Sunscreen: The most economical and effective anti-aging investment

90% of skin aging is caused by UV damage (photoaging), rather than natural aging.

UVA (accounting for 95%): The culprit of aging. It has strong penetrating power and damages collagen, leading to wrinkles and sagging.

UVB (accounting for 5%): The main culprit behind sunburn. It causes skin to become red, swollen, and hot.

I. Two key sun protection indicators: SPF and PA

SPF (Protection against UVB): Higher isn't always better. SPF 30 already blocks 95% of UV rays, and SPF 50 reaches 98%. Too high a value can result in oily textures and clogged pores. Therefore, there's no need to deliberately pursue an excessively high SPF number.

PA (Anti-UVA): Key to anti-aging. It is recommended to choose PA++++ to provide sufficient deep defense.


II. Physical vs. Chemical: Which one is right for you?

Comparison angle

Physical sunscreen

Chemical sunscreen

principle

It reflects ultraviolet rays like a "mirror".

Like a sponge, it absorbs ultraviolet rays and converts them into heat energy.

texture

It is relatively thick, whitish, and slightly sticky.

Lightweight, transparent, and easy to spread.

Security

High concentration . Does not seep into the bloodstream, suitable for pregnant women and children.

The ingredients are easily absorbed, raising health concerns.

Durability

It is effective immediately upon application, but it is easily rubbed off due to sweating.

It takes 20 minutes for the film to form, and it becomes resistant to abrasion after absorption.


III. Note: Chemical sunscreens and their potential endocrine risks

New research indicates that some chemical sunscreen ingredients are "bioactive," capable of penetrating the skin and entering the bloodstream, producing hormone-like effects, interfering with the endocrine system (EDCs), and potentially increasing the risk of diseases such as ovarian cancer.

5 Chemical Components to Watch Out For:

  1. Oxybenzone : Interferes with estrogen and testosterone, affecting fertility.
  2. Octinoxate : Common but can affect the thyroid and reproductive system.
  3. Octocrylene : It easily accumulates in the body, and the benzophenone produced after its degradation is a known carcinogen.
  4. Homosalate : High concentrations can interfere with hormone balance.
  5. 4-Methylbenzyl camphor (4-MBC) : Strongly interferes with the thyroid gland and is not approved for use in many countries.


IV. Common Misconceptions about Sunscreen

Sunscreen is essential indoors too: Glass windows don't block UVA rays, and your skin continues to age even when working or driving near windows. Reapplication is key! It's recommended to reapply every 2-3 hours.
