This is a case where we'd rather give you the honest, slightly less exciting answer than the one that sells better - because overselling LED therapy's role here would set you up for disappointment, and that's not a fair trade for a bit of extra marketing shine.

The direct answer
LED light therapy does not directly lighten dark spots or hyperpigmentation the way targeted actives do. It's not built to inhibit melanin production, which is the actual mechanism behind fading dark spots. What it can do is support the broader skin health context that helps dark spots fade somewhat faster - a supporting role, not a primary treatment.
Why this distinction actually matters
Dark spots - whether from sun damage, post-acne marks, or age-related pigmentation - form because of excess melanin production in specific areas of skin. Fading them requires either inhibiting further melanin production (which ingredients like hydroquinone, azelaic acid, tranexamic acid, and vitamin C do) or increasing skin cell turnover to shed pigmented cells faster (which retinoids and exfoliating acids do). LED light doesn't work through either of these mechanisms directly.
What LED therapy actually contributes here
Red light and inflammation. For post-acne dark marks specifically, red light's anti-inflammatory effect during the active breakout phase may reduce how intense the resulting mark becomes, since prolonged inflammation tends to worsen post-inflammatory hyperpigmentation.
Supporting overall cell turnover. The cellular activity increase from LED therapy modestly supports faster skin renewal generally, which can contribute to marginally faster fading of existing marks over time, layered on top of whatever targeted actives you're using.
What it definitely does not replace: SPF. This is the single most important factor in pigmentation management, full stop. UV exposure actively worsens existing dark spots and creates new ones - no amount of LED therapy compensates for skipping daily sunscreen if pigmentation is a genuine concern.
A realistic approach to dark spots
If dark spots are your primary concern, the priority order should be: daily broad-spectrum SPF (non-negotiable, the foundation everything else depends on), a targeted brightening active (vitamin C, niacinamide, azelaic acid, or a dermatologist-prescribed option for more stubborn pigmentation), and LED therapy as a supporting layer rather than the main event. The VivaGlam Photon LED Face Therapy Mask fits into that third position well, particularly for the general skin brightening and post-acne mark support it offers, but it shouldn't be relied on as your primary pigmentation strategy.
When to see a dermatologist instead
For melasma, stubborn or widespread hyperpigmentation, or dark spots that aren't responding to consistent over-the-counter actives after several months, a dermatologist can offer more targeted options - prescription-strength ingredients, chemical peels, or laser treatments specifically designed for pigmentation, which go well beyond what any home routine, LED-based or otherwise, can achieve.
