Are luxury skincare products just a waste of money?

Scrolling through her phone late at night, Ms. Li was suddenly startled by her dull and wrinkled face in the mirror. "I've used the most expensive face cream, so why is my skin getting worse?" Do you have the same confusion? Today, we'll unveil the scientific truth behind skincare marketing and guide you out of skincare misunderstandings.

Misunderstanding One: Do more expensive skincare products always have better results?

Mr. Zhang spends one-third of his monthly salary on luxury brand skincare products, but he has frequent allergic reactions instead. In fact, price ≠ effectiveness. The efficacy of skincare products mainly depends on:

• The concentration of active ingredients (for example, 2% niacinamide is safer and more effective than 10%)
• The stability of the formula (vitamin C is easily decomposed by light and requires special packaging)
• The absorption rate of the skin (molecules with a molecular weight greater than 500 daltons have difficulty penetrating the stratum corneum)

Laboratory data from Zhongshitong shows that the difference in moisturizing performance between an 80-yuan basic moisturizing cream and an 800-yuan product is less than 15%.

Misunderstanding Two: Does layering skincare products double the effect?

There are products for a 7-step skincare routine on Ms. Wang's dressing table, but it has led to "over-skincare syndrome". Scientifically proven:

• Using acids (AHA/BHA) together with vitamin C will neutralize and lose their effectiveness
• Niacinamide reacts irritatingly with strongly acidic products
• The skin has an absorption limit (usually 0.3 ml per application is already saturated)

The three-step simplified skincare method: Cleansing (the optimal water temperature is 32°C) - Repairing (with ceramides) - Sun protection (SPF30+PA+++ is a must every day).

Misunderstanding Three: Are natural ingredients always safe?

The label of "pure plant extract" makes many people let their guard down, but:

• The photosensitivity of lemon juice can cause dark spots (containing furanocoumarins)
• Undiluted tea tree essential oil can cause contact dermatitis
• Homemade face masks may have a hundred times more bacteria than the standard (laboratory environment ≠ home environment)

A 2023 test by Zhongshitong shows that 35% of products "purely natural" contain artificial preservatives. When choosing, look for the filing number of the National Medical Products Administration (query website: www.nmpa.gov.cn).

The ultimate answer to scientific skincare

The golden rules recommended by dermatologists:

• In the morning: Clean your face with clean water + Vitamin E cream + physical sun protection (hat/mask)
• At night: Clean your face with amino acid cleanser + retinol (use after building tolerance)
• Once a week: A clay mask (for oily skin) / A moisturizing mask (for dry skin)
