For the one winter product that will give you the most bang for your buck, I love Decleor's Neroli Aromessence Oil - it's certainly not cheap, but it's incredibly high quality, and so concentrated that the tiny little bottle will last close to a year.Decleor's Aromessence line has several specialized blends for each skin type, but the Neroli is the most versatile - a drop or two before your moisturizer both balances and hydrates the skin, and actually helps to pull the ingredients of you face cream deeper into the dermis. It gives a healthy glow, smells incredible and luxurious, and is made of the highest quality ingredients - it takes 100 kilos of orange blossoms to distill 100 g of the Neroli extract.
Its packaging is a pretty, modern glass bottle, but it's been recently redesigned - a shame I think, because it used to look lovely sitting on the dressing table - a vintage, stoppered affair that looked very decadent and luxurious. Oh well. Apparently not everyone's tastes run as baroque as mine. Regardless, it's still a beautiful product that I recommend to everybody.
