But I’m talking about ingredients now, not designing products. Vitamin C and niacinamide have been shown to work effectively for numerous topical applications (less free radical damage, more collagen). Also skin lightening is one of their desired effects. But I would like to know if this effect might actually be dangerous long-term because surely less melanin = more uv damage. Or is the amount negligible (it’s not to the naked eye though)?

“But under real life conditions, since skin moisturization depends so heavily on atmospheric & biologic conditions, it would be tough to say exactly how long you’d have measurable moisturization.”
Would an humidifier in your bedroom be beneficial to skin? If so at what setting? How will this compare to moisturizing creams? -
@zaidjeber I actually do understand how vitamin c is supposed to work. But what I don’t know is: how much will the lower melanin concentration increase photosensitivity of the skin? And will this counter the positive effects of vitamin c?
Besides, the positive effects are only there for as long as vitamin c is applied, the lower melanin concentration is more lasting. -
Does this mean when one applies petrolatum at night and washes it off in the morning: the skin will be back to baseline at 12:00 (I’m not sure about TEWL benefits longevity)?
