Skincare is usually dismissed as a vain pursuit, undermining its connection to everyone’s health and safety. However, a study on skin chemistry and its microbiome revealed that skincare products can alter the dynamic and structures of molecules and bacteria on the skin. Furthermore, it was discovered that one’s health and lifestyle habits also shape the microbial composition of their skin.

These changes can affect your skin’s susceptibility to diseases and aging, so it’s important to pay attention to how products affect your skin’s health. If you want healthy skin, here’s how you can create a science-based personalized skincare regimen.

Keep your skin balanced by understanding its natural pH levels

The first step to creating a science-based and personalized skincare routine is understanding your skin’s natural pH levels. Different parts of your body have varying pH levels since they are primarily composed of water. While blood is normally slightly basic with a pH range of 7.35 to 7.45, the skin is naturally quite acidic with pH levels ranging between 4.2 and 5.6. The skin's acidic composition is very important in maintaining your skin’s barrier function and microbiome composition. Unfortunately, high-pH products, like bar soaps, can affect your skin’s structure. This then leaves it vulnerable to acne-causing bacteria, environmental irritation, and even dehydration. To protect your skin’s natural barriers, apply products within your natural pH levels. This ensures that your skincare products won’t disrupt the natural molecules that promote skin health.

Assess the connection between your health and your skin

You can also personalize your skincare routine based on science by assessing your overall health. Dr. Bruce Brod from the University of Pennsylvania stated that a physician specializing in dermatology can tell a lot about someone’s lifestyle and health by taking a look at their skin. Recognizing that the skin’s appearance can be caused by underlying medical conditions, Dr. Brod stated that dermatologists are trained to determine when to do a blood test and examine a patient’s medical history. To assess your overall health, consult a professional trained in healthcare studies. A general background in healthcare allows professionals to gain skills and competencies in physiology, health promotion, and disease prevention. This training teaches healthcare professionals how to recommend skincare products and lifestyle practices, based on their diagnosis. All in all, tapping into medical experts for skin health is a great way to get science-backed insights for your routine.

Consider the weather and season before choosing products

Aside from looking into internal factors like pH levels and health, you also need to consider how your external environment can affect your skin. Case in point: our article on the change in weather highlights that a shift in humidity, UV exposure, and temperature can affect the state of your skin. Once humidity drops and the heat increases, your skin will become more dry and dehydrated. This can even lead to inflammation and irritation, especially if you weren’t able to adjust your skincare routine beforehand. To illustrate, you can protect your skin in warm and humid conditions by applying a light, water-based moisturizer to prevent dehydration. Meanwhile, those in cold and dry environments will need thick creamy moisturizers to lock in skin moisture.

Understand the chemical composition of skincare products

Finally, you can personalize your skincare regimen based on science by understanding the composition of your products. This may seem overwhelming at first, but having a basic understanding of skincare ingredients can help you understand how certain products can work. This helps you gauge whether they can target your specific skin concerns or not. So when you’re assessing a certain skincare product, you need to look at the ingredients listed from the highest or lowest concentration. The first few ingredients in a product are usually the most potent, so take the time to research if the ingredients at the top are beneficial or harmful for your skin. You also need to be on the lookout for potentially irritating ingredients, like alcohol and fragrances, to avoid unwanted effects.


You can create a more personalized skincare regimen by understanding the science behind your skin as well as your skincare products. As such, you need to maintain your skin's natural pH levels, assess your overall health, consider your external environment, and understand the chemical composition of your products to achieve optimal results. With a science-backed routine, you're sure to see positive results.
