Trying toВ grasp atomic structures and ionic compounds in science wasn'tВ always all that thrilling. Yet poring over the ingredient lists on skincare products is practically a hobby. We all love hearing about the latest skincare ingredients to deliver big resultsВ and usually rushВ to the nearest shop to find them afterward. This is the kind of science we can all get excited about. So for strictly educational purposes, it's our duty to share something that might have had your eyes glazing over inВ chemistry, but with these serious skin claims, you'll want to know all about it.

We're talking about amino acids for skin. They're essential throughout the body but especially beneficial for your skin. To steer you in the right direction, we spoke with consultant dermatologist Justine Kluk, who gave us the full scoop.В


What are amino acids?

First up, why should we be paying attention to amino acids at all? We know skincare ingredients come and go in waves of popularity, but these are keepers. Kluk explains that "amino acids are the building blocks that make up proteins and have a role in virtually all the biological processes that occur in our bodies. The sequence in which they combine together determines which particular protein they will form and how they will function."

In other words, amino acids are vital components in making our bodies work, so it stands to reason that they'll also be able to work their magic on our skin, too.В


How do amino acids benefit skin?

As we know, science gets way more interesting when it leads to noticeable results, and amino acids for your skin certainly do, as they "promote cellular repair, hydrate the skin and provideВ antioxidant protection," says Kluk.В

We already have amino acids in the top layers of our skin, and they're very busy working on keeping our skin hydrated by pushing moisture through the skin. WeВ know the impact it can have when our skin is lacking moisture. Everything from dryness and rough textures to those pesky lines pops up-so we're all for an extraВ boost of hydration from amino acids.В


What are the best amino acids for skin?

Sold? Well, before you start rushing out to look for products, here areВ all theВ important details of what you should be keeping an eye out for. Kluk says thatВ "there are 20 known amino acids, some of which we make in our own bodies and others which we can't make on our own but get from our diet. All of these are important for good skin health."В

So there areВ two camps of amino acids: theВ essential ones that we have to get fromВ foods like fish, or even chickpeas, milk, or supplements. Then we also have non-essential amino acids, which the body makes for us. When you're looking for them in skincare, some of the acids that work well are arginine, lysine, histidine, glycine, and leucine


How can I add amino acids into my skincare routine?

We know there's a lot goingВ happening on your bathroom shelves, so luckily, amino acids don't require an entirely new step in your routine. They're just anВ addition that will make your products work harder. As Kluk explains, this is because "amino acids can combine together to form protein fragments known as peptides, which have been studied and proven to increase skin firmness and texture and to reduce wrinkles when applied topically to the skin."

While you can get some of the benefits from your diet or through supplements, it's clear that using amino acids in your skincare gives that extra boost. She adds that "if you would like to introduce these into your skincare routine, a moisturizer or eye cream would be a good place to start."
