regimenlab.eu website review

13 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.3 s.

The page has 9,284 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 5.3 s on main-thread work while loading, 1.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Your mobile performance score is 62. Pages that score under 90 lose visitors before the first paint.

10 images could be 245 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 300 ms faster on a phone.

7 third-party services load with your homepage (Shopify, Klaviyo and shgcdn3.com and others), adding 1.2 MB and 377 ms of main-thread time.

About 59 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

6 long tasks block the main thread while loading, the longest for 298 ms. During a long task the page ignores taps.

Shopify costs a phone 171 ms of main-thread work and 838 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

Klaviyo costs a phone 137 ms of main-thread work and 314 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

About 209 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.

Polyfills for old browsers add 63 KiB JavaScript that modern phones do not need.

9 files are served with short cache lifetimes, so returning visitors download them again (57 KiB).

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

4 KiB could be saved by minifying CSS.

2 KiB JavaScript is shipped twice across bundles.

The page becomes fully interactive after 20.0 s. Good is under 3.8 s.

Your largest element takes 6.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “D BG Hero Banner Level Serum”.

Visually, the page fills in at 9.1 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 120 ms to 172 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Scripts block taps and scrolling for 285 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.2 s to 1.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.1 MB in 496 requests on a phone: images 1.4 MB (59), scripts 1.2 MB (250) and other files 855 KiB (129). Under 2 MB keeps phones on slow connections fast.

M_-_Circular_Highlight_-_Glycolide_Lipid_Repair.png is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

6 images further down the page (199 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.16 g of CO₂e: 139.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

19 tap targets are too small or too close together to hit reliably with a finger.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

31 visible links have no text or label, so screen readers cannot say where they go.

2 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

Your meta description is only 61 characters: “Regimen Lab is peer reviewed, scientifically-driven skincare.”. 70 to 160 characters is enough to sell the click.

2 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

The homepage links to 229 pages on regimenlab.eu and 26 external pages.

Your Organization JSON-LD is missing sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

https://regimenlab.com/collections/all, https://regimenlab.com/collections/kits, https://regimenlab.com/collections/serums, https://regimenlab.com/collections/moisturizers and https://regimenlab.com/blogs/labnotes use the same meta description. A description written for each page earns more clicks.

https://regimenlab.com/products/level-serum has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 29 found) and read each the way a search engine does.

13 of 27 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

1 image is served at too low a resolution for sharp phone screens.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 821 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 1 more (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 19 cookies (measured from a US location before any click).

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

Loading the homepage contacts 28 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
