It is now the time to add a new layer of lipstick and for this operation I recommend using a lip brush for more precise application. Repeat the tissue stage and then apply a brand-new layer of lipstick and you can rest assured that your lipstick will last for the whole day.
Here are my general guidelines for the average shelf life of most cosmetics: Powder based products (e.g. mineral foundation, eye shadows, blushes): 2-3 years. Liquid foundation: up to 1 year. Lipstick/gloss/liner: 2 years max for lipstick. Shelf life can be extended by refrigerating. Lip gloss with a wand applicator may have a shorter shelf life. Lip liner 1 to 2 years.
