Keep your skin young by using the right products.

Our house brand Sirène consists of a range of products that are made in a Belgian lab and that are suitable for most skin types. Skin ageing begins sooner than you think. As early as your late twenties, early thirties, your natural collagen production – collagen is what gives your skin its firmness – starts to decrease. Lifestyle is also an important factor. For instance, make sure to always protect your skin from the sun, even in winter. And besides the sun, smoking, caffeine and alcohol consumption all have a negative impact on your skin.
In your forties, your skin becomes thinner and drier, and from your fifties, your skin barrier starts to lose its strength and it becomes more sensitive. So, make sure to adapt your skin regime as you age, ask advice from your beauty therapist and take extra good care of your skin by regularly booking a professional facial treatment.
Prefer to do your own skincare at home? Our advice? Always cleanse your skin properly and add a serum to your daily beauty regime products. Our boost serum has a lifting effect and slows down the damage caused by free radicals. Our snail serum is packed with allantoins that protect the skin and promote the production of new skin cells.
