I do observe there is a Freshel White C Essence, but i don't believe it is the same as the night essence. The other product is in tube form, this is in a 40ml glass jar.
I have used it for close to 4 weeks now - I really have dropped half a shade in foundation (at least in Bobbi Brown)! I never thought whitening stuff really worked, well at least not on my hopelessly dark skin (NC40, Bobbi Brown 4.5 Warm Natural)... but Freshel has really changed my mind. I haven't used anything else in the range, only this, a pea sized blob on my cleansed and moisturised face just before I go to bed, and it really is working. Doesn't break me out, is non-greasy, smells inoffensive (no strong smells here), gel like consistency, not too expensive (US$18 or HK$135 on Adambeauty), very pleased with it and will repurchase along with other products in the Freshel range. Will update if I whiten further.
