FAQ

Is DUO-A suitable for sensitive skin?
It’s best for users with established retinoid experience. New to Vitamin A? Try Serum 24 first.

Will it make my skin sun-sensitive?
DUO-A is buffered to minimise irritation but all retinoids increase sun sensitivity. Use a sunscreen that blocks both UVA and UVB with a minimum of SPF30 daily, even during winter.  When outdoors and in direct sunlight, re-apply a minimum of SPF30 every two hours. 

How soon can I expect results?
You may notice improved texture and tone within 2–4 weeks, with firmer, smoother skin in 8–12 weeks.

Can I use this alongside in-clinic treatments?
Yes! DUO-A is ideal for prepping your skin for Today & Tomorrow peels or microneedling
