I used Serious Skin Care for about three years, basically the A line but I also tried the Olive Oil, Glycolic, Combination skin products (lime green colored container, such as copper serum and cream, etc.)- basically everything but Vitamin C and the anti-sag line they used to have in the lavender-colored container (don't know if they have it any more or not). At first it was okay but then like another person who posted said it just started to not do much for my skin. In addition, sometimes I would receive products and they would be old and dried out, or oils would have separated, or what happened lots of times was the products only came about 2/3 full. Back when I first ordered it around 1998 they containers were FULL just as advertised on TV. I was very put-off by the fact I was paying more for the products as time went on and progressively receiving less and less for my money, even though during on-air presentations they would show jars full to the brim with product and that simply was just not the case- basically false advertising. My skin is relatively sensitive and the glycolic definitely dried my skin a lot, the Olive oil clogged my pores terribly (might as well just have spread Crisco on my face instead of paying $70 for the Olive Oil kit I got), and the Liquid Laser product literally caused chemical burns to my face but did nothing to remove stray hairs on my face and legs, even with leaving it on the maximum amount of time. I totally gave up Serious Skin Care about a year ago and have come across a few good skin care lines since, including:
1. Good Skin (manufactured by Estee Lauder for Kohl's Department Store under the "Good Skin" label) These products are fantastic and have been my standard since forgoing Serious Skin Care. I use the lime green colored line for combination skin and it is really wonderful- gentle enough for the sensitive areas of my face while reducing and balancing out oily spots. The daily moisture cream is GREAT. They have lots of different, comprehensive lines for all different kinds of skin types.
2. be.fine- Skin care line carried only at CVS drugstore (available through their website online and at their retail stores). They have sample kits of night products and a sample kit of day products, each selling for $20 (3 pieces to each sample kit), in addition to about 10 different full size products in their line. I have been using these products for a week now and the texture of my skin is so nice and soft! I am a big fan of the cocoa night cream since it is nice and light (has no scent, not even a slight hint of chocolate smell). The line is based on food products which provide antioxidants and vitamins essential for good skin health. be.fine has their own website where you can find out more.
3. Garnier Nutriesse- This will be the next skincare line I try since my budget may be getting kind of tight coming up with our mortgage payment for our new house we just moved into. These products received very good reviews on Drugstore.com's website and are reasonably priced. I will update this post once I have tried the products but they look very good and can be found easily at any mass retailer.
If you are wondering why I listed several companies, even though Good Skin is my HG, I am always looking for the next best thing and will be writing reviews for a major Internet site on various skincare lines and products so I'm currently in the process of sampling and trying out new things.
I hope that this helps somewhat. As someone else said, if you want to try Serious Skin Care, go for a smaller kit that you don't have to invest much into. Personally, I would not waste my time and money even trying them as I feel there are much better products out there...just my opinion though.
