The importance of skin diagnosis
Understanding your skin's specific needs
Every skin is unique and its condition can change depending on many factors: age, hormones, environment, stress, and even lifestyle. Understanding your skin type—normal, dry, oily, or combination—is essential, but you also need to consider its specific needs: dehydration, sensitivity, imperfections, or signs of aging. These needs can vary according to the seasons, stress, or hormonal changes. Every skin can react differently depending on the circumstances, even if its skin type remains the same. A precise skin analysis can determine the true physiological needs of your epidermis .


A ritual adapted to your skin priorities
A detailed skin analysis is essential to defining a fully tailored skincare routine. By identifying your skin's specific needs—whether it's strengthening the skin barrier of dry skin, rebalancing lipids in oily skin, or soothing sensitive skin—our dermatologist will propose a tailored skincare routine following your diagnosis. This approach maximizes the effectiveness of each treatment by precisely targeting your skin's needs, ensuring long-lasting and measurable results. Thanks to a well-defined skin typology, you'll benefit from perfectly tailored product recommendations.
Avoiding Common Care Mistakes
Many people use skincare products that are too aggressive, poorly targeted, or insufficiently hydrating, thinking they're doing the right thing. The result: imbalances, tightness, imperfections, and more. An expert skin diagnosis can help avoid these common mistakes. You can adopt a routine that respects your skin by choosing products tailored to your profile and specific concerns, preserving skin balance and preventing future problems.

How does our skin diagnosis work?
How does an online skin diagnosis work?
Our dermatologically-based skin diagnosis relies on a simple and quick-to-use tool. By answering a detailed questionnaire, we analyze all of your skin's characteristics: how it feels, clinical appearance, skincare habits, environmental factors, and specific concerns. This approach allows us to define precise skin profiles and identify your physiological priorities. Following the questionnaire, our dermatologist establishes a selection of customized products, guaranteeing a targeted response tailored to the real needs of your skin.
What is a skin diagnosis used for?
Our online skin diagnosis accurately assesses your skin's characteristics and specific concerns, such as acne, sensitivity, or loss of firmness. This analysis is essential for guiding your skincare choices and ensuring the best products are selected for your skin type. By personalizing your routine, the diagnosis maximizes skincare effectiveness and helps maintain long-lasting healthy skin, while optimizing visible results.
Is the diagnosis reliable without a physical consultation?
Our online diagnosis is based on a skin analysis designed by our dermatologist, allowing us to accurately identify skin types and their specific needs. This method provides a solid foundation for building a tailored skincare routine.
