It is said that there are Korean and Chinese versions of the authentic Bio-Dance products, but in reality, "the Chinese version is not authentic." (See the attached Bio-Dance official announcement) ⭐️The buzzed-about pack is the Korean version⭐️ The cheap Chinese version is completely different. Although they are sold cheaply, the original price is extremely low. Since it is not authentic and is also cheap, it is unknown what ingredients are used. Please be careful not to be deceived by the low price and purchase the wrong product. ⭕️Important⭕️ ★★The surest way is to purchase from the official website!!★★ ⚠️ ★ Even if you purchase it from a store in Korea, it may not be genuine. (Counterfeit products purchased from Olive Young have been found) ★ The only sure way is to purchase from the official website. ⭐️How to identify (as of now), as taught by Bio-Dance official:⭐️ Check the position of the hyphen on the front label (see photo). ★Korean authentic version: BIO-COLLAGEN ★Fake Chinese version: BIO COLLAGEN- The expiration date and engraving change depending on the manufacturing date, so currently, be sure to check the position of the hyphen and purchase from the official website. ※ If the product you purchased is fake, be sure to contact the administration office (ask for contact information). The cheap Chinese version is... worth the price. ⭐️The size is small, thin, and the texture, feel, smell, and amount are all not good, and it is also easily torn and does not become transparent. Many people have been deceived and purchased products by being lured by the sales pitches of "authentic products," "trademark registration," "official channels," "lowest price," and "buzzed-about pack." ★ There is no authentic Chinese version with trademark registration. The Olive Young packs that advertise a large capacity are imitations because the capacity is different. You can also tell it's a fake from the position of the hyphen. There are also fake toner pads. Be sure to check with the official website before purchasing. This is a Korean version of the Bio-Dance Real Deep Mask Collagen Face Mask, 5 sheets, purchased from the official website in August. Simple packaging, anonymous shipping.
