M2 Skin Technologies HP Skin Refinish is not for my husband

Reviewed by Marta August 19, 2009 13 Comments
M2 Skin Technologies HP Skin Refinish ($44.50) is a gel that it is so sticky that it stays sticky for hours on end. It made me feel like human fly paper. Given that M2 smells like rotting fruit, I'm surprised that I didn't actually attract any insect life (although now I come to think about it, the Truth In Aging office did have an invasion of tiny ants the other day). It's supposed to be worn at night and I can tell you that this did not go down well with the man who shares my bed.

There has been quite a bit of (self-generated) buzz about M2 Technologies and HP Skin Refinish is sold out on, so maybe it's just me (and him). The main ingredient is mandelic acid and, although billed as antiwrinkle, it is primarily antibacterial and was used for most of the last century to treat urinary infections. More recently it has been found to be useful against adult acne. In fact, it is an alpha hydroxy acid that comes from almonds and is supposed to be stronger while being  less irritating than glycolic acid. The only research I could find on whether it does, as claimed, reduce wrinkles was conducted by the doctor who discovered retinol and who now sells mandelic acid in a potion called MaMa Lotion. Like MaMa Lotion, HP Skin Refinish also contains malic acid - another alpha hydroxy acid, this time from apples.

HP Skin Refinish has quite a few other things going for it: a couple of marine antioxidants, ubiquinone and aloe. I am less keen on the potassium hydroxide, a pH balancer or buffering agent. The European Union classifies potassium hydroxide as toxic or harmful and limits workplace exposure. The severity of the effects depends on the concentration and the length of tissue contact time.

I'd love to hear from anyone who has tried M2 Skin Technologies HP Skin Refinish and whether they had results other than a peeved husband.

    Oh yes, M2 skin refinish!! It's sticky, I agree - I apply it after cleansing, let it sit for 20 minutes or so, then top it with a few drops of passion fruit oil that I buy from - I can't live without oil, by the way. I wake up with skin that's so smooth, I can't believe it. I switch off every other night between M2 and Retin A. I cleanse at night only, with a mix of 65% sunflower oil and 35% castor oil. A couple nights per week I follow that with a cleanser, usually Neutrogena acne wash. I just splash my face with water in the morning and apply vitamin C serum mixed with SPF 30 sunscreen. I'm looking for a new subscreen, now that Aveeno has discontinued their Continuous Protection line. The new Protect and Hydrate stuff is awful - balls up as soon as you try to apply anything over it, including makeup. But hey - that's another post, right?

    I just started using the M2 20% HP Skin Refinish. I use a small brush to appy the lotion. It helps me to control waste. I have noiced that when I apply even thin layers to my skin it helps to dry he lotion quicker.

    I am hoping to reduce my dark eye circles along wih evening out my skin tone.

    My dermatologist in the Philippines introduced me to M2 HP and just after 3 weeks my Melasma is gone, the open pores on my skin is shrinked and my wrinkles smooth out. This is a miracle. It's sticky but well worth it. My skin turned flowless and i look younger everybody is asking me what am I using.

    Leslie, happy you followed up with your final thoughts on M2. Being a woman of excess, I was able to finish my bottle in the 2 weeks I designated for continuous use. Between being stuck to my pillows and feeling like my skin couldn't breathe, I swear the M2 was waking me up at night (I can sleep thru a herd of elephants coming into my room) so this is unusual. Yes, it does exfoliate, but the results aren't worth the discomfort of wearing it or the lack of sleep either. I won't be buying this one again.

    I agree, the stickiness took some getting used to and almost made me return the product. Since my last review I've been using the Refinish every night and have continued to have good results with my skin tone. In fact, a large freckle that appeared on my check a few years ago is nearly gone! However, I have noticed my pores are more clogged and larger than usual and am not sure what the cause is. While the Refinish has done it's job for the most part, I'm going to try something new when I'm finished with this bottle.
