Saggy skin develops as our bodies gradually produce less collagen. The decline in collagen happens over the course of a lifetime but becomes much more rapid after age 30. Other causes of skin laxity include losing a lot of weight quickly and exposing your skin to sunlight without protection. Similarly, environmental irritants and genetic factors also play a role in how quickly we age. At Lake Medical Spa we have several treatment options if saggy skin is a concern to you.
