If you ever wondered about using acid-based skincare products as part of your skincare routine, you're probably familiar with Alpha Hydroxy Acid (AHA) and Beta Hydroxy Acid (BHA). Most skincare brands have at least a few products with these key ingredients. But what are they? How do they help our skin stay flawless? And what's the difference between the two?
Well, let's start by defining what AHAs and BHAs are. These types of acids are categorized as hydroxy acids. And hydroxy acids help remove dead skin cells through exfoliation which allows new skin cells to surface. Some hydroxy acids you might have heard of are glycolic acid, lactic acid, and salicylic acid. We usually find these ingredients in skincare products (chemical peels) that are made to treat common skin conditions like acne. When these acids are topically applied, they smooth, tighten, firm, and brighten the skin.
The key benefits of both AHAs and BHAs are that they work as an exfoliant, provide moisture, and repair sun-damaged skin. The main difference between the two is that AHAs are water-soluble and BHAs are lipid or oil soluble.
Whether you choose to use alpha-hydroxy acids or beta-hydroxy acids, here is how your skin can benefit from them and the products you should try.
Alpha Hydroxy Acids Do It All

According to Healthline, alpha hydroxy acids are primarily used for hyperpigmentation, enlarged pores, fine lines, melasma, and uneven skin tone. Common alpha hydroxy acids include glycolic acid, lactic acid, malic acid, tartaric acid, citric acid, and mandelic acid. Most AHAs are derived from a plant-based source like fruits, nuts, and sugar cane, but lactic acid is sourced from milk. This means it's much gentler on the skin and safe to use on sensitive skin.
You can add AHAs a few times a week to your morning skincare routine. See how your skin feels or reacts to it. And be sure to use moisturizer and sunscreen to prevent burns or irritation.
Beta Hydroxy Acids Are Your Acne Solution
Compared to alpha hydroxy acids, there is only one beta hydroxy acid, salicylic acid, which it's derived from willow bark. Many over-the-counter facial cleansers contain salicylic acid as well because of its acne-fighting properties. In a Glamour article, dermatologist Robert Anolik, M.D. said, "BHA is lipophilic, so it's drawn to oils. That means it will not only exfoliate the top layer but also target the sebaceous glands down in the pores, clearing the clogs that create whiteheads and blackheads while also helping fade the pink marks that are left over from old outbreaks."
Salicylic acid can also correct dark spots without skin irritation because of its anti-inflammatory properties. BHAs can be used a few times a week too.
How To Use AHAs and BHAs

The beauty of AHAs and BHAs is that you can use them together. Try alternating each product by using one type in the morning and the other as part of your nighttime routine. You can use AHAs and BHAs on alternating days too. But never layer these two products together! Remember, these are acids that act as exfoliants—so they can cause dryness and irritation.
Make sure to use low concentrations because higher concentrations can irritate the skin. Anything with a concentration of 10% or less is what you want. If you're not sure, ask your esthetician or dermatologist how to incorporate these acids into your skincare routine.
Must-Try Alpha Hydroxy and Beta Hydroxy Acid Products
Alpha hydroxy and beta hydroxy acid-based products can be found at your favorite beauty stores like Ulta or Sephora. They can also be found at online skin stores like Amazon, Dermastore.com, or from your favorite skincare brands.
Here are a few trending AHA and BHA products you can try:
Neutrogena Pore Refining Exfoliating Facial Cleanser
The Ordinary AHA 30% + BHA 2% Peeling Solution
Clinique iD: Moisturizer + Concentrate for Pores & Uneven Texture
Drunk Elephant T.L.C. Framboos™ Glycolic Resurfacing Night Serum
Paula's Choice SKIN PERFECTING 2% BHA Liquid Salicylic Acid Exfoliant
SkinMedica AHA/BHA Exfoliating Cleanser
Herbivore Botanicals Prism 12 AHA + 3 BHA Exfoliating Glow Serum
I swear by The Ordinary brand because it's high-end quality and affordable AF, but try whatever beauty brand you like. The skincare brands I use vary, but I do include a medical-grade salicylic acid and glycolic acid scrub in my skincare regime. It helps with my acne, and I definitely feel the difference in my skin texture after one wash.
Listen, AHAs and BHAs are the game-changers you need in your skincare routine.
So, get your glow on sis.

I had the chance to sit down with the film’s director, Mark Anthony Green, to talk about what inspired this gripping story, how Ayo Edebiri brought something unexpected to the role, and what it was like creating such an immersive world. From cult-like devotion to the dark side of fame, Opus doesn’t just entertain—it makes you think. And according to Mark, that’s exactly the point.
"Best Time Ever"

Right off the bat, I asked Mark Anthony Green to sum up Opus in just three words. His answer? "Best time ever." Which, if you've seen the trailer, might sound a little ironic considering how intense the film is. But Mark laughed at my skepticism and added, "A little skepticism keeps us all safe."
And honestly, after watching the movie, I might be side-eyeing any future press trips myself.
The Inspiration Behind the Madness
With Opus tackling themes like power, isolation, and the cult of celebrity, I had to know—what sparked the idea for this film?
“There’s this thing I’ve been seeing, and that I think we all have been seeing—how tribalism and idolizing certain figures has become part of people’s identities,” Mark explains. “It’s pushed us away from each other, and it’s become more divisive. I started writing this film six years ago because of that. And, you know, sometimes when you work on a movie for that long, the thing you were grappling with becomes less relevant. But this? This has only become a bigger problem.”
And yet, Mark made one thing clear—while Opus has plenty of social commentary woven into it, the priority was making a wild, entertaining ride. "You described the film as wild, and that’s the highest compliment to me," he says. "I wanted it to be fun, and I wanted people to walk away talking about it."

Ayo Edebiri is best known for her comedic chops, but Opus throws her into a completely different arena. So, what made her the perfect choice for this dark, gripping role?
“The great thing about a talented actor like Ayo is they live for being uncomfortable and being challenged,” Mark says. “And Ayo is one of the most talented amongst the talented. People like that, they don’t shy away from something different—they run toward it.”
Mark couldn’t stop raving about her performance, admitting that even after seeing the film “two trillion times,” he still catches new details in her acting. "She makes these weird, brilliant choices, and I’m still in awe of what she did in this film," he says.
And beyond her skill? Mark just loves everything about her. “She’s gorgeous, she’s original, she’s always in a scene, even if it’s not her moment. I love her skin complexion, her background, her sense of humor. I started out as a fan, and now I’m her biggest fan.”
The Cult-Like Energy and Twisted Twists
Opus has a heavy psychological thriller vibe, with a mysterious, cult-like energy running through it. I asked Mark if any real-life events or films inspired its eerie tone.
His answer? “We recorded John Malkovich, The-Dream, and Nile Rodgers in a Boston studio before filming even started. That was the first moment this whole experiment really felt real. John hit a note, and everyone in the room just kind of looked around like, ‘Holy sh*t.’ It was electric. That alchemy of talent coming together—I’ll never forget it.”
And as for those jaw-dropping twists? Mark was very intentional about keeping the audience on edge. “I wanted every scene to make you question what’s real and what’s not,” he says. “If you think you know what’s going to happen, you’re wrong.”
A Fast and Furious Filmmaking Process
For such a visually stunning and layered film, you’d think Opus had a massive budget and months of shooting time. Nope.
“We shot for 19 days,” Mark reveals. “Which is nothing.”
And yet, the film doesn’t feel rushed at all. That’s thanks to an all-star crew, from the cinematographer to the costume designer. “We didn’t have an excess of resources, but we had incredibly talented people who overdelivered,” he says. “The film has a gravitas that our budget doesn’t reflect, and I’m so proud of that.”
Shoutout to the hair and makeup team, too—because Ayo’s hair was laid flawlessly the entire time. “And that’s not easy when you’re shooting out of order and on such a tight schedule,” Mark laughs. “It was an insane puzzle, but the crew made it work.”
Go See "Opus"—Like, Right Now
If you love thrillers that keep you guessing, Opus is a must-watch. It’s smart, stylish, and just unsettling enough to stick with you long after the credits roll. Plus, Ayo Edebiri in a leading thriller role? We need more of this.
So, consider this your official announcement: Grab your friends, your popcorn, and maybe a nightlight—because Opus is in theaters now, and you don’t want to miss it.
