who we are

Sally Olivia Kim Founder & CEO

Sally discovered the power of ingestible skincare after severely burning herself. She started drinking collagen to help with recovery, and after falling in love with it, she embarked on a journey to bring collagen to her everyone around her.

She began formulating with her favorite superfoods to make delicious collagen-infused drinks known as Crushed Tonic.

Sally has also published the book “The Collagen Glow.

Our Values


We're here to reject the gender-binary-ness of skincare. Men have skin too! Which is why we designed a product that was minimalist, gender-neutral, and strayed far from using gender-prescriptive language.

That's not all: we formulated 3 distinct flavors so that there was a flavor that worked for just about everyone: coffee drinker? Add our original crush to your cup of joe everyday. Hate coffee but still crave caffeine? Go with our matcha crush. Feeling sick? Take the turmeric crush. Busy? Traveling? That's why it's in a stick. We can go on, but the point is: we don't just believe in what we do. We believe in our how.


Our founder's obsession with skincare began when she got badly burned from an oil accident, and she had to figure out how she could get her skin to heal and regenerate as fast as possible.

But after experimenting with every topical solution out there that pretty much did nothing, she realized that the most important aspect of skincare was actually far from lotions and gels-- it was actually about what she put into her body, what she absorbed at the cellular level.

45 Calories in 1 stick, 10g of protein. no sugar. no fat. no carbs. All-Natural. Non-Gmo Fish. Ingredients all individually sourced from France, Japan, and USA. Manufactured in the USA.

You may have heard that supplements aren't regulated by the FDA, and that sounds scary. But don’t worry: we have partnered with certified manufacturers are suppliers that have more than done their homework. our probiotics are generally regarded as safe (GRAS) by the FDA, and our manufacturer is BRC-certified.


But not the 10-step routine you're thinking.

Despite all the craze around the ten-step Korean skincare regimen, we know that the most vital (yet still somehow unspoken) component of our skincare routine, is not another cream or lotion, but our diet. Korean cuisine is inherently gluten-free, dairy-free, full of minerals, and most importantly, laden with probiotics and collagen.


Our marine collagen is clinically proven. That doesn't happen often. And it doesn't stop there. Our collagen is traceable back to its roots, where it was sustainably sourced (collagen is extracted from fish skin, the parts of the fish that is usually thrown away).

We will always use marine collagen over bovine collagen. Because collagen from left over, boiled cow hides? No thanks. But of course, having all these standards, does come at a price. Our marine collagen is expensive and so are our probiotics. But they're the core of our products, so we couldn't have done it any other way. Our collagen is expertly extracted, sterilized and filtered and our probiotics are strong, survivable and backed by over 20 published studies.To buy just a good probiotic would cost you anywhere between $25-$65 a month, and pure high quality marine collagen costs around $40-50. So we've worked really hard to give you the best but also give you good value for your hard-earned money.


Yes, there's clinical proof that this stuff works. but effective doesn’t mean that it can’t be enjoyable, too. Our tonic is so delicious, and refreshing, that you'd have no idea it was so good for you. And as for results? You'll become the best version of yourself in 2-4 weeks, depending on how consistent you are. Just ask our guinea pigs!

When we first started thinking about how to combine our core ingredients in a simple and easy-to-use self-care routine, we knew that whatever we made had to taste great.

We're not big fans of handfuls of pills, and we wanted you to wake up in the morning, and look forward to your wellness routine. Most importantly, our marine collagen is tasteless: you would never guess that there were 10 whole grams of fish skin in each drink!


We think that the obsession with anti-aging is overrated. Aging isn't a crime. Which is why for us, the term anti-aging means something different: it’s about saying no growing up. It’s about rewinding time to get back to when we felt like we had all the energy in the world, to do whatever we wanted to do, nothing to hold us down, and no excuses to hold us back.

We formulated with essential building blocks of life to fight inflammation, indigestion, mineral deficiency, and fatigue-- everything our body needs more of at the cellular level. So that we'll get your youth back, where it really matters: within.

Frequently Asked Questions


We recommend around 10g to 20g daily. For best effects on hair and skin, please make sure to consume daily as our bodies cannot store extra amino acids overnight!

Probiotics can help your digestion feel better in hours. The benefits of collagen, however, may take up to 7 days for skin and 14 days for hair.

Our marine collagen itself is so pure and flavorless that you would have no idea that it's made from fish! We needed our drinks to taste delicious, so it was important for us that you couldn't taste the collagen powder (there is often quite prominent smell in other collagen brands). We tested, tasted and vetted through hundreds before landing on our specific formula of collagen and superfoods!

We recommend around 10g to 20g daily. Like all protein powders, it is more about consistency and sticking to it daily than taking too much! However, it is also important you are taking at least 10g daily!

We recommend before any food in the morning; however, it can be taken anytime: before gym, for good night’s sleep, etc. For those who do not consume as much protein on daily basis, it may take your body some adjusting to, so we recommend you take your Crushed Tonic with food!

During pregnancy
Taking collagen supplements can be helpful during pregnancy and postpartum. Pregnant or breastfeeding women can experience brittle hair and even hair loss, so collagen can help restore hair back to health. As the baby grows, more and more pressure is put on your joints. Collagen peptides promote joint health by helping to repair joint matrix degeneration and improve long-term joint comfort and mobility, as well as helping to restore bone mineral density and support healthy bone metabolism. There’s a LOT of stress put on our joints as we carry the weight of growing baby.

During breastfeeding
The postpartum benefits of taking collagen can help with skin elasticity by helping to tighten back loosened skin on the stomach, and preventing stretch marks and hairloss. During breastfeeding, women are at risk of bone resorption; therefore, a daily collagen supplement may in turn reduce a woman's risk of osteoporosis later in life.

Yes! Collagen can help in the fight against cellulite by strengthening connective tissues of the skin, and making your skin plumper and therefore less dimpled. Cellulite comes from many different things, but when your own collagen levels increase, your skin walls will strengthen and retain more moisture resulting in the skin which looks firmer and more hydrated. When your skin becomes firmer, and smoother, it reduces the appearance of cellulite lumps! I also recommend scrubs -- my favorite one is to mix apple cider vinegar, coffee beans, coconut oil, turmeric altogether (it might not look or smell so great) but it has SUCH softening and skin-turning properties!

Stretch marks are small scars that take place in the dermis, the tissue that lies just beneath the most superficial layers of skin. When scars form in the dermis, skin changes color and eventually softens. Drinking collagen helps with strengthening connective tissues of the skin, and because it helps your skin turn over, it gets rid of that extra, uppermost layer! When your skin becomes firmer, and smoother, it reduces the appearance of stretchmarks! I also recommend scrubs -- my favorite one is to mix apple cider vinegar, coffee beans, coconut oil, turmeric altogether (it might not look or smell so great) but it has SUCH softening and skin-turning properties!
