Park Semi "The secret to my skin that received praise at the dermatologist?" ... How I use cosmetics

Comedian Park Semi revealed a simple yet effective skincare method.

Recently, a video titled "[Q&A] How much do I earn? What procedures did I get? How do I manage my mental health? I'll be honest with you" was uploaded on the YouTube channel 'Hello Semi'.

Park Semi said, "I didn't know I would have so many questions for Park Semi," and answered questions about skincare methods. He mentioned, "I've been doing this all along, but there's a method I was praised for by the dermatologist," referring to a 'cosmetic diet.'

Park Semi said, "I used to apply multiple layers of cosmetics, but now I think it's better to apply skin toner, cream, essence, and lotion every 3 to 4 hours." She also explained, "I keep lip balm and skin products in places like the bathroom, bedroom, and living room," adding, "If I want to go to the bathroom while sleeping, I go, then apply cream and lie down again."

Applying a lot of cosmetics doesn't necessarily improve your skin... It can even have adverse effects.

Semmi Park mentioned 'cosmetic diet' as a skin care secret, which refers to reducing the number of skincare products applied to the face. In the past, it was fashionable to layer up to ten products, such as toner, lotion, cream, essence, and ampoule. However, recently it has been revealed that this method can clog pores and burden the skin, leading to a trend of reducing the number of cosmetics used.

According to actual research findings, there is little correlation between using many types of cosmetics and skin health. The research team from Chung-Ang University's Graduate School of Medicine, Food, and Pharmaceutical Sciences, compared the skin of a group using only two types of cosmetics (skin toner and lotion) with a group using four types (skin toner, essence, lotion, and cream), and no significant difference was observed.

If ingredients collide, chemical reactions may cause pigmentation and inflammation.

Even with basic skincare products that are not tinted, applying an excessive variety of products can have counterproductive effects contrary to expectations. Ingredients that remain on the surface without being absorbed into the skin meet oxygen and transform into lipid peroxides, which can generate reactive oxygen species and accelerate skin aging.

Unexpected chemical reactions can occur between cosmetics, leading to pigmentation and inflammation. For example, applying products containing retinol, which is known to improve wrinkles, and vitamin C, which has whitening effects, at the same time can interfere with each other's absorption into the skin and cause stinging or burning sensations. This is because retinol is fat-soluble, while vitamin C is water-soluble.

Meanwhile, if the areas to be treated are dry and the T-zone is oily, applying different skincare products for each area can be an effective method. Use oil-free products on the forehead and nose, where sebum secretion is active, and apply products rich in oils and nutrients to dry areas such as the cheeks, chin, and around the eyes.
