Steroids, specifically progestin or a combination of progestin and estrogen, are commonly used in contraceptive skin patches as they can prevent ovulation and thicken cervical mucus, making it difficult for sperm to travel. Proteins and carbohydrates would not be suitable for absorption through the skin for contraceptive purposes, and substances dissolved in water may not be absorbed well enough to provide effective contraception.
