There is no danger to your skin if women use products made for men, and vice versa. However, some products may not be suitable for one or the other.Test the product first to confirm that it is appropriate for your skin type.
Cosmetic products are made in accordance to preference, such as physiology of the skin, scalp or hair of men and women respectively. Some cosmetic products for men like skincare and hair growth tonic are made based on men's physiology and preferences because men's sebum level is higher than women's.
On the other hand, cosmetic products for women have more moisturizing texture than men's based on women's physiology and preference.

The features or effects of cosmetics depend on the product. Read instructions and warnings carefully for effective usage to avoid trouble.
The following are general notes to maintain the quality of cosmetic products.

• Use products only with clean hands, finger and tools
• Avoid directly touching the rim of any container with hand or cotton
• Close the container's lid or cap tightly after each use
• Do not put product contents back into the container once dispensed onto palm or cotton
• Once opened, continue using until empty
• When storing a product that has been opened, wip the rim of the container with a tissue and keep the lid or cap tightly closed
• Store away from direct sunlight
• Avoid storing in high temperature or high humidity

Fill the container up to about 80% capacity to avoid overfilling. Glass containers are recommended.
Fragrance products contain large amount of alcohol. If kept in high temperatures, the contents may expand and break the container. Filling products to the brim increases the likelihood of cracking or breakage. Be careful not to fill it over 80% of the container's capacity, as it may also cause spilling.

The foundation has hardened because the oil the powder has consolidated. Remove the hardened surface to continue use.
If the sponge or a puff was not clean, the powder foundation may have become stiff due to oil or particles from other cosmetics. Sponge or puff should be cleaned frequently.

Cosmetic products can protect the skin from external factors and keep it in good condition.
This does not mean that skin would revert back to its original condition and lose those benefits by stopping use of cosmetic products, but continuous use of cosmetics products can be beneficial.
Cosmetic products cannot change hereditary skin conditions, but they can help support homeostasis, which is the skin's natural power to maintain healthy functioning.
Though younger skin appears to recover quickly from damages, Shiseido research has discovered that damage accumulates inside the skin. The use of cosmetic products protects the skin from external aggressors such as UV rays, dryness or oxidization, and helps to reduce the effects of these damages.
The use of cosmetic products can protect skin long-term. For example, acne-prone or dry skin concerns can improve with the use of cosmetic products.
If you stop using cosmetic products for a prolonged period of time, skin would gradually revert back to its original condition.

This would not happen.
Skin naturally tries to maintain homeostasis, which is the skin's natural power to maintain healthy functioning. But external aggressors such as UV rays, dryness or oxidization, or internal aggressors such as aging and fatigue outweigh skin's natural power.
Skincare products aim to support skin's optimal condition, not take away its ability to produce radiance and beauty on its own. Use skincare products that are suited to your skin type to help support homeostasis power to keep the skin in good condition.

If you use a cosmetic product incorrectly, you cannot achieve its full effects.
For example, using less than the recommended amount of moisturizer may actually worsen skin dryness because not enough moisture is being provided to skin.
It is important to use cosmetic products according to the recommended usage instructions in order to achieve their full effect.

It is important to use products correctly as each has a different function. Most daytime skincare products are made to protect the skin from UV rays, as foundation would be applied after that and will improve makeup wear/application. At the same time, nighttime skincare products are formulated to improve skin conditions while sleeping and offer no UV protection.Therefore, we recommend checking the product containers and following the recommended use.

Using a cleansing foam without lathering may cause skin to become dry or rough.

<How to lather cleansing foam (tube type)>

1. 1. Wash your hands. Otherwise, cleanser will not foam.
2. 2. After lightly splashing face with water, take one centimeter of cleansing cream onto palm, and lather with a little lukewarm water until fluffy. Then, gently clean your face with the foam.

Skin-brightening products do not bleach skin, so skin will not become any more whitened than its original skin tone. However, continuous use of brightening products helps to make dark spots less visible and clarifies skin overall.
First, protecting skin from UV rays with SPF protection and using brightening products helps to reduce the visibility of dark spots and freckles, which can sunburn. Skin begins to look more clear.
Rough skin also looks duller. By providing enough moisture, skin becomes brighter with an overall look of clarity.

Use skincare products to prepare skin and then follow with makeup base or concealer to beautifully, cover up dark circles and make eye shadow colors look more vivid.
For dark circles that are less apparent, select a concealer that matches your skin. For dark circles that are more apparent, select a concealer shade that is inbetween your skin and the dark circles.
In order to prevent dark circles, it is important to get enough sleep and to improve blood circulation with facial massage. Creams, serums or masks that revitalize the eye area are also effective.
