What is Ethinylestradiol?
Ethinylestradiol is a potent, man-made form of the hormone oestrogen.

These combinations are designed to mimic natural hormonal cycles or suppress specific hormonal pathways, providing predictable outcomes for various reproductive and dermatological needs.

How does Ethinylestradiol work?
Ethinylestradiol works by suppressing ovulation and thickening cervical mucus to prevent fertilization. In the context of dermatological conditions like Acne, it lowers the production of androgens, which are hormones that can trigger excess oil production and skin inflammation. By stabilizing these hormonal fluctuations, it reduces the severity of skin concerns over time.
