iS Clinical Skincare: Debunking 7 Myths & Building a Clinical-Grade Routine
iS Clinical is a pioneer in science-driven skincare, loved by dermatologists and beauty editors alike. But even with a brand this reputable, skincare myths can still cloud your decisions. Let’s break down five of the biggest misconceptions — and show you how to build a results-driven routine with some of iS Clinical’s most iconic products.
Clinically Proven
Not tested on animals
1. Myth: “Tingling Means It's Bad for My Skin”
One of the most common concerns about high-performance products like iS Clinical Active Serum or other serums is the tingling sensation upon application. In reality, this feeling is completely normal and even expected. It's a sign that ingredients like glycolic acid, lactic acid, and salicylic acid are working to exfoliate and refine your skin texture.
Tip: Tingling usually subsides after a few uses. If you have sensitive skin, start by using the serum every other night and build up tolerance gradually.
2. Myth: “Serums Don’t Do Much Compared to Moisturizers”
This couldn’t be further from the truth. Serums are packed with potent active ingredients at higher concentrations. For instance:
- Active Serum, for instance, is clinically formulated to target breakouts, uneven tone, and signs of aging — all in one bottle.
- C-Eye serum targets dark circles, puffiness and finelines in the delicate area of the eyes, while brightening and firming.
Pro tip:
Apply serums before moisturizing for maximum absorption and efficacy. Follow our steps: Clean, Treat (serums), Hydrate & Protect
3. Myth: “You Don’t Need More Than One Product”
While a minimalist routine can work, strategic layering of products often yields the best results — especially with medical-grade skincare like iS Clinical. For example:
Formulated to target dark circles, puffiness, and fine lines around the delicate eye area. Vitamin C and peptides provide a brightening and firming boost.
For those ready to step into advanced age management, this next-gen retinol delivers results without compromising on skin comfort. Use at night after cleansing and follow with Moisturizing Complex.
This hydrating powerhouse strengthens your skin barrier, provides antioxidant protection, and locks in moisture after applying serums.

4. Myth: “Medical-Grade Means Harsh”
iS Clinical formulations are extensively tested for safety and tolerability, even for sensitive skin types. The brand combines botanical ingredients with pharmaceutical-grade actives, resulting in high-efficacy products that respect your skin barrier.
Key ingredients like centella asiatica, hyaluronic acid, and olive leaf extract offer calming and hydrating benefits alongside powerful actives.
5. Myth: “Results Take Months to Show”
While long-term consistency is crucial, many users report visible improvement in texture, brightness, and breakout reduction with Retinol + Emulsion 0.3 in as little as 7–10 days.
Clinical-grade products tend to deliver faster, more noticeable results when used correctly.
6. Myth: “Expensive Skincare Is Just Marketing”
While price doesn’t always equal quality, in the case of iS Clinical, you’re paying for clinical-grade ingredients, patented technology, and extensive dermatological testing. The Products undergo 10+ years of research and prestigious Universities in the USA.
Products like Poly-Vitamin Serum and Super Serum Advance+ undergo rigorous formulation and clinical trials, a far cry from standard over-the-counter options. They are parabeen free, alcohol free, fragrance free and are tested on humans not animals.
Plus, these high-performance products are often multitaskers, meaning you need fewer steps to achieve better results. There is a reason why they are multi award-winning products
7. Myth: “Sunscreen Is Only for Sunny Days”
UV radiation is present year-round, even when it’s cloudy or cold. Daily sunscreen use is one of the most effective ways to prevent premature aging, pigmentation, and the right sunscreen will hydrate and protect your skin.
Pro tip: iS Clinical’s
Extreme Protect offers broad-spectrum protection with a sheer, weightless finish — perfect for daily use, even under makeup.
