Melasma caused by UV rays: How to treat and prevent recurrence
Everyone knows the leading cause of melasma, age spots, brown spots, freckles, etc.: Direct sunlight but the skin is not protected or covered.

However, do you know how sunlight (also known as ultraviolet rays, UV rays) causes melasma, how to prevent and treat melasma caused by UV rays? Let's find out now.

- How does sunlight affect the skin?

First, let's find out how sunlight affects the skin.

In ultraviolet rays, there are 3 types of UV:

• UVA is the ray with the longest wavelength, has the strongest impact and accounts for the largest percentage. UVA rays account for 95-97% of sunlight. In particular, UVA rays shine all year round, maintaining a steady intensity. And you know what else? UVA rays can penetrate thin materials! Materials such as clothes, thin curtains, glass doors are UVA that can penetrate and affect the skin! And the harmful effects are that UVA causes wrinkles, melasma, dark spots, age spots and skin aging, especially in women.

• The second is UVB rays, accounting for a small proportion of only about 3-5% but is dangerous because it contains more energy and has greater harmful effects. UVB rays strongly affect the surface of the skin and cause redness, sunburn and worse, skin cancer. Luckily for us, this ray does not penetrate objects, but has the ability to reflect light such as seas, lakes, rivers, water. That is also the reason why you will often get dark, red skin, sunburn when traveling to the beach, even if you are only in the shade if not covered.

• UVC has a short wavelength so it is completely blocked by the ozone layer, so don't worry about this UV ray!

In other words, it is the same UVA and UVB rays that affect the skin and cause skin phenomena such as uneven skin tone, dark spots, melasma, freckles, wrinkles, and skin aging.

Melanin - the warrior that protects the skin

Melanin protects the skin from sunlight. When stimulated by sunlight, it will rise to protect the skin.

When the skin is exposed to sunlight, the skin's keratin glands will stimulate increased melanin production to protect the skin from the effects of UV rays as well as substances that oxidize the skin. Melanin will absorb and convert sunlight into heat to help filter free radicals and prevent tumors, protect and heal wounds, and skin inflammation.

But sadly, our bodies do not know how much is enough to produce. Therefore, after each time melanin is activated to fight the harmful effects of UV rays, an excess amount of melanin appears. They accumulate in the epidermis, dermis, and hypodermis and manifest as brown spots, age spots, melasma, and freckles on the skin, affecting the aesthetics of the skin.

How to prevent melasma caused by sunlight

From the knowledge about melanin in the skin above, we can draw out an effective method of treating melasma. That is, it is necessary to minimize the skin's exposure to sunlight, avoiding the melanin synthesis process from happening more and more quickly.

"Prevention is better than cure" before learning how to treat melasma caused by UV rays, let's see how to prevent melasma caused by sunlight to keep your skin healthy and radiant.

- Avoid direct sunlight

Try to avoid exposure to sunlight in the middle of the day, when UVB and UVA rays are strongest. If you need to be exposed to sunlight, find a shady place or bring an umbrella to shield yourself.

- Use sunscreen

Using sunscreen ( Recommended LADEEN SUNSCREEN ) is one of the important measures to protect the skin from the effects of UV rays. Choose a sunscreen with a high SPF and apply it evenly to the skin before exposure to sunlight.

- Wear a hat and cover up when going out

Wear a wide-brimmed hat and wear a sun mask to protect the face and neck from the sun. This is a simple but effective measure to protect the skin from the effects of UV rays.

- Use sun-protective clothing and other protective means

When going out during strong sunlight, wear long-sleeved shirts with UPF (Ultraviolet Protection Factor) to help protect the skin from UV rays.

In addition, you can also use sunglasses, umbrellas, or sunshades to protect the entire body from sunlight.

Treatments for melasma caused by sunlight

If you already have melasma, there are a number of treatments and therapies that can help lighten and fade the melasma. Here are some popular methods:

- Using serum to treat melasma ( Recommended LADEEN MELASMA Serum) and brighten skin

Serum to treat melasma is an effective treatment method to help fade brown spots and dark spots from mild to moderate. With a lighter texture than cream, serum easily penetrates deep into the skin, providing active ingredients such as glycolic acid, salicylic acid, niacinamide, ... to improve skin pigmentation and brighten the skin safely.

- Reasons to choose serum instead of cream:

Deeper absorption: Serum has a thin, light texture, easily penetrates deep into the skin layers, bringing faster and more obvious effects.
High concentration of nutrients: The active ingredient content in serum is often higher, helping to optimize the ability to fade melasma and restore the skin.
