Take care of the planet, take care of yourself

Certified marine cosmetics


The company works for all the young, dynamic women who dare to change the world. They are passionate, sports-lover, respectful to the environment, and conscious of the benefits of healthy nutrition and the use of certified natural cosmetics. They use organic, natural, cruelty-free and vegan products without parabens, dyes or petroleum derivatives.
The Dersia women share our values and are highly conscious of protecting the environment and aware of responsible consumption. We believe in taking care of the planet.

Dersia was born from her passion for the sea and the respect for nature’s resources. We aim to honestly take care of the beauty of eco-active women, and we adapt to her cosmopolitan and all-terrain lifestyle. 

Dersia is a certified natural cosmetics firm with BIO ingredients on its formulas. It is a young and accessible firm that explores the sea beds to create exceptionally and unique formulations that are rich in the best active ingredients and respectful with your skin.

 Dersia’s great effectiveness stems from the high concentration of Spirulina. Spirulina is a unicellular microalga capable of inhibiting the passage of time in your skin, and it is present in all our products. It delays skin ageing, reduces acne side effects in the skin, blurs spots, and prevents premature wrinkles. Dersia makes your skin look healthy, young and full of energy.

Dersia: the effective preventive and anti-ageing solution with a high concentration of active ingredients for young skins.

Regardless of age, ageing of the skin and the appearance of wrinkles is one of the biggest concerns of women. If we manage to keep the skin healthy and firm, we will preserve its youthful appearance for longer. Under this premise, Dersia explores the sea beds to create exceptionally unique formulations that are rich in the best active ingredients. Dersia’s great effectiveness stems from the high concentration of active ingredients and Spirulina. Spirulina is a unicellular-microalgae capable of inhibiting the passage of time in your skin, and it is present in all our products.


Laboratories Neoalgae is an expert in microalgae research. It has a highly specialized laboratory dedicated to the study of microscopic organism. Its highly qualified personnel cultivate and extract all the active ingredients from the Spirulina microalgae. Spirulina is a cyanobacterium that stands out for its high concentration in phycocyanin. Phycocyanin is a protein naturally present in the Spirulina with the highest antioxidant capacity that nature offers us.


Laboratories Neoalgae maximizes the concentration of phycocyanin by shading the crop at different times during the year. In doing so, we ensure that the Spirulina oils present in the entire products range of Dersia have an outstanding ratio and quality of phycocyanin, creating a product line of high quality certified natural cosmetics. We have become an advanced skincare specialist laboratory for the prevention and anti-ageing of the skin.
