A Skincare Checklist Before You Buy
Before buying, check five things: what specific gap you're solving, whether a current product already covers it, whether the new item would replace or duplicate something, whether it maps to a priority you actually have right now, and whether you could confirm coverage without spending anything.

Why check before you buy
Marketing does not know what you have saved in your routine. Reviewing that list can inform a buying decision, but it cannot establish product suitability or replace product research.
The checklist
- What specific gap am I trying to solve? Name it precisely, not as a general wish for better skin.
- Does something I already own cover that role? Check honestly, not optimistically.
- Would this replace a step, or just add another layer on top? Replacing something can be worth it; adding on top of full coverage rarely is.
- Does this map to a priority I actually have right now? A product aimed at a concern that isn't currently relevant is easy to postpone.
- Could I confirm the gap without spending anything first? Checking your routine costs nothing; buying does.
If the checklist comes back clear
If a category is already registered, you have confirmed a fact about the saved list. That does not establish whether a concern is addressed. You can still choose not to buy; a purchase is not required to complete the check.
If a real gap remains
An unlisted category is not proof that you need a product. Consider what you want to change and review product information separately. Routine Check does not guarantee suitability or effects.
Frequently asked questions
Should I run this checklist for every purchase, even small ones?
It takes little effort and mostly prevents adding things that duplicate what you already have, so it's reasonable to use it as a habit, however small the purchase.
What if I don't know what's actually in my current routine?
My Routine holds the products you save, so keep it up to date yourself. It does not verify actual use. Routine Check checks whether a saved category is listed, not whether products address a priority.
Can this checklist replace advice from a dermatologist?
No — it's a purchasing checklist about routine coverage, not medical guidance. Skin conditions or reactions are a separate question for a dermatologist.
Run the checklist against your real routine
Start with a photo and a suggested priority, then separately review saved categories. Routine Check does not evaluate products against Today's Priority or determine a purchase need.
