I don’t usually use a makeup primer (hey, I’m 23, I usually figure, why bother?). At the same time, however, I was lured when I recently discovered Bioelements Recovery Serum for Dry to Normal Skin ($62.00, Amazon.com), and addicted after. The product made my sensitive/normal skin appear very smooth and dewy, even under make-up.
The secret to Bioelements Recovery Serum is similar to yesterday’s Boots No. 7 Restore and Renew Serum: that is, heavy on the silicones. Bioelements Recovery Serum features cyclopentasiloxane and dimethicone in very high concentration. And similar to Boots No. 7 Restore and Renew Serum, the effects of the serum are primarily for hydration and cosmetic purposes. While Bioelements Recovery Serum does contain ceramide 3, soothing chamomile, and calming lavender extract, the Journal of European Dermatology and Venearology has questioned whether ceramide 3 has long-term barrier repair effects, and chamomile and lavender are both found in very low concentration.
When applying Bioelements Recovery Serum, the smell is identical to Vicks VapoRub, at least to me. The consistency of Bioelements Recovery Serum is thick due to the silicones, and takes about 1-2 minutes to drink in fully (I personally brush my teeth as it sinks in). Finally, it is hard to use a sunscreen under or over this primer, so I recommend Bioelements Recovery Serum as a make-up primer at night – not during the day.
Overall, however, Bioelements Recovery Serum is truly an excellent product and I will use it every night I leave the house! 
Overall rating: 8/10
As Napoleon Perdis would say, “Not to prime is a crime!” I totally agree!, It makes a world of a difference to make up finish.
Hey just a comment about lavender…2 studies have shown that it is cytotoxic to skin cells (one human fibroblasts, and the other one allium which is commonly used as a human skin model)
The title of the studies are
