The sperm bind through the corona radiata, a layer of follicle cells on the outside of the secondary oocyte. Fertilization occurs when the nucleus of both a sperm and an egg fuse to form a diploid cell, known as zygote. The successful fusion of gametes forms a new organism.
One of the most beneficial essential oils for skin care is geranium oil. This oil contains nutrients that help hydrate the skin, which is imperative for the regenerative process of skin cells. This oil is generally considered safe for sensitive skin, as well for those with frequent breakouts.
Essential oils are highly concentrated plant extracts (usually steam distilled) and are used in aromatherapy applications. The highly volatile essential oils offer therapeutic value and natural scent choices. For use in soap making, the scent does not last as long as a fragrance oil. Essential oils as a rule should be diluted before using on the skin. A patch test is always recommended before applying neat on the skin.
