Lipsticks are generally considered safe for use when used as intended. However, some lipsticks may contain ingredients that can be harmful if ingested in large amounts. For example, some lipsticks may contain heavy metals such as lead, which can be toxic if ingested in high quantities over a long period of time. Additionally, some people may have allergies or sensitivities to certain ingredients in lipsticks, which could cause skin irritation or other reactions. Overall, the risk of harm from using lipsticks is low for the average person. It is important to use lipsticks as directed, avoid ingesting them, and discontinue use if any adverse reactions occur. If you have concerns about the safety of a specific lipstick or its ingredients, you can consult with a healthcare professional or dermatologist for guidance. **

Yes, lipsticks can go bad over time. The shelf life of a lipstick is typically around 1-2 years, but this can vary depending on the ingredients and preservatives used. Signs that a lipstick has gone bad include changes in texture, smell, or color, as well as the presence of mold or an off-putting odor. It's important to regularly check your lipsticks for any signs of expiration and to replace them as needed to avoid any potential skin irritation or infection. **

Mac lipsticks are known for their long-lasting and highly pigmented formulas, which can make them more kiss-proof than some other lipsticks. However, the kiss-proof factor can also depend on the specific formula and finish of the Mac lipstick. For example, matte lipsticks tend to be more transfer-resistant and therefore more kiss-proof, while creamier or glossier finishes may transfer more easily. Overall, Mac lipsticks are generally considered to be long-wearing and have good staying power, but individual experiences may vary. **

Subtle MAC lipsticks are lip colors that provide a more natural and understated look. These lipsticks typically have a sheer or satin finish and come in shades that are closer to the natural color of the lips, such as nude, pink, or peach tones. They are designed to enhance the lips with a hint of color, rather than making a bold statement. Subtle MAC lipsticks are great for everyday wear and can complement a wide range of makeup looks. **

Liquid lipsticks that do not stick typically have a more lightweight and comfortable formula that does not dry down completely. Some examples of liquid lipsticks that do not stick are the Glossier Generation G Sheer Matte Lipstick, the YSL Tatouage Couture Liquid Matte Lip Stain, and the Fenty Beauty Gloss Bomb Universal Lip Luminizer. These products provide a more hydrating and glossy finish without the sticky feeling often associated with traditional liquid lipsticks. **
