In Hong Kong, the summer UV index often reaches high or even very high levels. Even a brief outdoor excursion can cause enough damage to the skin. Post-sun redness, peeling, and dullness each have different causes, and their treatment methods vary greatly—mistaking the steps can actually worsen hyperpigmentation.

FAQ|Common questions about post-sun repair
What is most effective for sunburn? ▸
The priority after sunburn is to reduce inflammation and soothe, not to immediately use whitening products. It is recommended to choose a lightweight serum that contains soothing and moisturizing ingredients, is alcohol-free and fragrance-free, such as
SOS Booster Deep Hydrating Serum, to quickly hydrate and calm the skin, and then seal in moisture with a face cream.
How long does it take for tanned skin to return to its original color? ▸
The natural melanin metabolism cycle typically takes about 4–8 weeks. Focusing on barrier repair, consistent daily sun protection, and adequate hydration can help accelerate the skin tone's return to normal. Avoid excessive use of irritating whitening ingredients, as they can make the skin more fragile.
Can I peel off sunburned skin? ▸
It is not recommended. Forcibly peeling off skin can damage the underlying new skin that has not yet recovered, increasing the risk of hyperpigmentation and sensitivity. At this time, you should focus on moisturizing, let the peeling skin shed naturally, and temporarily stop using exfoliating products.
Can I use a face mask on sunburn? Which one do you recommend? ▸
Yes, but you need to choose one that is alcohol-free, fragrance-free, and primarily focused on soothing and hydration. We recommend
SOS Booster Anti-Pollution Hydrating Mask; its Hibischa™ formula effectively soothes redness and improves dullness, suitable for both emergency post-sun repair and daily maintenance.
What should I do if my skin is red after sun exposure? Do I need to see a doctor? ▸
Mild post-sun redness is a normal acute reaction, which usually improves within 24–48 hours after cooling down and hydrating. If the redness is severe, accompanied by blisters, fever, or persists, it is advisable to seek medical attention as soon as possible.
