I've voted for the ones I use most often and really like:
Elemis Pro Collagen Marine Cream
Decleor Hydra Floral
L'Occitane Immortelle Divine Cream
Other:
Murad Hydro Dynamic Ultimate Moisture
Decleor Iris Balm [night]
Decleor Neroli Balm [night]
Decleor Prolagene Gel
AD Skin Synergy [night]
High Street:
Clarins Super Restorative Day Moisturiser
Clarins Blue Orchid Face Treatment oil [night]
If I had to pick just one - Decleor Hydra Floral, as the hydration it offers is superb, as long as you are able to get on with the essential oils it contains.
