Products in general

Q:  I have heard that mineral oil is bad for the skin. Do Covermark products contain it?

Some Covermark products contain mineral oil.
Mineral oil is taken from underground mineral resources. Petroleum oil is a natural substance because it is made from organic matter that has decomposed underground over millions of years similar to charcoal and amber. In the 1970’s, impurities contained in low grade mineral oil caused skin problems. Today, mineral oil is a very safe raw ingredient since refining technology has become more advanced. The major mineral oil “petrolatum” is so safe that it is used in dermatologist clinics. Please feel safe about using products containing mineral oil.

Q: I have heard that UV absorbers are bad for the skin. Do Covermark products contain them?

Some Covermark products contain a UV absorber.
UV absorbers are often considered to be bad for the skin because they may induce an allergic reaction in people with allergic tendencies. However, UV absorbers cause no problem for people with no allergic tendencies. If you are worried about their negative influence or your skin is susceptible to irritation, consult a dermatologist.

Q: Do products with a high UV blocking value burden the skin?

UV blocking values (SPF, PA) and the level of burden on the skin are not proportional. Please feel safe about using products with a high UV blocking value. If you feel any unpleasant sensation using a product, stop using the product because it may not agree with your skin for some reason.

Q: Do covering foundations burden the skin?

Although some consider high-coverage foundations to inhibit skin respiration, it is not true. High-coverage foundations cause no problem as long as they are removed properly with an appropriate makeup remover. However, when a foundation is used on skin with acne, oil contained in the foundation may aggravate acne regardless to the level of coverage. Covermark recommends avoiding using foundation on skin with acne.

Q: Do products with oil accelerate suntan?

Oil increases sunlight permeability. Therefore, suntan is accelerated when wearing an oil-based cream. This is caused not only by oil contained in cosmetics but also by sebum. Use a sunscreen makeup base and foundation when going out in order to protect the skin from sunlight.

Q: Do cosmetics have expiration dates?

Cosmetics can be used safely for three years as long as they are unopened and kept under normal conditions (in a cool, dry place, away from direct sunlight).
According to the Pharmaceutical Law in Japan, an expiration date needs to be indicated on cosmetics that change nature within three years under normal storage conditions. Covermark products have no expiration date because they have passed various types of safety/stability tests so that they can be used safely for three years.

Q: Is it OK to use a cosmetic which was opened six months ago?

Yes, you can use it as long as the cap of the product has been tightly closed, the product has been stored away from high temperature/humidity and direct sunlight, and its odor remains unchanged. However, the product may have been contaminated if you have directly touched it with your fingers or hands. Make sure that there is no discoloration, separation, or muddiness before use and stop using the product if there are any abnormal signs.

Q: I do not plan to use a cosmetic product for a while. How should I store it?

It is not recommended to store opened cosmetics. When it is necessary, clean the opening of the container, tightly close the cap, and store the product in a cool, dry place away from direct sunlight.

Q: My regular cosmetic irritates the skin. What is wrong?

Even cosmetics you use for a long time can trigger problems when there is hormonal imbalance or stress.In case of itch or eczema, stop using the product and see a dermatologist.
