Let's talk about fruit acids. Maybe you've never heard of them—and if you have, you’re probably wondering what they do, or how to get your hands on some. Here’s what you need to know...

What is Fruit Acid Complex or Multifruit Complex in Skincare?

Simply put, Fruit Acid Complex, or fruit enzymes, are naturally derived from fruit. Technically speaking, it’s a blend of five botanical extracts: bilberry, sugar cane, sugar maple, orange and lemon. These extracts contain several naturally occurring alpha hydroxy acids, which have been shown to promote smoother skin by increasing the rate of cell renewal.

These fruit acids are super effective, yet gentle enough for daily use—unlike synthetically derived acids like glycolic, lactic or salicylic acids, which can be irritating and may accelerate the aging process if overused. The best part? Fruit acids are mild enough for sensitive skin and totally safe to use during winter. Basically, these enzymes lightly exfoliate and clear out your pores without drying or stripping your skin.

The bottom line: these hard-working multitaskers help clear blemishes, hydrate your skin and lighten pigment spots by loosening layers of dead cells clinging to the skin’s surface.

3 Benefits of Fruit Acid Complex or Multifruit Complex in Skincare?

Here are the top three reasons why your skin will benefit from these super-effective fruit AHAs:

1. Clears + Brightens Complexion

The Results: According to the University of Maryland Medical Center, AHAs help to remove the top damaged layer of skin, revealing healthier, glowing skin beneath.

The Science: Fruit Acids help to clarify your complexion by turning over skin cells more rapidly—especially those stubborn skin cells that tend to get stuck in pores and cause breakouts.

2. Naturally Lightens Skin

The Results: Move over, hydroquinone! Fruit acids have been found to be just as effective at evening out your complexion, but so much safer.

The Science: These AHA’s help to inhibit melanin formation that cause the discolorations from scars and hormonal changes.

3. Increases Absorption

The Results: Fruit Acids optimize your skin's absorption level, so you get the maximum results from your favorite skincare products (think: essential nutrients + effective ingredients like niacinamide).

The Science: Surface debris and dead skin cells inhibit your skin's ability to absorb the active ingredients in your serums and oils. Alpha hydroxy acids remove these surface deposits to expose the underlying cells.

Where Can You Find a Gentle, Yet Effective AHA Serum?

At Otto Skin Goods, we chose to focus on fruit acids in our Multitasker Night Serum, because we feel this is a safer alternative to synthetically derived glycolic and lactic acids. While glycolic and lactic acids are great to work into your routine on an occasional basis, regular use can actually damage your skin barrier and accelerate aging. True, our fruit acids take slightly longer exposure to see all the amazing benefits it has to offer—but we like to think of this as its superpower! You’ll be seeing beautiful, healthy results in less than just a few months, without the potentially harmful effects of more potent acids. Get ready for refreshed, glowing skin, even in the winter! Shop Now.

Frequently Asked Questions

What exactly are fruit acids, and where do they come from?

Fruit acids, also known as Fruit Acid Complex or Multifruit Complex, are naturally derived alpha hydroxy acids (AHAs) sourced from five botanical extracts: bilberry, sugar cane, sugar maple, orange, and lemon. These plant-based acids work to gently exfoliate the skin and promote cell renewal.

How are fruit acids different from synthetic acids like glycolic or lactic acid?

While glycolic and lactic acids can be effective, they are synthetically derived and can be irritating to the skin—especially with regular use, which may damage your skin barrier and accelerate aging over time. Fruit acids offer a gentler, naturally sourced alternative that's safe for daily use and suitable for sensitive skin.

Can I use fruit acids if I have sensitive skin?

Yes! One of the biggest advantages of fruit acids is that they are mild enough for sensitive skin types. They gently exfoliate and clear pores without drying or stripping the skin, making them a great option even for those who typically react to stronger acids.

Are fruit acids safe to use in the winter?

Absolutely. Unlike harsher acids that can leave skin vulnerable to the elements, fruit acids are gentle enough for year-round use—including the colder, drier months when your skin needs extra care.

How long does it take to see results from fruit acids?

Because fruit acids work gently and gradually, results may take a little longer to appear compared to more potent synthetic acids. That said, most people can expect to see noticeable improvements in skin clarity, brightness, and texture within just a few months of consistent use.

What skin concerns can fruit acids help address?

Fruit acids are true multitaskers. They can help clear blemishes, brighten and even out your complexion, lighten pigmentation and dark spots, and improve your skin's ability to absorb other active ingredients in your skincare routine.

Where can I find a skincare product with fruit acids?

Otto Skin Goods features a Fruit Acid Complex in our Multitasker Night Serum, formulated as a safer, gentler daily alternative to traditional AHA serums.
