Making Dermloagica 2x faster in 2 weeks

Dermalogica SA already had the brand, the products, and the traffic. Professional-grade skincare, a catalogue people trust, ads sending shoppers to PDPs.

The page was slow to show the product — and slow to become usable once it did. Main images lagged. Buttons appeared before they could be clicked. Shoppers who were ready to buy hit a stall.

The problem

LCP is when the largest thing on the page actually paints. On a Dermalogica PDP, that’s the product. If it arrives late, the page feels empty.

Revenue per visitor follows. A slow first paint and a laggy tap both sit on conversion — people bounce, or they tap something that isn’t ready yet.

That’s not a design problem. It’s a load-order problem.

What we changed

We didn’t redesign the store. We didn’t strip apps or rebuild the theme.

Three LCP-focused fixes:

• Got the main product image on screen first
• Cut work that was blocking the first paint
• Made the page interactive in step with what people could see

Same products. Same layout. The page just showed up — and responded — when it should.

The result

LCP came down 50%. Conversion rate lifted 8.89%. Revenue per visitor lifted 11.96%.

Zero new ad spend. Nothing else changed.

Identical site. Just much faster at first paint, and smoother when they tapped.

This is the pattern we see over and over: the revenue is already on the site. Speed is what stops it leaking at the weakest link.
