RIN is Korean inner beauty for the part of skincare that doesn’t go on your face. We make formulas with actives chosen together, smarter ways in and formats you’ll actually want to keep taking.

In Korea, beauty has long included what goes in as well as what goes on. Inner beauty gives skin-supporting formulas the same attention as anything on your bathroom shelf, from the ingredients and how they’re delivered to the flavour and texture. Because even a great formula has to be one you’ll want again tomorrow.

We look at the whole product, not just the ingredient with the biggest name. What goes in, how it’s delivered and whether you’ll still want the next one. The lead active gets backup, the format does real work and taste isn’t left until the end as a rescue mission.

Because format is part of the formula. Glow Strips melt in your mouth, where absorption can begin. Collagen+ Jelly Sticks turn a daily serving of collagen into something you can tear open and chew.

Yes. They’re food supplements designed to be taken daily. We just don’t think that means they have to arrive as a pill, a powder or another tub asking quite a lot of your morning.

Our products are formulated and made in Korea, where inner beauty has had a proper place in beauty for decades.

No. Keep the serum. RIN is the inside step for the skin you’re already caring for. Not all skincare goes on your face.

Glow Strips support skin radiance, a more even-looking complexion and everyday antioxidant support.

Collagen+ Jelly Sticks bring daily collagen support, with hyaluronic acid, elastin, vitamin C and biotin for skin and hair.

Take one Glow Strip, one Collagen+ Jelly Stick or both together. You can also take up to two a day if you’d like to see results sooner.

Whenever you’re most likely to remember. Morning, afternoon or halfway out of the door all count. The time matters less than taking it each day.

Neither format needs water. Glow Strips melt in your mouth. Squeeze Collagen+ Jelly Sticks straight from the stick, then chew and swallow.

Speak to a healthcare professional before taking any food supplement while pregnant, breastfeeding, taking medication or managing a health condition. Take the ingredient list with you. It saves guessing.

No. Glow Strips and Collagen+ Jelly Sticks contain marine collagen from fish.

Both products contain fish. You’ll find the full ingredients and allergen information on each product page and pack.

Keep your products somewhere cool and dry, away from direct sunlight. Leave each strip or stick sealed until you’re ready to take it.

We aim to dispatch orders within one to two working days. Orders placed over the weekend or on a bank holiday will start moving on the next working day.

Standard tracked delivery usually takes two to three working days after dispatch. During particularly busy periods, it may take a little longer.

Standard UK delivery is £3.99. It's free when you subscribe or spend over £50

Yes. We’ll email you a tracking link as soon as your order leaves us. It can take a little while for the carrier to register the first scan, so don’t panic if it initially appears to be sitting very still.

At launch, we only deliver within the UK. Join our mailing list for news on where RIN is going next.

Contact us as soon as possible. We’ll do our best to catch it before the warehouse does, but once we've processed or dispatched an order, we may not be able to change it.

You can return unopened products within 14 days of delivery. Because RIN products are ingestible, we can’t accept opened packs unless the product is faulty or damaged.

Contact hello@rinskin.com before sending anything back so we can give you the correct return details. Return postage is your responsibility unless something went wrong on our end.

Not the unboxing we had in mind. Email hello@rinskin.com with your order number and a photo of what arrived. We’ll arrange a replacement or refund as quickly as possible.

Check your tracking link first. If it’s more than two working days past the expected delivery window, email hello@rinskin.com with your order number and we’ll look into it.
