Best Beauty Brands to Shop in September 2026
This is the full list of beauty brands we currently track on GlowTrials. For each one you'll find what the brand sells, how many offers we have on file right now, and a direct link to its deals page.
We don't rank these by quality — we haven't tested every product from every brand, and pretending otherwise would be dishonest. What this page does is put them side by side so you can see who sells what before you start comparing prices.

How to use this list
Start from the brand closest to what you actually need rather than the one with the biggest discount. A large reduction on the wrong item is not a saving. Once you have a shortlist of two or three, compare the total at checkout — including delivery, and including any threshold you would need to hit for free shipping.
Offers change without notice. A code can be withdrawn, hit a usage limit, or expire on the same day it appears. If an offer on one of these pages doesn't apply at checkout, try another listing on that page rather than assuming the brand has stopped discounting.
Comparing brands properly
Once you have narrowed the list, the comparison that matters is not the headline price. Work through these in order:
- Does the brand ship to you, and at what cost? Several of the brands on this page are strongest in one region. Delivery charges and any import duty are added late and can reverse which option is cheapest.
- What is the total at checkout? Compare the final figure, after delivery and tax, rather than the number on the product page.
- What is the return window, and who pays to return? This is the detail that decides the real cost of getting it wrong, and it varies far more between brands than price does.
- Is the item actually in stock? A discount on a backordered item is not useful if you need it this month.
- Is there a minimum for free delivery? Adding a small item to cross the threshold sometimes costs less than paying for shipping — and sometimes costs more than it saves.
Where discounts usually come from
Across beauty retailers, offers tend to appear in a few predictable forms rather than at random:
- First-order and newsletter offers — the most common discount, and the one most reliably available if you have not bought from the brand before.
- Free delivery thresholds — effectively a discount if you were going to spend that much anyway.
- Seasonal and end-of-range clearance — the deepest reductions, but on whatever the retailer needs to move rather than what you want.
- Bundle pricing — genuine value when you need everything in the bundle, and a way of raising the order value when you do not.
None of these are guaranteed to be running at any given moment, which is why the brand pages linked above are worth checking before you order rather than assuming what you saw last month still applies.
What we list, and what we don't
GlowTrials collects publicly available offers and links straight through to the brand. We don't invent codes, and where an offer has no stated discount amount we list it as a deal rather than attaching a number to it. If you find a working code that isn't here, or one here that has stopped working, let us know through the relevant brand page.
