DNA in skincare is controversial, and not just for the lack of studies supporting its potential effectiveness. If DNA worked as claimed (and it’s highly unlikely it does when applied topically), then it would affect the genes and you don’t really want to use anything that can do that. Any product that messes with genes has to be classified as a drug, not a cosmetic, and hence be subjected to much stricter regulations, to make sure it won’t have any dangerous side effects.

I know this ingredient far too well thanks to two years of biology class *shudder*. I wouldn’t want anything mutating my DNA unless it guarantees me teleportation with no side effects. 😀

I’m curious if DNA will ever do anything in skincare, not thousand dollar laser and light and what-ever-else-is-out-there treatments, but in creams and serums.

Janessa, I guess it’s possible that in the future they may come up with some sort of DNA extract that has some anti-aging properties or something, but I’m not sure I’d use it either. Not without being assured they did throughout tests for a decade or so to make sure there are no side effects. Messing with DNA can be dangerous, after all.

I think DNA products will be like lash growth products; both are eerie.

I agree. I don’t think I’ll ever try lash growth products either. They just scare me…

I guess “Know Your Ingredients” posts can be our convo posts haha! Anyways, I wanted to tell you that I really admire you for how sincere and respectful you are towards disagreements. I do read follow-up posts most of the time and wow, I’m amazed at how opinionated some are and I’m in awe at your patience to explain.

I see that (the above) as a sign of growth in your blog. As more and more stumble upon this gem, you’ll have better and worse incidences. But! In the end, you’ll always have so many more who love and support you!
