Why we're picky about products

In any large pharmacy in Cairo today, the shelves display hundreds of skincare products. Every product comes with a claim, every claim sounds scientific, every formulation appears unique. For an ordinary consumer, choosing one product among so many is harder than diagnosing a disease. The responsibility falls on the physician to filter this chaos and recommend what is genuinely worth using.

In our clinic, we only recommend products that have passed rigorous internal tests. The shelf patients see at the front desk is very short, perhaps only twelve products. This brevity is not scarcity. It is a deliberate decision.

What do we examine? First, the published evidence on the active ingredient itself. Are there peer-reviewed studies supporting the claims? Are those studies funded by independent bodies or by the manufacturer? How many patients were in the sample, and how long was the trial? These questions immediately exclude most products that rely on unpublished "in-house studies."

Second, concentration. The presence of an ingredient in the list does not mean it is present in an effective amount. Many products place niacinamide twentieth in the list, meaning at less than 1%, while proven efficacy begins at 4%. This is legally permissible deception but not ethical. We examine the ingredient's position in the list and any explicit disclosure of percentages.

Third, stability. Many active ingredients degrade quickly when exposed to light, air, or heat. Vitamin C, for example, loses potency in a transparent bottle within weeks. The packaging tells much about a brand's seriousness. A transparent bottle for a vitamin C product is an immediate disqualifier.

Fourth, simplicity. Products that combine ten "active ingredients" in one formulation usually contain none in effective concentration. A good product has one purpose and one main ingredient. Complex formulations are a marketing signal, not a scientific one.

Fifth, regional fit. Many luxury products come from European or Japanese brands, formulated for different skin types and climates. For most Egyptian patients, lighter, less occlusive formulations with higher photoprotection are more appropriate. We do not grant special status to a product simply because it is "European."

Sixth, value. A product at three thousand pounds per bottle may be less effective than one at three hundred pounds containing the same active ingredient at the same concentration. Price is not a proxy for quality. Often, price is only a proxy for marketing.

Seventh, tolerance. A product that irritates one in three users, however effective, is not a good product. We track our patients' reactions to every product we recommend and remove anything that causes recurring problems, regardless of what the research says.

What does this filtering produce? A short list of products we trust. A gentle cleanser, an essential moisturizer, a high-quality sunscreen, a calibrated retinol, a well-concentrated niacinamide. We do not recommend anything we would not use ourselves or recommend to our own families.

We say to our patients always: three good products used consistently are better than fifteen excellent products used occasionally. Products are tools. A good tool, used regularly and with understanding, gives results that exceed what seems possible. Many tools, by contrast, give confusion and frustration.
