According to Mary Kay inventors, sensitive skin has a tendency toward dryness or flaking and flushing, reddening or blushing (i.e., erythema) when exposed to stimuli such as UV light, heat, cold, chemicals or even active ingredients in skin formulas.
Indeed, some actives known to cause erythema in sensitive skin are used to treat fine lines and wrinkles, sagging skin, acne, etc. As such, individuals affected by sensitive skin either must avoid such products or apply products that can help to alleviate these symptoms.
This invention relates to a combination of ingredients that can be used to treat or prevent erythema (i.e., reddened/flushed skin) in sensitive skin. This combination can be included in a wide range of product formulations, such as toners, gels, masks, etc.
