The dermatologists’ guide to the dos and don’ts of mixing skin care products

Skin care is a personal and important aspect of many people’s lives. With the constant onslaught of new products and ingredients, it can be tempting to mix and match in order to achieve the perfect skincare routine. However, not all combinations of products and ingredients are created equal, and there are some important dos and don’ts to keep in mind when it comes to mixing skincare products.

The dos and don’ts of skin care mixing can be overwhelming to navigate, but it is crucial to understand the potential risks and benefits of different combinations in order to maximize the effectiveness of your skincare routine. According to dermatologists, there are several key factors to consider when it comes to mixing skincare products, including the order of application, potential ingredients interactions, and the overall impact on your skin’s health.


1. Do Patch Testing: Before mixing or layering new skincare products, it is important to patch test each product individually to ensure that it does not cause any irritation or allergic reactions. Apply a small amount of the product to a discreet area of your skin and wait 24-48 hours to observe any adverse reactions before incorporating it into your routine.

2. Do Research Ingredients: Understanding the potential interactions between different skincare ingredients can help you avoid any negative side effects. Certain ingredients, such as retinoids, exfoliating acids, and vitamin C, can have specific interactions when combined with others. It is important to thoroughly research each ingredient and consult with a dermatologist if you are unsure about potential interactions.

3. Do Layer Products in the Right Order: When layering skincare products, it is important to follow the general rule of applying products from thinnest to thickest consistency. This means starting with lightweight serums and essences before moving on to heavier creams and moisturizers. This allows each product to penetrate the skin effectively and maximize its benefits.

4. Do Use Sunscreen: Regardless of the skincare products you are using, it is essential to apply sunscreen every morning to protect your skin from harmful UV rays. This is especially important when using products that may increase skin sensitivity, such as exfoliating acids and retinoids.

5. Do Listen to Your Skin: Pay attention to how your skin reacts to different combinations of products. If you notice any irritation, inflammation, or breakouts, it may be a sign that a particular combination is not suitable for your skin. Trust your instincts and make adjustments to your routine accordingly.


1. Don’t Mix Incompatible Ingredients: Some skincare ingredients do not play well together and can cause adverse reactions when combined. For example, mixing retinoids with exfoliating acids can lead to increased skin sensitivity and irritation. It is important to research potential ingredient interactions and avoid combining products that are incompatible.

2. Don’t Over-Exfoliate: While exfoliating acids can be beneficial for improving skin texture and tone, over-exfoliating can lead to irritation and compromised skin barrier. It is important to be mindful of how often you are using exfoliating acids and to avoid using them in combination with other potentially irritating ingredients, such as retinoids.

3. Don’t Neglect Moisturization: Even when using active ingredients and treatments, it is crucial to maintain a well-hydrated skin barrier. Skipping moisturizer can lead to dryness and irritation, especially when using potent ingredients such as retinoids and exfoliating acids.

4. Don’t Assume All Natural Ingredients are Safe: While natural ingredients can be beneficial for the skin, they are not exempt from potential adverse reactions. Some natural ingredients can be sensitizing or irritating to the skin, so it is important to research and patch test them before incorporating them into your routine.

5. Don’t Rush Results: Skincare is a journey, and it takes time for products to show results. It is important to be patient and consistent with your routine, rather than constantly changing products or overloading your skin with active ingredients in search of quick results.

In conclusion, the dos and don’ts of skin care mixing are essential guidelines to follow when building an effective skincare routine. By patch testing products, understanding ingredient interactions, and being mindful of your skin’s needs, you can maximize the benefits of your skincare products while minimizing the risk of adverse reactions. It is important to consult with a dermatologist if you have any concerns about the products you are using and to listen to your skin’s feedback in order to achieve healthy and radiant skin.
