Why You Should Add Amino Acids To Your Skincare Routine

skincare benefits of amino acids

The best skincare ingredients are SO underrated.

Take amino acids, for example.

Amino whaaaaaaat?

Exactly. Amino acids are the building blocks of all proteins. They make up 75% of the human body!

They’re essentials to almost all of its functions, including the synthesis of collagen. There is no way skin can function without them.

And yet, everyone ignores them. Go figure 🙄

What happens when skin doesn’t have enough amino acids?

You can always tell when skin lacks amino acids. It ain’t a pretty picture:

  • Amino acids are involved in the production of collagen and elastin, which keep skin elastic and firm. When amino acids become scarce, skin gets thinner.
  • Amino acids hydrate skin. The fewer are in the skin, the rougher it becomes.
  • Amino acids help skin heal faster. Without them, the healing process slows down to a snail’s pace.

How do I spot an amino acid in the ingredient list?

Now you know why you have to add them to your skincare routine. But, how do you spot them?

There are around 20 different amino acids. 8 are called essentials because you can only get them through food. These are:

  • Isoleucine
  • Leucine
  • Lysine
  • Methionine
  • Phenylanine
  • Treonine
  • Tryptophan
  • Valine

Other amino acids can be synthetize by the body. They are:

  • Alanine
  • Arginine
  • Aspartic acid
  • Cysteine
  • Cystine
  • Glutamic acid
  • Glutamine
  • Glycine
  • Histidine
  • Proline
  • Serine
  • Tyrosine

What are the most common amino acids used in skincare?

Good news. You don’t have to remember them all! Phew!

Of course, the more amino acids you use, the happier your skin will be. But some amino acids work better than others. They hydrate skin, speed up the healing process, make wrinkles look smaller and even soothe irritations.

Here are the main ones you should look out for:

Arginine

Glutamine

Glycine

Histidine

Leucine

Lysine

Proline

Tyrosine

Helps other ingredients (especially proteins) penetrate the skin.

Obsessed with skincare as I am, I must say I’ve never given amino acids much thought! Thanks for the list of products — I would not have known where to begin without it. I love the Truth in Aging website and now I have an excuse to go there. 🙂

Laurie, it’s a shame that so many great ingredients are little known, isn’t it? Especially when the beauty industry discovers a new “miracle worker” every day. *sighs*

Susan, the easiest way is to find a moisturizer or serum with amino acids. If you don’t want to change your current products, The Ordinary has an amino acid product you can use before moisturizer.
