Natural beauty from inside out

Our skin, along with our hair and nails, is often the first thing people notice about us when they look at us.

Next to its appearance, the skin also has a lot of important functions for our body, including:

● Protection: it provides a protective barrier against harmful bacteria and UV-light from the sun 

● Sensation: it acts as a sensory organ for you to experience touch, warmth, or cold

● Regulation: it helps keeping your body temperature at the correct level  

Our skin is composed of two main layers:

The epidermis is the outermost layer of our skin, protecting us from ultraviolet radiation, harmful chemicals, and infections. 

The dermis is the second, much thicker second layer of skin. This is where you will find collagen. Collagen fibers in the dermis provide the infrastructure for elastin, which maintains our skin’s elasticity, and enables hyaluronic acid to trap moisture. Aging takes place here before being visible on the surface.

As we age, the quantity and quality of collagen in our bodies decrease leading to: 



  • Reduced skin hydration 
  • Reduced elasticity and firmness 
  • Visual signs of aging, including wrinkles and pores 
  • Weakening of hair fibers, making them brittle and giving them a less radiant appearance

Beautiful skin and hair need a healthy foundation

Laugh lines can look and sound delightful, at the same time, reducing those wrinkles along with dry skin and fuzzy hair can help us feel young and vibrant.
