You can tell the difference by looking at whether the content is identified with a hashtag like #sponsored or #ad. Honest reviews should include both the positives and negatives of a product, and the person speaking should be mindful of all skin and body types. Some beauty bloggers also disclose whether they got the item for free, or if theyre affiliated. And to get a complete picture of the product, its always better to get a holistic perspective from different sources.
