Actress Jun In-hwa, 60, is drawing widespread admiration for her remarkably clear, firm, and youthful complexion.
Jun recently posted a photo on social media showcasing her radiant look while softly smiling and holding her pet dog. Even with little to no makeup, her skin appeared smooth and virtually blemish-free, prompting a wave of praise from fans who praised her elegance and asked for her skin care secrets.
Long celebrated as an epitome of timeless beauty, Jun credits her youthful appearance primarily to deep skin hydration and regular physical activity. She previously revealed that she constantly carries a facial mist in her bag to combat dryness, noting that dehydrated skin suffers just as much as a dehydrated body.
Jun married actor Yoo Dong-geun in 1989, and the couple has a son and a daughter. Here is a closer look at the scientific principles behind her skin care routine.
Moisturizing Is the Foundation of Youthful Skin
Adequate hydration is fundamental to skin health, but dermatologists stress that preventing moisture loss is far more crucial than simply applying water to the surface.
The stratum corneum, the outermost layer of the skin, must maintain a moisture level of 20% to 30% to remain smooth and elastic. When moisture levels drop below this threshold, the skin barrier weakens, leading to dryness, heightened sensitivity to environmental stressors, and more pronounced fine lines.
While toners and facial mists offer immediate, temporary hydration, moisturizers such as lotions, creams, and balms create a protective barrier that seals in moisture. The American Academy of Dermatology (AAD) advises applying moisturizer generously immediately after cleansing to preserve barrier function. Mists formulated with barrier-supporting ingredients like hyaluronic acid, glycerin, and ceramides are particularly beneficial.
How to Use Facial Mists Correctly
Facial mists effectively relieve tightness in dry environments, making them ideal for air-conditioned offices, heavily heated rooms, or long flights.
However, repeatedly spraying mist without sealing it can actually worsen skin dryness. As the sprayed surface water evaporates, it can draw moisture out from deeper layers of the skin. To maximize benefits, gently pat the mist into the skin after spraying and follow with a lightweight cream or lotion to lock in hydration. Consumers should also avoid mists containing high concentrations of alcohol or synthetic fragrances, which can irritate sensitive skin.
During humid summer months, frequent outdoor misting is generally unnecessary and can cause makeup to breakdown or leave skin feeling sticky. However, misting remains useful in air-conditioned indoor settings when paired with a cream. Overall, consistent sun protection, adequate fluid intake, and a lightweight moisturizer tailored to one's skin type are more impactful during summer than misting alone.
Aerobic Exercise Enhances Circulation and Skin Repair
The daily walking routine Jun practices also delivers direct benefits for skin health. Regular aerobic exercise improves systemic blood circulation, increasing the delivery of oxygen and vital nutrients to skin tissue while facilitating the removal of cellular waste.
Furthermore, studies show that regular exercise reduces levels of cortisol, a primary stress hormone, while promoting restorative sleep—both of which accelerate skin repair and regeneration.
To support optimal skin health, medical experts recommend aim for approximately 150 minutes of moderate-intensity aerobic exercise per week, staying well-hydrated before and after workouts, and thoroughly cleansing the skin after sweating. For outdoor exercise, applying a broad-spectrum sunscreen is essential, as ultraviolet radiation remains a primary driver of premature skin aging.
