Firstly, you are so beautiful! I'm so jealous 
Also, great tips. Unfortunately my skin is so disgustingly scarred and sensitive to 99% of make up out there that I can never look great. My make up is always obvious, my foundation is always a little too "orange" even though I get the absolute whitest/palest foundation. I wish that I could use different types of creams, powders, foundations, primers. Nothing ever looks good on me and I end up breaking out so bad. I do love the eyeliner tutorials tho!
Well firstly, thank you so much! And secondly, you are too hard on yourself! You look absolutely gorgeous and although acne can make us feel awful about our appearance, what we think we look like is not usually how we look to other people- if that makes sense! So try not to let your skin get you too down. Easy to say, I know!
It must be really hard having such sensitive skin as it always feels like such a risk trying out new things. My skin is very prone to rashes, redness, acne etc but I've never had any sensitivity to that lancome Teint miracle foundation, so it might be worth a try for you- but you know your own skin and I know sometimes it's safest just to stick to what you know.
Otherwise, if you aren't already, start taking some vitamin D3 supplements along with zinc and magnesium. I keep banging on about it but it really has done amazing things for my acne.
Oh and thanks for checking out my blog- if you love eye makeup, I've just discovered the most amazing mascara/ lash extension product ever! That sounds like a lot of hype, but honestly i'm so impressed with it, so I've just posted a review on it.
