The Science of Healthy Skin

We believe that healthy skin is youthful skin, but more than that, the health of our skin can be a direct reflection of our overall health, so in that sense, it matters!

So what is healthy skin? Our skin is made up of three main layers. When all three layers are at their healthiest, they are able to perform their important functions.

The epidermis is the outermost layer, and a healthy epidermis is one that effectively keeps bad stuff from entering our bodies (think pollution, toxins, microorganisms, UV radiation etc) and good stuff from escaping (think moisture, vitamins, minerals). Maintaining the health of the skin’s barrier is important to prevent both infection and dryness.

The second layer - the dermis – is a complex combination of blood vessels, hair follicles and sebaceous (oil) glands. It plays a key role in cushioning your body and preventing premature aging, as it contains the collagen & elastin required for skin’s structure, plumpness and elasticity. As we age, this layer loses some of this structure, so maintaining the health of the dermis is key to prevent premature sagging, dryness or excessive wrinkling. Foods and skin products that help boost collagen and elastin can help maintain the health of the dermis.

The deepest layer, the hypodermis, is composed of fat and connective tissue that insulates your body and cushions internal organs. As the innermost layer of skin, it is made up of fat and connective tissues that house larger blood vessels and nerves. It acts as an insulator to help regulate body temperature and connects skin to muscles and bone. The hypodermis provides shaping and contouring, and is thickest in the abdomen and shoulders in males, and in the hips, thighs, and buttocks of females.

The Role of Hydration in healthy skin

Hydration is crucial for maintaining healthy skin, helping keep the skin plump, elastic, and free from dryness. When we're dehydrated, our skin can become tight, flaky, and open to infection. Drinking plenty of water and using good hydrating skincare products can help maintain the skin's hydration and health. 

Nutrition and Skin Health

A healthy diet has a direct impact on healthy skin. While healthy eating in general is important, there are certain foods that specifically impact skin health. A diet rich in antioxidants, vitamins A, C, and E, as well as omega-3 fatty acids, are particularly beneficial (ie leafy greens, berries, nuts, and fatty fish). These nutrients help to fight free radicals, reduce inflammation, and support collagen production. On the other hand, milk/dairy and sugar have been associated with acne and breakouts.

Sun Protection

Much of the degradation of our skin health is caused by excessive sun damage, especially in Australia. There are broadly two mechanisms by which the skin is protected from sun exposure – one is to block the sun’s damaging effect (think topical sunscreens), and the other, is to build your skin’s resistance to radiation. This can be achieved through diet as well as incorporating natural ingredients in skincare that boost your skin health. Red raspberry seed oil is one ingredient that has undergone some scientific research and is estimated to provide sun protection of around SPF 30-50. 

Skincare Routine

A consistent skincare routine which minimises exposure to toxins is an important tool in maintaining healthy skin. A good cleansing routine removes dirt, oil, pollution and makeup, prevents clogging and doesn’t strip your skin of its natural oils. A regular habit of exfoliating (2-3 times a week) effectively removes dead skin cells and promotes cell turnover (think glow!) as well as preventing cells from becoming clogged. Moisturising then becomes an important way to enhance the protective barrier, keeping the good stuff in and the bad stuff out.
