This serum is a favorite of my two daughters after receiving facial scrub & serum kits for their birthdays. My youngest teen has very sensitive & reactive skin & she hasn’t had any problems with this serum, which (in combination with the honey scrub) leaves her skin super soft. She has been using it for 2 months. My eldest has some blemishes & an intense compulsion to pick at her skin, which is damaged from the habit (poor kiddo). This serum (with the honey scrub) is her new routine. After the first use, her skin felt softer & in the span of just two days she noticed a significant difference. She has now used the serum daily, for just over a week, & her skin is incredibly soft, her blemishes are reduced & she is so thrilled with the results that she is finding it is helping her resist some of the picking. She loves it! Neither are having any break-out issues from the oils & both have already asked me when I will be traveling to Boulder again, to get more. Luckily, for all of us, I can order online & intend to do so because I want in on the Precious Face Serum action, too! It’s worked for them in different climates, as well: rainy season in N. CA & spring in super-dry, S. AZ. This stuff soaks in well, smells divine & leaves my girls skin soft as a baby’s. I’m looking forward to trying it out on my 40 year old face & my 68 year old mother who has CRAZY-reactive skin & rosacea is tempted to give it a try! Thanks, Rebecca’s, for another excellent product.
