In Paris, what to purchase?

[Isabelle70]

I am in Paris and awake waiting for the family to wake up. What would be good to purchase from the pharmacy? Under 100ml as only hand baggage.
I can't use tretinoin as I have rosacea.

Caudalie premier cru 💕

Embryolisse Lait-Creme Concentre Cream

This works great as a primer and I love the clean fresh light scent. I always keep a tube in the bathroom cabinet.

Le Roche Posay products might be cheaper than the UK too, and most pharmacies in France stock a wide range.
