Don't Believe the Hypoallergenic Hype
Many people with sensitive skin automatically assume that a skin care product labeled "hypoallergenic" must contain fewer allergens than a product designed for normal skin.
According to the United States Food and Drug Administration (FDA), which regulates American cosmetics and pharmaceuticals, there are absolutely no criteria surrounding use of the term hypoallergenic [source: FDA]. It's purely a marketing buzzword.
So, just because a moisturizer is labeled hypoallergenic, don't go and slather it all over your face. At the very least, you should conduct your own patch test by applying a small amount of the product to the inside of your forearm. Look for adverse reactions before using it elsewhere.
