Questions, answered
Can I use it morning and night?
Yes — it is designed for twice-daily use. In the morning, follow with sunscreen as the final step.
Will it play well with my other actives?
It layers comfortably in most routines. If you use strong exfoliating acids, alternate evenings to keep skin comfortable.
When will I notice a difference?
The glow and hydrated feel show up quickly; firmness and the look of lines soften gradually — that’s the slow-aging pace, and it’s by design.
