Question for those with skin/make-up knowledge.

Take her to Sephora or Ulta. And make sure she keeps up with her skin care routine when she wears make up. She needs to remove all her make up before she starts cleansing and washing her face.

You might want to look for an oil-controlling primer to use before the foundation.

Also, make sure her brushes/sponges are clean.

As someone who also used to have oily skin, I 3rd Clinique. A very good drugstore option is Revlon ColorStay.

I always liked clinique...right up until yesterday. I should say that it is just the one clinique lady at the one counter, but dang. She made me feel like poo on a stick because I very nicely asked for a moisturizer that doesn't have sunscreen. They make it, so I know that other people ask for it too, but she gave me the full on stink eye and a five minute lecture on why I am wrong in not wanting it. I live in Florida, I get the need. I really do. But...the fact of the matter is that amount of moisturizer you use doesn't have the amount of sunscreen you need for it to be effective. Not to mention the fact that in order for sunscreen to be at it's maximum efficiency, it needs to be reapplied every 80 minutes or so. By the time I leave my house, 45 minutes of that has already elapsed-it doesn't last all day. I wear sunscreen faithfully when I am outside for any length of time, and usually a hat, but goodness, to lecture me?? No thank you. (apparently my vent of the day. lol)

Anyway, I am going to say in spite of my major irritation with the Clinique lady yesterday, I would head that way. They are generally really good with people and they have great products for teenagers.

I also want to reiterate the need for moisturizer.  My skin does so much better when I moisturize daily. 

Several Youtubers that I watch have oily skin. I linked a video below that's from a Youtuber I watch. She has a drugstore and a high end foundation recommendation video too. I like her foundation routine in the video I linked. 

I would go to Sephora, that way you can try samples, before investing in the products.

Some of the staff knows a lot, and some don't and only recommend what they like or have used. Ask to speak to a skin care specialist.

I went through some trial and error, and tried many samples that didn't work for me. One day, I talked with an extremely knowledgeable staff member, who inquired what I do in the morning and evening as far as skin care routine, what I was wanting to achieve makeup wise, what my problem areas are, and what have I tried and didn't work. Based on that, they made recommendations and gave me samples. Those recommendations were awesome and I finally found skin care and makeup that works for me.

Be patient, sometimes it's trial and error, because what works for one, may not work for another.

One of the problems with drugstore cosmetics is the chemical warfare on your face that can ensue. Some product lines put their acid neutralizer in the toner, others in the moisturizer, others in the foundations. The same with other aspects of make up like anti oxidants, retinal and other active ingredients. Once you determine a skin care regime, it should be the same if you are wearing a foundation and other cosmetics or not. You skin needs taking care of. Like others have mentioned, if you have oily skin and skip moisturizers, then the skin works overtime to replace moisture and gets oilier. My daughters had the hardest time believing that.

Figure out what she is going to go with and stick to it for at least a month to determine if it is going to work or not. Once you know what you are going to use, THEN you can go to the drugstore or WalMart and pay less for it. If she gets a makeover and follows the recommendations given she should be able to return the product if it becomes a problem like a rash or wrong color whether she goes to a Clinque counter or to Ulta.

We went to Sephora and they have these things that they held up to her face to match her skin tone to a foundation. It was great! I am terrible at matching colors, and as expensive as foundation can be to keep buying it to find the right color, Sephora was worth it!

My daughter also had acne (I never had it as a teen, but her dad did), so she went to a dermatologist, and finally after a year and a new doctor, they got it right! When she was at college, her face cleared up, but when she came home, it would break out again. Her dorm was very old, and we joked that their water must be good for skin!

maybelline fit me matte and poreless foundation and setting powder i live where it's hot as hell and that is the only thing that hold up on my oily skin. Also pick her up blotting sheets they will save the day. You can try a oil control primer as well.
