Skincare Formulation Framework-The Seven Formula Systems
With so many skincare products on the market, it can be overwhelming to know which one to choose.
The real difference between skincare products boils down to their formulations!
Today, I’ll give you a brief overview to help you understand the key ingredients in your skincare products.
Antioxidant System
The antioxidant system in skincare products prevents the oxidation and degradation of certain ingredients, primarily oils rich in unsaturated fatty acids.
Emulsification System
Normally, water and oil don’t mix, so to stabilize them, a "third party" is needed—something that bonds with both water and oil, which is the emulsifier. Our skin can often lack both water and oil, and this is where emulsifiers play a crucial role in stabilizing the formula. Depending on the type of emulsification system, the stability and texture of the skincare product can vary. Generally, water-in-oil formulas are more moisturizing, while oil-in-water formulas feel lighter.
If the emulsifier can’t hold the water and oil together for long, the product may separate, which is a common issue known as layering. In such cases, we rely on the second system.
Thickening System
Thickeners reduce the flow of the emulsification system, ensuring the stability of the entire formula. A good thickening system can significantly delay separation and improve the texture of the product.
Preservative System
This system mainly inhibits the growth of microorganisms in the skincare product, extending its effectiveness.
Efficacy System
This encompasses a variety of benefits such as brightening, anti-aging, acne treatment, and hydration. The efficacy system consists of one or more active ingredients that target specific skin concerns. The core is to identify the issue and, based on its causes, offer a solution.
Safety Assurance System
Due to changes in climate, environment, and the growing variety of skincare products, more people have sensitive skin. To minimize irritation for those with sensitive or fragile skin, the "safety assurance system" was developed!
Epidemiological data shows that apart from environmental factors, improper skincare use is a major cause of sensitive skin. To address this, soothing ingredients like dipotassium glycyrrhizinate and bisabolol are often added to reduce skin sensitivity.
Sensory Modification System
Colorants provide consumers with more imaginative possibilities through specific colors.
For example, Clinique’s “Dramatically Different Moisturizing Lotion” is known for its signature yellow tint, which leads consumers to associate it with "yellow oil"—thanks to the colorants!
Another key part is fragrance. Although national regulations clearly limit the types and amounts of fragrance allowed, it’s still recommended that people with sensitive skin avoid highly fragranced skincare products, as they may trigger allergies. Those with healthy skin don’t need to worry too much.
