This product should be back mid to late January. As an alternative, in the meanwhile you could look at the Exuviance Daily Corrector SPF35 - which is basically the same product (Exuviance and Neostrata come from the same stable) though Exuviance is SPF35, not 40!
 
NeoStrata Sheer Hydration is a lightweight, non-greasy daily moisturiser that provides both UVA and UVB sun protection for oily and blemish prone skin. Gently exfoliating the skin to promote cell renewal it also tones, corrects uneven skin tone and improves skin firmness.
 
Sheer Hydration also works well as a holiday moisturiser for those travelling to hot or humid climates.
 
This moisturiser minimises oil production, whilst still keeping skin hydrated and protected with an SPF40 sun protection factor.
