What to prioritise as the weather turns
Red (630nm) and near-infrared (830nm) are the wavelengths to lead with through autumn. They work at deeper levels in the skin and support the renewal processes that show as firmness and smoothness over weeks rather than days, exactly the kind of slow, structural work a season of consistency allows for.
Alongside that, bring in the Calming mode (blue 415nm with green 520nm) two or three times a week. Autumn brings sharp temperature swings between cold air outside and dry heat indoors, and it helps skin that flushes or looks reactive appear calmer and more even.
The PRO by Déesse PRO gives you the full spectrum in a single device, so building an autumn rotation is a matter of choosing the mode, not adding another tool to the shelf.
