Don't let the price point throw you off. I have been a Retin A (Zianna) user for years coupled with hydroquinone at night. Because I am diligent the brown spots I have are not very noticeable with or without makeup. But I notice them. I have used a myriad of "antioxidant" products, moisturizers, serums, etc. This stuff is amazing - and the results are obvious. It did not sting or bother my skin in the least but I have noticed a distinct improvement in the texture and discoloration. I put it on in the morning after I wash my face. I've been using it through sample sizes for a month and I just plunked down the $150 for it yesterday. Happily. Give it a try. You won't be sorry.

Love it!

i use this every morning after i cleanse and tone. I apply 5 drops onto my dry face. I use one drop for my forehead, one for each cheek, one for my chin and nose and one drop for my outer eye orbital bone area. I really like this. I used to use the SkinCeuticals Serum 15 AOX but now i am using this because it is supposed to be more effective at protecting you from a broader range of damage. It is also better for my oily skin. I have extremely fair skin that i like to keep protected from the sun in hopes that i can look great and creamy when i am old instead of liver spotted. I have oily congestion prone skin and this SkinCeuticals Phloretin CF is the best for it. If i had dry skin i would mix or switch off using this with SkinCeuticals C E Ferulic. This vitamin C serum is really very light and disappears into my skin which i like! i do not like to feel things sitting on my skin.

I use the M2 Skin Recovery Moisturizer in tandem with the M2 Skin Refinish 20%. these products have made such a huge difference in my skin! I love mandelic acid for clearing out my pores and killing germs. I have oily congestion prone skin and i do not really need the extra moisture from this M2 Skin Recovery Moisturizer but i do buy it and use it 15 minutes after i use the M2 Skin Refinish 20% to take down the stickiness i get from that serum and because i know they work in synergy together.

I use this serum at night followed by the M2 Skin Recovery Moisturizer. This has made such a huge improvement in my skin! it is strong and effective without me having irritated skin. The only negative about this serum is that my skin feels sticky when i use it. but following up with the M2 Skin Recovery Moisturizer after 15 minutes takes away the stickiness. I do not think i need the extra hydration of the M2 Skin Recovery Moisturizer and i mainly use it to take away the stickiness i feel from the M2 Skin Refinish 20% i have oily congestion prone skin that really needs help staying clear and killing any germs and i feel like this does both of those while i am sleeping.
