Shark Sauce

What it does: Fights dark spots, brightens skin tone, hydrates

Suitable for all skin types.

When it comes to fighting hyperpigmentation and brightening skin tone, the choices often seem stark. Fade dark spots with harsh, photosensitizing retinoids and exfoliants, or put our faith in brightening products that may or may not contain enough of their active ingredients to make a difference. It’s totally legal to list a proven ingredient but include it in an ineffectively low concentration. In most cases, you’d never know until you’ve been using something for ages and seeing no results.

Our flagship product Shark Sauce was born out of this frustration. This hydrating and brightening serum contains 5% niacinamide (Vitamin B3) and 3% n-acetylglucosamine, the optimal concentrations for these research-backed ingredients to work synergistically to fight hyperpigmentation. The sea kelp bioferment, the result of fermenting sea kelp with lactobacillus to break it down into smaller and more bioavailable compounds, smooths skin and traps moisture without heaviness, making Shark Sauce a great oil-free liquid moisturizer.

Shark Sauce is totally shark-free. Its name comes from a nickname of one of our muses, Fiddy Snails, for whom it was originally created.

How to use
Apply several drops to cleansed face after any actives and toners and before any creams. Follow with moisturizer. If using with other Holy Snails products, this should go on after Snowbang Essence and before El Dorado Oil Serum or Perseids Oil. This product does not contain any photosensitizing ingredients, but the most vital and effective anti-aging step in your routine will always be sunscreen. Please always use sunscreen in generous amounts for best results in fading hyperpigmentation and fighting visible skin aging.
Other Notes
This product is not intended to diagnose, treat, cure, or prevent disease. Always consult with your professional skin care provider. This does not contain sharks. This does contain parabens, as they are considered very safe and effective preservatives. It does not have any fragrances, and some people have reported a slight smell (due to the sodium lactate, which comes from sour milk - some people can smell it more strongly than others). Please always patch test any new products. Our products have very concentrated ingredients, so please patch test to make sure you do not have any sensitivities to any of them. This product does not cause purging, so if you experience breakouts or irritation, please discontinue use. There is a Sample/Travel Sized version to try if you are unsure of your ingredient sensitivities.

Permanent place in my routine

I have been using Shark Sauce since it came out, and I will continue to use it as long as it's available. Nothing beats it for efficacy, not even products three times the price. I'm in my mid 30s with very sensitive, acne-prone skin, and not only does Shark Sauce not break me out, it calms my reactivity overall so trying to add other products to my routine doesn't cause such terrible breakouts the way they did before I used this. When I skip Shark Sauce I notice my skin tone is not as bright or even, too. I recommend this product and Holy Snails in general to basically everyone who asks me where to get the best of the best.

Been using since it came out. It is a constant in my routine. Will always buy!


Lasts forever and keeps skin super moisturized


Too pricey


I don’t really consider myself a skincare person, but my friend who is said I should try this. I feel like it really helps my skin recover from a pimple and be brighter. I see a noticeable difference when I don’t use it for a few weeks. My routine is super minimal, just sunscreen in the morning and shark sauce + moisturizer at night.
