How long do our cosmetics live for?
Which ones deteriorate the fastest and which have the longest validity period?
How do you know that a cosmetic is no longer usable when there is no information about the date of manufacture?
In the profession of make-up artist, this issue is of particular importance. We are responsible; not only for ourselves, but also for the client we paint.
The use of an expired cosmetic may cause serious infections for her eyes, which may result in conjunctivitis or eyelid infections.
Because of their delicacy, the eyes are more susceptible to infection than the rest of the face.
Therefore, we especially watch the expiry date of the mascara.
Its validity is short and ranges from 3-8 months. It is difficult to extend it because, when used, air gets inside the bottle, which causes the mascara to dry and crumble. That is why we pay special attention to our students so that they gain mascara with a gathering movement, not a pumping one. By pumping the brush, air is let in and the ink dries very quickly.
Old cosmetics that do not have direct eye contact also pose a danger.
Expired foundations, toners and concealers may cause a rash or allergy to appear on your face. Fluids have a short shelf life because they contain fat and water. Usually, white spots form on the edge of the bottle in which the primer is past its expiry date, which favors the growth of numerous bacteria.
We usually use creams and balms for 6 months from the time of opening.
Lipsticks can serve us for 2 years. However, if you notice that the lipstick is too soft or lumps have started to form on it, it is a sign that the cosmetic should be discarded.
Expired lipsticks can expose you to herpes.
The most durable are loose cosmetics: eye shadows, powders, blushes. If water does not get into them, they can last for about 18 months. However, remember to store these products properly.
They should be in a dry place and not exposed to light.
Signals that should bother us are:
– heterogeneous consistency,
– stratification of ingredients,
– bad smell,
– color change.
