This page explains how we put Opeau guides together, so you can judge how much weight to give them.
1. Celebrity claims need a public source
We only write that a celebrity uses a product when they have said so publicly. That means an interview, their own video or social post (for example a Vogue “Beauty Secrets” video or a magazine interview), or an official brand announcement. Every such claim links to its source and gives the year. Routines change, so a product someone named in 2022 may not be what they use today. We never invent or “tidy up” quotes. We only quote words that appear in the source, and otherwise we paraphrase.
2. Paid relationships are labeled
If a celebrity is a paid brand ambassador, founder or co-owner, we say so next to the product. Those mentions are marketing, not independent recommendations.
3. Prices are checked and dated
We list a typical US price from the brand or a major retailer and say when we checked it. Prices change often, so always check before you buy. We don’t quote Amazon prices in our articles.
4. How we pick dupes
A “dupe” on Opeau is a cheaper alternative with a similar purpose, similar key ingredients or a similar scent profile. It’s never an identical formula. We explain why each one made the list.
5. Researched from published sources
Unless an article clearly says otherwise, we haven’t used the products we cover ourselves. We compare published ingredient lists, specs, regulator records (such as FDA 510(k) clearances for devices) and credible reviews. Our hands-on experience is with at-home IPL, because we used to run an IPL device brand.
6. Health and devices
We avoid treat, cure and “clinically proven” language unless we’re quoting a regulator or a cited study. Our content is general information, not medical advice. Talk to a qualified professional about skin conditions, pregnancy, medications or device safety.
7. Corrections
Found an error or an out-of-date source? Tell us and we’ll review it and update the page, including the “last updated” date.
