Pigments and Dyes on Sale: What 12M After Opening Really Means When an artist sees a pigment or dye on sale, a natural question appears: can this product still be used professionally, or is it already close to expiring? The answer depends not only on the date printed on the packaging, but also on the period after opening mark — for example, 12M.This mark shows how long the product can be used after the bottle has been opened for the first time. For example, if an artist opens a pigment or dye on 22.10.2026 and the packaging shows 12M, the estimated period after opening is until 22.10.2027. However, there is one important rule: if the general expiry date comes earlier, that earlier date should be followed.So, a product being on sale does not automatically mean it is unsuitable for work. The main thing is to read the label correctly, check the general shelf life and follow proper storage rules after opening.Why pigments and dyes may be on saleA sale does not always mean that a product is “bad” or cannot be used. Stores may discount products for many reasons: assortment updates, packaging changes, seasonal offers, remaining stock of certain shades or special promotions for artists.For an artist, this can be a good opportunity to buy a needed shade at a better price. This is especially practical when it is a pigment or dye that is used often and will not sit unused for a long time.Before buying, however, it is important to look not only at the price, but also at the label: expiry date, package condition and period after opening.What does 12M after opening mean?The 12M mark means that after the first opening, the product is recommended to be used within 12 months. The letter M stands for months.This information is usually shown next to the open jar symbol. The marking is called PAO — Period After Opening.Simple examples:6M — use within 6 months after opening.12M — use within 12 months after opening.24M — use within 24 months after opening.For an artist, this is a useful guide that helps organize working stock and avoid confusion with opened bottles.How to store pigments and dyes after openingTo keep the product suitable for use during the stated period after opening, correct storage is important.Basic rules:close the bottle tightly after every use;do not leave the product open during a procedure;store it in a dry, cool place;keep it away from direct sunlight;do not store it near radiators, lamps or other heat sources;do not touch the bottle nozzle with hands or tools;do not mix products directly inside the bottle;do not pour leftovers back into the bottle.For pigments and dyes, hygiene matters. Even a valid product can become unsuitable earlier if it is opened, stored or used incorrectly.Why this matters for professional artistsAn artist often has not just one bottle, but a full palette of shades. Some are used every day, while others are used less often. Without tracking, it is easy to forget when a specific product was opened.That is why the 12M mark helps not only to know the time limit, but also to organize the workstation. The artist can plan purchases, use shades in the right order and avoid collecting too many opened products.This is especially relevant for permanent makeup, brow tinting, lash and brow procedures, where cleanliness, material stability and attention to detail are important.Is it worth buying pigments and dyes on sale?Yes, if the product has a valid expiry date, intact packaging, correct labeling and a clear period after opening. A sale can be a good opportunity to buy the needed material at a better price.However, the artist should honestly evaluate whether the product will be used in time. If it is a popular shade that is needed regularly, the purchase may be very practical. If it is a rare color used only once every few months, it is worth considering whether the opened bottle will simply sit unused.A smart purchase is not only about a good price, but also about understanding how quickly the product will be used after opening.Pigments and dyes at TatushechkaAt Tatushechka, artists can find pigments, dyes and other professional supplies for permanent makeup, brows, lashes and tattoo work.Before buying and using any product, it is important to check the information on the packaging: general expiry date, storage conditions and period after opening.
