How we select products: our quality criteria

Hoe wij producten selecteren: onze kwaliteitscriteria Kenza Beauty Lab

At Kenza Beauty Lab, every product in our range is there for a reason. Behind each choice lies a careful selection process. But how exactly do we do that? And why won't you find cheap junk alongside quality top-performers here?

In this article, we'll take you behind the scenes of how we choose products.

Step 1: Scientific Basis

The first thing we look at is: does it really work? Not based on marketing claims or pretty packaging, but on evidence. We look for:

  • Clinical studies and peer-reviewed research
  • Approvals from dermatological or medical bodies
  • Proven active ingredients or technologies (such as 660nm and 850nm wavelengths in LED devices)
  • FDA approval or CE certification where applicable

If there's no scientific basis, we don't include the product — no matter how good it looks.

Step 2: Quality and Safety

A product must not only work, it must also be safe. We check:

  • Material safety — no harmful substances, skin-safe materials
  • Electrical safety for devices — CE certification, correct voltage and power
  • Ingredient lists for skincare products — no unnecessary irritants
  • Production standards and quality control

Step 3: Fair Price-Quality Ratio

We believe that quality doesn't always have to be expensive — but cheap is rarely good. We look for products that:

  • Have a fair price for what they deliver
  • Are durable and last a long time
  • Perform comparably or better than more expensive alternatives

We don't include products that are expensive only because of the brand name, nor do we include products that are so cheap that quality suffers.

Step 4: User Experience

A product should also be pleasant to use. We pay attention to:

  • Ease of use and clear instructions
  • Comfort for devices worn on the skin
  • Texture, scent, and application for skincare products
  • Consistency of results with regular use

Step 5: Fit with the Kenza Beauty Lab Brand

Finally: does the product fit who we are? Kenza Beauty Lab focuses on premium beauty and wellness — products worthy of a ritual. This means we consciously choose products that:

  • Fit a serious beauty and wellness experience
  • Meet the needs of our customers
  • Contribute to a complete routine, not just standalone gadgets
