Good to Know: Begin with use every second to third evening and slowly build use to every evening or every second evening. If your skin starts to feel itchy, tight or a little sensitive, stop for a couple of nights and then resume application. Use only at night and apply O Mineral Pro SPF 30+ every morning, no excuses!

Choosing your Retinol: If you’re new to Retinol, it’s been a while or you can’t remember what percentage of Retinol you’ve used previously start with a 0.5% strength; either Potent Retinol Serum or Retinoic Oil - the Oil is a better choice for dry and/or sensitive skin. If you’ve already been using a prescription or clinical strength Retinol go for the big-guns in Retinol Concentrate.

Important Information: As a precaution, O Cosmedics recommends avoiding products, including this one, containing Salicylic Acid and Retinol during pregnancy and breast feeding.
