☀️ Stronger UV from May, and the Rise of Melasma

☀️ Is the pleasant weather for outings a preview of melasma? A complete guide to preventing melasma

Hello, this is Yonsei Bomvit Dermatology.

Warm and sunny May means more time spent outdoors,

but from the skin’s perspective, it is the season when melasma begins.

That is because, along with stronger UV exposure, melanin activity begins to rise in earnest.

If you do not manage it carefully from now, melasma can settle in more deeply during the summer.

Today, we will explain why May UV is dangerous and summarize practical ways to prevent melasma in advance.

Melasma around the eyes caused by UV exposure

1️⃣ Why is May UV a preview of melasma?

✔ Both UVB and UVA increase at the same time

Starting in May, both UVB (which causes skin burns and blemishes)

and UVA (which penetrates the dermis and causes melasma and aging) become stronger.

The weather may feel comfortable, but your skin is already being irritated.

✔ The time when melanocytes awaken

Melasma does not appear all at once.

Starting in May, the skin gradually responds to UV exposure,

melanin production becomes more active, and it appears as darker pigmentation in summer.

✔ Once melasma settles in, it is difficult to remove

Pigmentation that forms deep within the skin often requires repeated laser treatments,

and because it is sensitive to irritation, prevention is important.

2️⃣ Melasma prevention: 5 things to start doing now ✔

✨ 1. Use sunscreen every day, generously, and thoroughly!

• Even indoor workers are exposed to UV through windows

• Choose products with SPF 30–50 and PA+++ or higher

• Apply once in the morning → reapply once in the afternoon when outdoors

• Pay special attention to the cheekbones, under the eyes, and bridge of the nose, where melasma often develops

✨ 2. Use a hat + sunglasses + parasol for secondary protection

• Very effective for blocking direct sunlight

• Essential especially during exercise and outdoor activities

• Wide-brimmed hats or products with UV-blocking features are recommended

• Since hats and sunglasses cannot replace sunscreen, they must be used together

✨ 3. Protect from within with antioxidant ingredients

• Vitamin C, niacinamide, glutathione, astaxanthin, and more

• May help suppress melanin production and prevent pigmentation

• Choosing products with low skin irritation and using them consistently can help prevent melasma

✨ 4. Remove sebum and dead skin cells with as little irritation as possible

• Rubbing the skin too hard increases the risk of pigmentation

• Take care of the skin as gently as possible

✨ 5. If you feel early signs of melasma, consult a dermatologist

• Faint discoloration, gray/brown shadows without clear borders

• When makeup does not go on well, or the under-eye area feels dull

• It is effective to prevent progression early with laser treatment or brightening care

📖 In closing

Melasma does not suddenly appear in summer,

but begins to quietly accumulate and settle in from May.

The sunnier the month of May, the more carefully you should protect your skin.

Before melasma deepens, there is no better treatment than prevention.
