How to Properly Apply Basic Cosmetics, According to a Dermatologist
Hello, I am Dr. Sang-ju Lee, a dermatologist. How many cosmetic products do you use in your skincare routine? Many people, thinking 'it's good for my skin,' apply more products than necessary, and surprisingly, a significant number end up visiting the clinic due to skin problems. Today, I will explain how to properly use basic cosmetics.
Are You Applying Too Many Cosmetics?
Nowadays, many people use too many cosmetic products. Some individuals might use various basic cosmetics, thinking, 'My skin is sensitive, so I need to apply many different things.' However, applying too many different types of basic cosmetics can actually be harmful to your skin.
Why Do Dermatologists Use Only Two Products?
In my case, I typically use only two basic cosmetic products. The first is for cleansing, and the second is a moisturizer to hydrate the skin. There's a good reason for using just these two.
Cosmetics are made from various chemical substances. If you are constantly exposed to chemical substances that don't suit you, it can naturally cause skin problems. Just as allergies can develop from eating various foods, using too many different cosmetic products on your skin can increase the likelihood of developing allergies. Therefore, it is important to use a small amount of products that suit you, if possible.
It's Important to Understand the Purpose of Basic Cosmetics
What we commonly refer to as basic cosmetics each have a specific purpose. It's important to use them according to their intended purpose.
Our skin is healthiest when it is slightly acidic (around pH 5-6). Maintaining this pH prevents harmful bacteria from growing and strengthens the skin barrier. However, after washing, the skin tends to become alkaline. At this point, it's necessary to quickly restore the skin to a slightly acidic state.
- Toner/Astringent: Primarily suitable for adjusting the skin's pH back to slightly acidic after it has become alkaline from cleansing.
- Lotion/Cream: After pH adjustment, these act as moisturizers to keep the skin hydrated.
Therefore, the correct steps for using basic cosmetics are to adjust the pH with a toner/astringent after cleansing, and then provide sufficient moisture with a lotion or cream.
How to Choose a Moisturizer for Your Skin Type
It's good for our skin to maintain an appropriate level of moisture. It's important to choose a moisturizer that suits your skin type.
- Sensitive Skin: Applying too much moisturizer can actually block pores and lead to breakouts like acne.
- Oily Skin: If you cleanse too much and excessively remove oil from your skin, it can become dry, and this dryness can lead to other allergic reactions or dry acne.
- Dry Skin: It's good to apply a thicker cream-like product to balance the skin.
- Oily Skin: It's good to apply a lighter lotion-like product to keep the skin hydrated.
In conclusion, after thorough cleansing, it's important to keep the skin hydrated, and skin balance is paramount.
