little known anti-acne ingredients

Got acne? Back in the day, you’d be drying your skin with benzoyl peroxide, exfoliate with salicylic acid twice a day every day and add a witch hazel toner to the mix… and then you wondered why your acne came back with a vengeance. Truth bomb: drying out acne dries out skin, too.

When skin is dry, it plays all sorts of tricks on you. It stings and flakes. Your skin’s pH level goes through the roof. Your protective barrier breaks down so that everything irritates it. Cue inflammation, excess oils and breakouts. Those days are over.

Don’t get me wrong. You can still use your salicylic acid and benzoyl peroxide – they do get the job done. But they’re not enough. If you want to make acne heal faster and keep the breakouts away, you need to give them a helping hand. Here are 3 little known anti-acne ingredients that help you clear up your skin faster:

Little Known Acne-Fighting Ingredient #1: Zinc

Zinc is a trace metal found in meat, nuts, whole grains, legumes and… your body. It helps wounds heal faster, protects broken skin from external, harmful stimuli and kicks acne’s ass. Zinc fights acne in two ways:

  1. Regulates oil production: When your skin pumps out too much oil, the excess gets stuck in the pores – together with dead skin cells and bacteria. The clogged pore ruptures and a pimple rears its ugly head. Zinc tells the hormones that make sebum to slow down production to keep that from happening.
  2. Soothes inflammation: zinc has anti-inflammatory properties that reduce inflammation. Guess what acne is? An anti-inflammatory disease!

Now, here’s the catch: zinc alone can’t kill P. Acnes, the bacteria that is making your life miserable. If you’re dealing with active acne, you’d still need benzyl peroxide or another of the acne killers below. BUT, if you’ve got acne-prone skin, adding zinc to your skincare routine helps the breakouts heal faster and prevents them from coming back.

Little Known Anti-Acne Ingredient #2: Azelaic Acid

Azelaic acid is the unsung hero of skincare. A dermatologist’s best-kept secret, it’s only now starting to get the recognition it deserves. Made by the bacteria and yeast that live on your skin, azelaic acid is one of the most effective acne-treatments out there. Just to give you an idea, here’s how it compares to other common acne remedies:

Little Known Anti-Acne Ingredient #3: Linoleic Acid

Linoleic acid is an omega-6 essential fatty acid. Essential means your skin can’t produce it. And that’s the problem. You see, healthy skin has a lot of linoleic acid. But when you have acne, its linoleic acid content plummets to the ground. It makes sense that adding linoleic acid back into the skin helps you fight acne. Here’s how:

  • It promotes exfoliation: Linoleic acid plays a key role in the natural exfoliation process.  When your skin doesn’t have enough, dead cells get stuck on your skin and into your pores. There, they mix with excess oil, get infected with bacteria and erupt in pimples.
  • It regulates oil production: Sebum production gets out of control when the enzyme 5α-reductase turns testotesrone into α-dihydrotestosterone. Linoleic acid can inhibit the activity of 5α-reductase, keeping oil production under control.
  • It has anti-inflammatory properties: Linoleic acid can soothe inflammation, the main cause of acne.

Like zinc, linoleic acid can’t single-handedly rid you of acne. But, together with azelaic acid (or another P. Acnes killer), it helps acne heal faster and keeps it from coming back. So where do you find linoleic acid? Oils. Here are the best ones for the job:

  • Evening Primrose oil (75%)
  • Grapeseed oil (72%)
  • Hemp seed oil (55%)
  • Rosehip oil (45%)
  • Safflower oil (68%)

For the love of your skin, avoid oils high in oleic acid. If in doubt, stick to the list above. If it ain’t there, don’t try it!

FAQs

How long does it take for zinc to work on acne?

Ugh, okay so don’t shoot the messenger, but you’re looking at like 8-12 weeks. I KNOW. It sucks waiting that long when you’ve got a face full of zits right now. But here’s the thing – zinc isn’t just covering up the problem, it’s actually fixing what’s broken. You might see your skin getting less greasy after a few weeks, which is cool. But for the breakouts to really calm down? Yeah, give it 2-3 months. The upside is once it works, it WORKS, because you’re not just treating symptoms anymore.

Can you use azelaic acid and salicylic acid together?

Hell yeah you can! But don’t be a hero and dump both on your face at once on day one. That’s a one-way ticket to Irritation City. Start slow – maybe salicylic in the morning, azelaic at night. Or do them on alternate days. After a week or two when your skin’s like “okay, I can handle this,” then you can layer them if you want. Just remember: thinnest consistency goes on first. And if your face starts screaming at you (red, flaky, angry), back off.

Which oils are worst for acne-prone skin?

Okay so coconut oil needs to get cancelled for acne-prone skin. I don’t care what your favorite influencer says – it’s pore-clogging garbage for us. Same with olive oil, avocado oil, and almond oil. They’re all loaded with oleic acid which basically rolls out the red carpet for clogged pores. Look, I get that they sound natural and nourishing but they’re a disaster. Stick with rosehip, grapeseed, or hemp seed oil instead – those are your actual friends.

Should you use niacinamide or azelaic acid for acne?

Honestly? Both if you can swing it. But if you’re making me choose: grab azelaic acid if you’ve got active pimples happening RIGHT NOW because it’ll actually murder the bacteria. Go for niacinamide if you’re more dealing with oiliness and redness. But real talk – they’re like the dream team together. Niacinamide builds up your skin’s defenses while azelaic acid goes to war with your acne. Just don’t dump them both on at once – introduce one, wait a week or two, then add the other.

Can linoleic acid make acne worse initially?

Nope, not really. It’s not like retinol where you go through that nightmare purging phase. If you start breaking out after adding a linoleic acid oil, either that specific oil hates you OR you’re going way too heavy-handed. Start with like 2-3 drops – seriously, that’s it. If you’re still getting zits after two weeks, that oil just isn’t the one for you. Not every oil works for everyone, even the “good” ones.

The Bottom Line

Fighting acne isn’t all about killing the bacteria P.Acnes. If you want to make the breakouts go away faster and keep them gone, you also need to regulate oil production, soothe inflammation and exfoliate skin regularly. These little known anti-acne ingredients will help you do just that.
