Here is a copy of an email I sent today. It should help anyone using this amazing product..
Thanks for your call today. You told me that when you buy the Overnight Retinol Repair that the included Buffer runs out well before the Retinol Repair. I told you that these products couldn’t be purchased separately and can confirm that Dermalogica have no plans to split them in the future. The Buffer is actually a ‘free’ gift included in the Retinol box.
There are two simple solutions, however, and they're down to how you use the product.
The objective of the Buffer is that it eventually becomes redundant in your skincare regime. The Buffer is there to allow your skin to become accustomed to the Retinol Repair. After 6+ weeks if your skin has adapted you won’t need to use the Buffer anymore.
Typically the process is as follows for daily use:
First 3/4 weeks = 2 parts Retinol and 2 parts Buffer
Weeks 5/6 = 3 parts Retinol and 1 part Buffer
Weeks 6+ = 100% Retinol
Different skins will react differently to this process. You need to monitor your skin over this process and should you encounter skin tightening, mild dermatitis, skin drying / flaking then the Buffer needs to be increased. If that doesn’t recover the skin, you must stop the whole process, wait for the skin to get back to normal and then start again.
The Buffer is a moisturiser that, although tailor made to work with the Retinol Repair, can also be used as a general moisturiser. Customers often keep the Buffer as a travel pack moisturiser.
If you run out of Buffer but still have Retinol Repair left, you can also use Skin Smoothing Cream or Intensive Moisture Balance as alternatives.
I hope that helps, please feel free to contact if you need any more help
