Before use, use a product with hyaluronic acid like Quasar's "silk". The only other product that has as much of this is Cellex C 5B. After, use your normal routine, serums for wrinkles or retinol products plus a great moisturizer. See my review for my routine. However, ask the experts at Skinstore or where you get facials for their reccomendationtions too. Everyone's skin is different.

I don't know anything about md formulations or vita a plus products.
I answered the first question in my review, but I use the Skin Medica TNS Regeneration System: Toner first, Regeneration system, NIA24 for dark circles and eye wrinkles, Strivectin SD (takes 45 days to work, and I don't know if I really need it anymore, but I have been using it so long I am afraid to stop.) then during the day an SPF 15 product (MD Forte right now, may change to Roche Posay) on face hands arms decolletege.

Yes! I use it under my eyes and around my mouth mostly, because that's where I see the best results. You just have to be careful around the eyes to make sure that the light is not shining into your eye at all.

I'm not sure about the wavelength but you cannot use it on eyelids or directly on your eyes.

Both the Quasar Red and Blue are LED light therapies. The Blue is used for acne prone skin and the Red for normal skin/anti-aging rejuvenation. Though the Blue and the Red can be combined for acne prone skin. Visit the Quasar website. They are happy to answer any questions regarding their products.

LED light therapy It is not the same thing though as a Photo Facial procedure if that is what you mean when referring to Photo light therapy. For further information on various forms of light therapy I would suggest Milady's Aesthetician's Series "Lasers and Light Therapy" book. Easy to read in layman's language and it describes the various types of light therapies, what they do and how they do it and results that can be expected; along with various Laser procedures.Very much worth the time and money to invest in some of this series of books. Indeed they are a wealth of information when it comes to sorting through the confusion among various products, skin care tools and procedures. Check them all out on Amazon. You will not be sorry to have bought one or two. If anything you'll be better informed and likely more satisfied with the product you look to purchase and use.

I do. Every night for a year, no problem. Be sure to exfoliate with something like Clarisonic, Dermabrasion or Philosophy peel or you will find little bits coming off your face at times. This is your skin doing its own exfoliation.

Just looking at the product page it doesn't look like it has a 60 day money back guarantee, just the normal 30. The quasar does have a 5 year warranty through the manufacturer.

Call the Skinstore and ask.

Before you use the baby quasar you must thoroughly clean your skin and dry it. Then use a clear serum containing hyaluronic acid. The company that makes Baby Quasar has their own, sold through Skin Store, or you can use others. Hydra 5 B-Complex Cellex C Enhancer works also. I have not used any others. This must be on your face or other area of use, prior to using Baby. After, you may use any of the products you usually use. If you use it during the morning, follow your morning serum and moisturizer plus spf product regimen, at night, your night regimen of serum, moisturizers etc. I use several things both night and morning due to my age, but whatever is working for you is fine.

This is something you should ask the company and your dermatologist about. It goes way beyond my expertise. Wish I could help, but I might give you the wrong answer.
