Rocket America will be sharing the aging management methods and experiences of its challengers for four months under the theme, " Same age , different aging speed ? My own aging management method was OOO . "
We aim to complete an encyclopedia of ' Youth Reset A to Z' by collecting the anti-aging management methods and experiences of 30 challengers on different anti-aging related topics every month .
[ The first topic of the ' Youth Reset A to Z' encyclopedia: My own anti-aging secret management method]
Ep1-1. My Secret Anti-Aging Care Method _ Skin Care
The first topic of the 'Youth Reset A to Z' encyclopedia is " My own anti-aging secret management method . "
The main goal of anti-aging is to maintain a healthy lifestyle ,
It is said to minimize the external and internal symptoms of aging and improve the quality of life .
Rocket America conducted a survey on aging management methods and experiences among 30 challengers divided into 4 categories , and selected the top 2 most common answers in each category .
In this episode, we covered “ skin care ” among the four areas .
#1 Honey Glow Skin Care
Q: As we age, our skin loses elasticity and wrinkles appear.
Do you have your own wrinkle or skin care routine to prevent this?
Top 1. When going out , apply sunscreen thoroughly .
“ It has been reported that approximately 80% of facial skin aging is due to ultraviolet (UV) exposure.”
UVA is a major factor in photoaging because it has a longer wavelength and penetrates the skin more deeply than UVB, causing the irregular spot pigmentation associated with photoaging.
√ So why should you use sunscreen every day ?
There is evidence that using sunscreen daily plays an important role in preventing photoaging .
Experiment
In a study of 12 subjects, each subject was exposed to simulated solar radiation on two areas of their buttocks: one with sunscreen (SPF 30) that provided UVA protection, and the other with no sunscreen .
< Experimental Results >
Unprotected skin showed significant photoaging, including significant melaninization and increased thickness of the stratum corneum and granular layer . In contrast, the skin of subjects who applied sunscreen (SPF 30) showed significant improvements in skin texture , clarity , and blotchy and prominent pigmentation , with 100% of subjects showing improvements in skin clarity and texture .
√ Do I really need to check the SPF of my sunscreen ?
Visible light and infrared light play a significant role in photoaging , and SPF is an essential factor to consider when choosing a sunscreen . This is because broad-spectrum sunscreens with a sun protection factor (SPF) >30 block both UV and visible light, reducing their impact on photoaging .
To prevent photoaging caused by the sun's ultraviolet rays, you should use sunscreen with an appropriate SPF every day .
In recent years, the perception of sunscreen use has shifted from simply protecting against UV-induced erythema to providing broader protection against not only erythema but also photoaging , pigmentation disorders , DNA damage, and photocarcinogenesis .
In conclusion, while it is important to apply sunscreen every day , it is more important to apply sunscreen with an appropriate SPF every day .

Top 2. Apply moisturizing cream to keep your skin moisturized .
“ Skin moisture status = skin aging”
√ As we age, our skin loses moisture ?
As we age, our skin naturally begins to lose moisture , which reduces its elasticity and water-retention capacity . Dehydration weakens the skin barrier , making it more sensitive to external irritants and accelerating signs of aging, such as wrinkles , loss of elasticity , and sagging skin .
Simply put , skin hydration is directly linked to skin aging . Maintaining adequate moisture improves skin elasticity and appearance, and can even delay the formation of wrinkles . Dehydrated skin can lose elasticity , develop deep wrinkles , and appear rough and dull .
√ If I apply moisturizer , will it really fill my skin with moisture ?
Experiment
Group 1: Group that applied moisturizer
Group 2: Group that did not apply moisturizer
Experimental method : Apply moisturizing cream to the entire face and measure moisture content over time.
<Experimental Results> 
As shown in the graph above, the skin moisture content of Group 1 was higher (=lower dryness) and did not decrease over time. Conversely, the skin moisture content of Group 2, shown in the blue graph, decreased over time.
Studies have shown that ingredients like hyaluronic acid , glycerin , and ceramides in moisturizers attract moisture to the skin and prevent it from evaporating . These ingredients help keep skin soft and hydrated , and are effective in preventing skin aging .
Additionally, moisturizers help reduce signs of aging by increasing the skin's ability to retain moisture , improving its appearance and texture . Moisturizing is essential for strengthening the skin's barrier function and maintaining moisture levels .
Therefore , we can see that continuous moisturizing is necessary to delay skin aging , and moisturizers act as an important factor in preventing aging .
