Frequently asked questions about our Serums & Oils products

We will be happy to answer them.

What types of facial serums are there?

There are different types of facial serums that specifically address different skin needs. These include moisturizing serums that provide intense hydration, anti-aging serums with active ingredients like bakuchiol or vitamin C for increased elasticity and radiance, and clarifying serums that combat impurities and inflammation. You can also find specially formulated serums for sensitive or mature skin that rely on natural active ingredients.

How do I apply a serum correctly?

Apply a serum after thorough cleansing and before your face cream. Use just a few drops and gently smooth the product onto your face, neck, and décolleté with your fingertips.

How long does a vitamin C serum last?

Vitamin C serum typically remains effective for about six to twelve months when stored away from light and air. Since vitamin C is sensitive to oxygen and light, dark packaging and cool storage protect the serum from premature degradation.

Who certifies natural cosmetics?

Natural cosmetics are certified by independent organizations such as NATRUE, COSMOS, and the BDIH (German Institute for International Trade in Food and Beverages). These bodies examine the ingredients, manufacturing methods, and sustainability criteria to ensure that the products meet strict ecological and ethical standards.
