There are many sensitive skin conditions — acne, rosacea and contact dermatitis.
The skin tends to become more sensitive with age as it loses the protective moisture and fat that keeps it from drying out.
Sensitive skin is skin that is more reactive than usual. With sensitive skin, proper and gentle skin care is important, especially when choosing skin care products.
Also, the skin around the eyes is much thinner than the skin on the rest of your face, and as you get older, the tissues and muscles supporting your eyes weaken and may start to sag, so proper and gentle skin care is very important.
'Hypoallergenic' skin care products are not necessarily safer for sensitive skin. There are no government standards as to the use of the term 'hypoallergenic'. So it can mean whatever a particular company wants it to mean; and really is just a marketing word.
