Is your skincare routine actually working—or just sitting on the surface? Many of the products we see in supermarkets and department stores promise glowing, youthful skin. But are they really powerful enough to deliver results?

Medical-grade vs over the counter skin care: What’s the difference?
As a professional aesthetician with over 20 years of experience, I’m often asked:
“What’s the difference between medical-grade skincare brands like Janssen Cosmetics and retail skincare brands such as Olay or No 7?”
At first glance, they may look similar. Both promise healthy, radiant skin. But when it comes to ingredients, results, and long-term skin health, the difference between professional and retail skincare is significant.
1. Ingredient concentration
Professional skincare products (like Janssen Cosmetics) contain higher levels of active ingredients—such as hyaluronic acid, peptides, retinol, and antioxidants. These actives are clinically formulated to penetrate deeper into the skin and create real, visible change.
Retail skincare brands (such as Olay skincare) must be safe for mass use, so the actives are present in lower concentrations. This makes them gentler but often less effective for correcting specific skin concerns.
2. Targeted vs general formulations
Professional skincare lines are treatment-driven. They are designed to address specific issues such as acne, pigmentation, dehydration, or ageing. They also complement in-clinic treatments for faster, longer-lasting results.
Retail products are more generalised, focusing on broad categories like “dry skin” or “sensitive skin.” While they can maintain hydration and comfort, they are not usually targeted enough to treat complex skin conditions.
3. Advanced delivery systems
Professional products use advanced delivery systems to ensure ingredients reach the layers of skin where they can have the most impact. This includes encapsulation, time-release technology, and pH-balanced systems.
Retail skincare tends to prioritise texture, fragrance, and packaging appeal. While enjoyable to use, these products may not always deliver actives effectively into the skin.
4. Expert guidance & safety
One of the greatest benefits of professional skincare is the guidance of a trained skin specialist. As an aesthetician, I assess your skin and recommend exactly what you need, ensuring safe use of potent products.
Retail skincare is designed to be used without professional advice. This makes it safe for general use, but it also limits the strength and effectiveness of the products.
5. Price vs value
Professional skincare often comes with a higher price tag—but this reflects:
Premium ingredient quality
Smaller, fresher production batches
Clinical research behind formulations
Personalised recommendations from professionals
Retail skincare is more affordable and widely accessible, but the lower cost often means less impact on long-term skin health.
Final thoughts: Investing in your skin
Both professional and retail skincare products have their place. Retail skincare is perfect for basic maintenance, while professional skincare offers transformative results when guided by an expert.
If your goal is to maintain comfort and hydration, retail brands can work well. But if you want to target specific issues and see long-lasting improvements, investing in professional skincare like Janssen Cosmetics is the way forward.

Hyperpigmentation in Winter
Many clients are surprised when their pigmentation suddenly appears darker during the winter months. Even though we associate pigmentation with summer sun, it is often far more noticeable once the weather turns colder. At Skinportant Clinic, we see this every year, and there are several reasons why it happens. Understanding these reasons can also help you manage and reduce pigmentation more effectively.
Does Wearing Foundation Every Day Damage Your Skin Barrier?
Wearing foundation every day can put stress on your skin — not just because of the silicones and chemicals in the product, but because foundation creates a film that stops the skin from breathing freely. The biggest issue, however, is the daily removal. Taking foundation off every single night requires stronger cleansers, more friction and repeated stripping of the skin’s natural oils, which can weaken the skin barrier over time.
Skin Purging: What It Really Means & Why It’s Nothing to Fear
Skin purging is a normal, temporary reaction that can happen when active ingredients or advanced treatments speed up cell turnover, bringing underlying congestion to the surface. It typically lasts 1-3 weeks and often appears in areas where you already break out.
The rise of K-beauty has led many to believe that all Korean skincare is superior — but with over 4,500 cosmetic manufacturers in South Korea, quality varies greatly. At Skinportant Clinic, we’ve seen clients with damaged barrier layers from 10-step routines and constant product layering. While some Korean brands produce excellent products, assuming all K-skincare is as effective or safe as regulated European formulas is misleading. True skin health comes from evidence-based formulations, ingredient integrity, and simplicity — not the country on the label.
