The severity of your issue depends on how often your skin is prone to redness.
Once in awhile, occasional redness is a temporary result of your skin care product. This redness can be countered with the right skin care products. If facial redness is your constant companion along with zits and irritation, we recommend you to consult a dermatologist.
In case of regular redness, it can be mistaken for acne, rash and other skin issues, when in reality the issue maybe Rosacea- a very common skin disease in which the redness can spread beyond the nose and cheeks due to weather changes, exercise or alcohol consumption.
