Fake most often expensive import funds. The easiest way to identify fake is a detailed consideration of the packaging. Check fonts - they should be clear and smooth. Paints on the packaging, paper quality, liner quality - additional features for which counterfeit can be recognized, especially if you ever used a similar original product. Packaging of a cosmetic agent should not be easily opened for testing - there must be stickers or protective transparent films, showing that no one has violated the integrity of the packaging before you. All packaging should contain inscriptions in Russian or a sticker with a translation into Russian main composition, shelf life, instructions for use.
In my opinion, the most reliable way to distinguish the fake goods from the original is the accompanying documentation for the product. Any cosmetics must have a certificate of conformity. The following groups of goods are subject to mandatory certification: colognes and water fragrant and toilet; Essential perfumes and natural oils; Parafumeric and cosmetic kits; Cosmetic products; Soap toilet. If the selling side refuses to show you this kind of documentation - it is better to refrain from buying!
