I use both the Neroli and Melissa and Bulgarian Rose Otto Emu and Lypo C in place of other serums. They actually work to moisturize, firm, and soften wrinkles. I am 70 and believe in keeping my skin healthy and radiant. I had spent $160 on a big name serum, it made my face soft but not much more. The serum didn't last 3 months! I was in Cost Plus for something else when I saw the serums. At $19.99 per bottle I bought both. Great investment! Not only does it do wonders for my complexion, and they smell great, both serums take away the creapiness in my upper arms. That creepy skin makes it difficult to go sleeveless. I apply it in the morning and for hours both my face and arms are much smoother. I am a nature girl, no botox or surgery for me. I plan to keep using the serums, Rose Otto at night and Neroli Melissa in the day. No more expensive serums for me!
