Add your products.
Watch it track itself.

Add each skincare product in about 30 seconds. Enter the name, brand, date you opened it, and the PAO number โ€” that's the months figure inside the little jar symbol on every product. Skinkarei calculates expiry dates instantly and color-codes your shelf.

๐ŸŸข

Common questions

Quick answers

What is a PAO date and where do I find it?
PAO stands for Period After Opening. It's the number inside the little open jar icon printed on most skincare products โ€” like "12M" meaning 12 months. It tells you how long the product is safe and effective after you first open it, not how long it sits unopened. If your product doesn't have one, a general rule is 6 months for serums, 12 months for moisturizers and cleansers.
Is Skinkarei really free?
Yes, completely free. Skinkarei earns small commissions when you shop products through the app's affiliate links โ€” at no extra cost to you. That commission is how we keep the app free for everyone. We will never charge for the core tracking and routine features.
Do I need to download an app?
No download required. Skinkarei runs entirely in your web browser on your phone, tablet, or computer. Just open the link and start adding products. If you want it on your home screen, you can use your browser's "Add to Home Screen" option for an app-like experience โ€” no app store needed.
How does the ZIP code weather feature work?
You enter your ZIP code when you create your account. Skinkarei uses a free public weather API to look up your local city's current temperature and conditions. There's no GPS access, no location permission popup, and no data stored beyond your ZIP. Each time you open the app it fetches today's weather and adjusts your routine recommendation automatically.
Is my data private?
Yes. Your shelf data is stored locally on your device โ€” not on a server. Your ZIP is only used to call a public weather API. Your email is used for newsletters only and is never sold or shared. Skinkarei earns through product affiliate links, not through selling your personal information.
What skincare brands and traditions does Skinkarei cover?
Skinkarei covers all skincare traditions with a deep focus on Asian beauty โ€” K-beauty (Korean), J-beauty (Japanese), C-beauty (Chinese), T-beauty (Taiwanese), and Thai skincare. Thai beauty has a rich tradition of its own, rooted in natural herbal ingredients like turmeric, tamarind, and jasmine rice โ€” distinct from Taiwanese T-beauty and increasingly recognized globally. Product recommendations currently include brands from Olive Young, Dermafirm, Soko Glam, and Amazon Beauty. We are actively seeking partnerships with Japanese, Chinese, Taiwanese, and Thai skincare brands.
Can I use Skinkarei for any skincare products, not just Asian brands?
Absolutely. The expiry tracker, routine guide, calendar reminders, and skin concern guide work with any skincare product from any brand or tradition. You can add CeraVe, La Roche-Posay, The Ordinary, or any product you use. The Asian skincare focus is in the curated shop recommendations โ€” the core app is for everyone.
