When cloudy days set in, it’s easy to take UV lightly. Even on cloudy days, some UV passes through the clouds.<\/p>\n In particular, the UV most linked to pigment (UVA, the long wavelength that reaches deep into the skin) passes through glass and clouds to a considerable degree.<\/p>\n Add summer heat and humidity, and the skin develops fine inflammation more easily, and that irritation makes melanin (the pigment created to protect the skin) more active.<\/p>\n So “a rainy day = safe from UV” simply isn’t true. Not all pigmentation is the same. When the cause and depth differ, the approach changes too.<\/p>\n They may look similar on the surface, but because their depth differs, they can’t all be managed the same way.<\/p>\n So rather than self-diagnosing “this is melasma,” it matters to first distinguish which kind of pigment it is.<\/p>\n This doesn’t mean home care is meaningless. In fact, the basics are built at home.<\/p>\n Still, there are clear limits.<\/p>\n Light pigment near the surface (epidermis) may settle in tone with consistent home care. That’s exactly why so many people say, “I’ve used brightening products for months and nothing changes.”<\/p>\n The core of clinical pigment care is not “strong, all at once” but “matched to depth, in stages.”<\/p>\n Laser toning and pico toning (breaking pigment into fine particles with short pulses) work on the idea of gradually breaking pigment down so the body naturally clears it.<\/p>\n Here is something I want to share honestly.<\/p>\n That’s why I believe the most important thing in pigment care is not the name of the device, but the process of first reading “what type of pigment you have and at what depth.”<\/p>\n Yes. Even on cloudy days, a significant portion of the UV linked to pigment still passes through. Indoor windows are no exception, so I recommend applying it daily. That said, products and lifestyle differ for everyone, so it’s best to review them together during a consultation.<\/p>\n It varies with the type, depth, and skin condition, so it’s hard to state definitively. It’s often done over several sessions, and the number and interval are best decided after a specialist’s diagnosis.<\/p>\n Not necessarily. Excessive irritation can actually leave pigment behind, so a conservative approach matched to depth is safer.<\/p>\n They’re often hard to tell apart by appearance alone. Since the direction of care changes depending on the type of pigment, I recommend getting a diagnosis first.<\/p>\n Pigment care changes completely depending on “why it formed and at what depth it sits.” If you’re curious which applies to you, a specialist consultation is more accurate than self-diagnosis.
