Go for Nuxe- the honey lip balm and Huile Prodigieuse are sumptuous. That scent....Nuxe Rêve de Miel night cream, Micellar Cleansing Water with Rose Petals (so pretty!), Gommage Corps Fondant NUXE BODY- a lovely soft body cream with good 'slip',
I also stock up on Vichy as their facial wash off gels are brilliant at waking me up, they don't tighten my face and smell lovely too. Try Purifying Foaming Cream Cleanser.
Klorane is super inexpensive and more widely stocked-go for the cornflower eye make up remover, the peony shampoo and the children's ranges. Klorane Superfatty Shower Gel Aquatic Garden is designed to the dry and sensitive skins and I use this too. THE shampoo to use to help post pregnancy hair thinning is Klorane Quinine B6 Shampoo - This strengthening shampoo is perfect for people suffering from hair-loss and is specially formulated for dull, tired-looking hair.
Klorane Dry Shampoo with Nettle.The only one I would use because it has a natural scent.
Biafine ointment is particularly great on burns and dry chapped skin.
Bioderma Crealine H2O - a make-up remover that is sensitive enough to remove eye make-up as well, and considering it is for all skin types it does a great job of removing make-up properly and quickly. It feels like silky water on the skin and has a really cool medicine style bottle.
Avibon is French vitamin A cream, and it’s sold there over-the-counter, no prescription required. It’s not as strong as Retin-A, mind you. But great fro wrinkles, sun damage and general war wounds of ageing.
Homeoplasmine ointment is one of those rare Parisian chemist finds - a staple for make up artists, it goes on smooth and matte under make up - and overall miracle worker for chapped, dry, flaky skin everywhere!
Embryollise is a good range. Try Lait-Crème Concentré.
Cosmence moisturising eyes hydrasource- a push up cool gel stick that can be kept in the fridge to be ultra cooling.
Agnes b rose cleanser-Démaquillant 3 en 1 à la rose- I adore Agnes B and if you can find a jar or tube of Apricot correcting cream, snap it up. i have been using this since 1994 and it is amazing for a warm glow on tired grey winter skin. Agnes B- Correcteur de Vernis : Maquillage, Ongles, Soin des ongles, a nail varnish remover in a pen was THE first of its kind and the best in my eyes. Smart black and white packaging too.
Le Petit Marsellaise Douche & bain extra doux aux lait d'acacia- gorgeous acacia flower shower wash, bought from Monoprix for pennies. The other scents are good too- nut, vanilla.
Because Martinique is a French departement, the French have a lot of Caribbean and also Polynesian scents and products, The Monoi tiare tahiti, coconut oil gardenia scented oil is in most supermarkets and you'll also find Caribbean style oils and products scented with flowers. I slather this oil on year round and have used it to make shoes supple (dark coloured ones- rub it on inside. I saw this tip on a blog).
Elmex toothpaste. This toothpaste is highly recommended by dentists for its high concentration in fluoride and since it is always on offer in French parapharmacies, you have no excuse not to pop it in your basket. :)
Eau Jeune Eau Fraiche, especially the lemony one in the green glass bottle is sold in all supermarkets and is a lovely, lovely body splash, an EDT and something I have been using since I was eleven and first saw it on my French friends bathroom shelf.
Finally, this may not be your thing but the French have all major OTC medicines available as suppositories. I always used to stock up on rectal (PR) paracetamol, ibuprofen etc because they are far gentler on the stomach than the oral route. Also useful for babies and young children- if you can hack inserting them!
