Will old cosmetics have an adverse effect on my skin?

Cosmetics’ quality can only be maintained if they are properly stored and used.
A sealed product contains no fungus or bacteria.
Once unsealed, cosmetics may become exposed to germs through use or handling with unwashed fingers, or by being left open in bathrooms or on vanity units.
This may lead to contamination with mold or bacteria, which may cause the product to deteriorate or emit unusual odors.
In this way, old cosmetics may lead to skin issues.

Even if a product is not contaminated with mold or bacteria, it may still deteriorate if exposed to excessive heat, moisture, or direct sunlight. If a product is discolored or otherwise looks different, or if it smells different than when first unsealed, it may have deteriorated in quality. Please avoid using the product in such circumstances.
