I make the herbal infused oils by placing medicinal herbs in a large glass jar. I add sunflower vegetable oil (first cold pressure) and put them under the sun of Provence and directly on the ground of the mountains for 3 weeks to 1 month. I finally filter them several times until I finish with a very fine filter. The calendula solar infused oil can be used pure or as a basis for synergy with essential oils. The skincare products are made in Provence and in small batches with beautiful and simple ingredients. The raw materials are 100% french, natural and organic (Nature & Progrès french certification). - COSMETIC PROPERTIES - The herbal infused oil of calendula (which I make by myself) is anti-inflammatory, antioxidant and cicatrizing. - ORGANIC INGREDIENTS - Helianthus annuus seed oil, Calendula officinalis flower extract.
