Actresses Han So-hee, Go Youn-jung and Suzy are known for their flawless, porcelain-like skin — a beauty ideal admired by many.

With Korea already in the grip of a scorching summer, many are taking extra precautions against sun damage, armed with hats, parasols and sunglasses. But for those who envy the actors' luminous skin, is it possible to achieve a brighter tone through consistent care?

Link between melanin and skin tone

Melanin is a natural pigment found in the skin, hair and eyes. It determines skin color and is stimulated by ultraviolet (UV) exposure. People with less melanin tend to have lighter, whiter skin.

When exposed to UV rays, the skin produces more melanin as a defense mechanism. This pigment rises to the surface, darkening the skin and resulting in what we commonly call a tan.

Skin regenerates approximately every 28 days, and as it does, melanin is naturally shed along with the outer layer of dead skin cells. This means that diligent skin care can gradually reduce accumulated pigmentation over time.

Can you make your skin brighter?

To maintain a fair complexion, it's essential to minimize melanin production or accelerate its breakdown. Since melanin is highly sensitive to external stimuli — like UV rays, inflammation, irritation and stress — avoiding these triggers can help restore and maintain a brighter tone.

Here are five effective ways to support radiant, healthy-looking skin:

First, UV protection is non-negotiable.

Applying sunscreen only during peak summer heat isn’t enough. Many celebrities apply SPF daily — even indoors or on cloudy days. Experts recommend using products with SPF 30–50 and PA++ or higher, reapplying every two to three hours. Accessories like hats, sunglasses and parasols offer added protection.

Second, exfoliate and use brightening skin care ingredients.

Skin clarity and tone depend heavily on exfoliation and the reduction of pigmentation. Use gentle exfoliants like AHA (glycolic acid) or PHA once or twice a week. Incorporate brightening ingredients such as niacinamide, arbutin or vitamin C. After daytime sun protection, apply a brightening serum in the evening. Laser toning is also an effective dermatological option.

Third, keep your skin well-hydrated.

Dehydrated skin can appear dull and uneven. Use a skin care routine that includes toner, essence and moisturizing cream — ideally with ingredients like hyaluronic acid for hydration and panthenol for soothing. Hydrating sheet masks two to three times a week, especially when chilled, can reduce puffiness and enhance radiance. A cooling cucumber massage is also great for post-sun skin.

Fourth, eat your way to brighter skin.

Diet plays a major role in skin appearance. Antioxidant-rich foods like tomatoes, blueberries, green tea and nuts help fight skin aging. Consume fruits and vegetables high in vitamin C — such as kiwi, strawberries and broccoli — and drink 1.5 to 2 liters of water daily. Taking vitamin C supplements on an empty stomach in the morning can increase absorption.

Fifth, sleep and stress control matter.

Skin regenerates during sleep. Aim for at least seven hours of restful sleep each night. Stress increases melanin production and can lead to duller skin. To promote better sleep, try drinking a warm cup of chamomile tea or doing light stretches before bed.
