I don't think I would use this product under foundation or that you should. It might end up leaving you oily, or mess up your makeup. It is more of a treatment for night.

I only wear this at night because it makes my face kind of oily and stings a little so I wouldn't recommend wearing this under foundation.

Use this after moisturizer. It does not replace primer but can be used under foundation. I hope this answered your question.

I'm not sure I would double up on retinol products. Maybe do a test patch on your jawline to see first.

I'm no dermatologist but I think it depends on how much your skin can tolerate...everyone is different. For me personally I think it is pretty mild yet very effective. If you start using this product maybe give it a few days in between and then just this one and stop the other one, don't double up right away. I say this for a couple of reasons: 1. It might be too much and 2. If you do see a change it may just be one product working and the other is not. Then combine them after a week or two. Do it gradually.

i combine this with the murad anti acne anti wrinkle serum and have not had a problem with over drying my skin. if you use less while combining it with retinol it shouldn't be a problem. maybe get a sample of a retinol and do a test run for a few days to see how your skin reacts?

Before I started using this, I was using the Exfoliating Treatment Gel as well. Essentially, they are both gel treatments targeted at oily and acne prone skin. The only difference is this product is targeted more towards combating oiliness, rather than treating breakouts/acne. I too prefer this product over the Exfoliating Treatment Gel :)

I was using the acne and wrinkle reducer treatment and switched to this. I think it works better. It still keeps acne at bay--I actually think it works better.
I also use the Time Release Acne Cleanser and the Antiaging SPF or Mattifying moisturizer during the day. They work really well. :)

this is just a more gently version of the exfoliating acne one...but also has retinol that is a preventative,increases cell turnover the more you use it which you want the older you get

I think this product will HELP, if you use it over time. It won' work right away... but it has the glycolic acid in it.

A peel.... like the pumpkin one by Peter Thomas Roth, or the Enzyme Peel Mask by REN, those have been suggested to me by sales associates/advisors at Sephora stores...for blackheads and breakouts (healing.)

I hope this helps!

I have both the dermadoctor blackhead and this and I think this one works better, plus you get more for your money. Honestly, both products have similar ingredients so they work similar, but I think the murad one works faster. It's also better at preventing blackheads and acne.

I only use this gel once a day, at night. After I wash my face... then I put moisturizer on to make sure not to dry my face out.

I use this at night after cleansing and moisturizing. It might help fade spots since it exfoliates the skin to reveal new skin.

i am 23 and suffered from cystic acne when i was out of high school. you defiantly need to find the right products for you a long with a good diet and lots of water. anything with benzoyl (not sure of spellimg) peroxide really helped to dry out my pimples but dont go for the strongest percentage start of light and work your way up or you will end up doing more bad than good. find a great cleaner that works well for you and then apply a good benzoyl mask to help kill bacteria and dry out acne and also i was on an antibiotic and that really improved my skin, hormones can also be effecting your skin. DONT PICK them i did and now suffer from acne scars! So try out whats best for you

I know you might not want to hear this, but take it from someone who is much older now, and had terrible acne as a teenage & young adult - I was on accutane 3 different times if that helps make this believable. It's your diet - you need to cut out all sugar and processed foods. You will not believe how quickly your skin clears up when you stop eating junk! The skin companies will have you believe it's their products - is up to you what to believe.

It's worth a try !

I have the same issue and have been using this for months. I didn't notice a change in the size of my pores, of in the amount of blackheads.

I have used both the exfoliating acne gel and the T-Zone pore refining gel. I am partial to the T-Zone gel. In the beginning, I tried to use both at the same time....take my advice, DON"T DO IT! It will burn your face off! Both products sting when applied, but for me the stinging never went away after applying the exfoliating acne gel. I must have had an allergic reaction to it and it irritated my neck so badly that I had severe burns! I would suggest, if you don't have sensitive skin that is, that you only use the T-Zone during the day and the exfoliating acne gel at night. It is pretty intense if you have sensitive skin. Hope this helps!

much prefer the exfoliating acne treatment gel. this is over sticky and I didn't notice any difference with acne---the acne treatment gel smooths the complexion and really prevents breakouts---didn't overdry either.

This gel works differently... slowly. The exfoliator works as a wash instantly. This P.R.G. works over time, and you notice results get better week by week. An esthetician can answer this question better or more in-depth!

You could use the acne treatment one night, and then rotate the tzone pore refining gel every other night.
