This is one of those questions where more people get the answer wrong in the "trying too hard" direction than the "not enough" direction. The instinct is: if 3 sessions a week help, surely 7 help more. It doesn't really work that way with LED therapy, and it's worth understanding why before you settle into a routine.

The actual recommended frequency
For the VivaGlam Photon LED Face Therapy Mask, and pretty much any quality LED device in this category, the sweet spot is 3 to 5 sessions a week, 15 minutes each. That's it. Not daily, not once a week.
Here's the reasoning: LED therapy works through photobiomodulation - light energy gets absorbed by your cells and used to ramp up cellular activity, particularly around collagen production and, if you're using blue light, bacterial reduction. That process takes time to unfold at a cellular level. Bombarding your skin with light every single day doesn't accelerate the biology; the cells can only respond so fast regardless of how much light you throw at them.
Two phases: building and maintenance
The building phase (roughly the first 8 weeks). This is when you're establishing the habit and giving your skin the input it needs to start producing visible change. Aim for the higher end - 4 to 5 sessions a week - during this window.
The maintenance phase (after visible results). Once you're seeing the improvement you were after, you can usually drop to 2 to 3 sessions a week and hold onto the results. Collagen production and bacterial reduction, once established, don't disappear the moment you ease off - but stopping entirely will gradually reverse the benefit.
What happens if you skip a week?
Nothing dramatic. A missed week here and there won't undo weeks of progress - skin isn't that fragile. What actually derails results is chronic inconsistency: using it twice one week, not at all the next, once the week after. That pattern never gives your skin the sustained input it needs to build meaningful change.
Can you overuse it?
Technically, yes, though it's uncommon. Sessions significantly longer than 15 minutes, or multiple sessions in one day, don't speed anything up and can occasionally cause mild sensitivity, particularly on reactive skin. There's no upside to pushing past the recommended dose - think of it the way you'd think about sun exposure or exercise: there's a beneficial range, and going well past it doesn't multiply the benefit.
