MDFactor Face Serum – Anti-Aging Face Serum with Vitamin C in L-Ascorbic Acid Form for Face & Body – Ideal for Fine Lines & Wrinkles Removal, Dark Spot Reduction & Collagen Production

This is the best Vitamin C serum you can find. I have been diligently using the serum on a daily basis even when I travel overseas. It moisturizes my skin, prevents my skin from sun damage, diminishes fine lines, deceases the dark pigmentation from sun spot, and gives my skin a shiny look. I will give 10 out of 5 stars. I have not found any vitamin C serum which can compare with MD factor for the price I invest.

The plastic safety seal is only on the bottom of the glass bottle and does not cover the dropper top so in other words, the dropper can be removed without touching this supposed safety seal. Perhaps it has been tampered with as it is unknown because the safety seal is incorrect. I checked two bottles and found both to be unsafe.

What I received already had the top off the seal around the bottle pealed off -has been opened and is leaking out the rubber dropper gasket.About an inch of liquid missing in the bottle, and it's not that it leaked in the box =so I can only guess someone used it - didn't seal it quite enough - returned it.And it was then sent to me.If these were 'normal' times - I would have tried it anyway.But there not - so I won't be able to say much about the product.> Except to say it's an odorless - thin - sheer serum.Feels oily on the fingers - doesn't have any fragrance that I can tell.Can't speak as to if it soaks in well - leaves a residue - or is beneficial.>>> Directions - Clean face - dry - apply a few drops to face / neck / hands( avoid eyes & open cuts ) twice a day.>>> This may be a 5 star product, but I can't vouch for thatand reason for 1 star

This is way too oily for me to use during the day, and I have dry skin. I can't stand the feel of oils on my face. Good ingredient deck.

Do I think this is a bad serum? NoDo I think it is excellent? Also no.So far, I think it is okay. I haven’t noticed any amazing results, but I think I need to use more consistently and pay closer attention.This is the first vitamin c serum I have used that feels oily. It isn’t excessively oily so doesn’t bother me, just an observation. It feels like a thin facial oil that absorbs well. It feels moisturizing. There is no detectable scent.The packaging is very plain and boring compared to others I have used. This is fine, but it is rather expensive, so I was surprised to see such a boring bottle. It is a dark glass with a dropper lid which is nice.My major complaint about the packaging is that it arrived feeling oily on the outside. I could tell some product had leaked out somehow- not cool especially considering the price. Also the product was poorly sealed. The plastic to seal covered the glass bottle and didn’t extend up to cover the dropper. Someone could easily have tampered with this.Both those issues should be fixed as it doesn’t seem to be an isolated incidence. I did see some other reviews mention the same thing.Overall, I like the way the serum feels on my skin, but haven’t noticed any real changes other than maybe my skin feeling somewhat moisturized after using. I haven’t had any irritation from using on my sensitive skin.I’m going to try to use this very consistently and regularly for awhile to see if I notice anything as I do have some dark spots that I would love to be gone. I’ll be sure to update this review if any issues arise or I have comments to make. As of now, this product seems fine, but is not a good value for me at all for the price since I haven’t noticed results.I hope my review was helpful in some way, and if so, I would love to know-thanks!

I have been a regular client of MD Laser & Cosmetics for over 10 years. I am a local client and have been able to make purchases from their physical office in the SF Bay Area. Lucky for me now that the vitamin C serum has made its way to Amazon which makes purchasing more convenient. The vitamin C serum is an excellent solution to maintaining glowing and well textured skin. I love it and highly recommend it.

MD Factor vitamin C serum is one of my favorite skin products and I have been using this exact one over 5 years! I use it twice a week at bedtime. At first it tingled and then I found out I had been using too much, now I apply just a couple of drops and it doesn't tingle, yet it's still enough for my whole face, neck and décolletage. I have noticed my skin is so much softer and overall my complexion looks more youthful - this is one of my top 5 favorite skin products!!

This product may work well, it's so hard to know because I didn't see any dramatic results. I do think it may have lightened some sunspots, and it didn't make me break out so I'm inclined to say it works well. At the very least it didn't do me any harm. I wouldn't call it a serum, it's an oil, one hundred percent. It doesn't absorb into the skin very well but stays oily for some time. It works great if you use it before putting on skin food moisturizer (if you use that you know how greasy and thick it is).The packaging is one of the worst I've ever seen, it came looking like some of it had already been coming out of the bottle, which in fact it had! It was greasy and as you can see from my image, all the white text that was on the bottle has started to come off! How this is possible I do not know. I still have used it on my face though because like I said, it seems like it actually might be lightening my sun spots. Maybe improve your packaging.
