Gagagran in over 40 years I've never thrown out makeup I'm likely to use and think it's a sales ploy to tell us to throw out products after a certain time. Before I discovered tubing mascaras (Holy Grail stuff and no more panda eyes), occasionally I might find a mascara had dried out and chuck it, but not much else. I use common sense to decide if a product is no longer usable. Every now and again I have a clear out and offer it to to my Mum first because she gets through makeup much quicker than me.
If your foundation turns orange, or maybe one or two shades darker on your skin, it's because it has oxidised with the natural oils in your skin. The only way to know if a foundation won’t oxidise on you is to try it before you buy it. Ask for samples or test it at the counter and then wait at an hour (or two). If the foundation has changed colour and looks darker, try a lighter shade. If it looks orange or looks darker, you could try using a primer because it creates a barrier on the skin so that your sebum won’t react with the foundation. This doesn’t work for everyone, but could be worth a try.
At the end of the day the LFF video is selling its products and it's target audience is mature women who are not confident with makeup. The model does look lovely
, but I think the eyemake up is too dark for her beautiful eyes and the video doesn't include any close ups - that would be a deal breaker for me because I want to see the finish on the skin. Plus I agree 12 products is unreasonable for makeup unless it's a really special occasion. I definitely don't think it's worth paying extra for its products, not when there's experts out there like Lisa Eldridge (see my previous post for links) who do much better makeup tutorials. If you go to a beauty counter for a makeover, remember the assistant wants to sell you the products, so make sure you tell them what kind of look you want e.g. everyday, evening, special occasion. Just my opinion of course.
Personally on a day to day basis if I'm leaving the house, all I want is to have more even toned skin because I have a very ruddy complexion and combination skin (oily and very dry). I also have sebaceous hyperplasia and the bumps can look like pimples, so I don't have nice skin.
After leaving my moisturiser to sink in, I use Garnier's BB Cream Miracle Skin Perfector in Light as a foundation and apply it in a dabbing motion with a damp beauty sponge from Real Techniques. It's the only technique I have found that doesn't make foundation settle into my pores. It doesn't give full coverage, but does give my skin a nice finish. It can easily be layered for more coverage or touched up. I have lots of face products
, but end up go back to the Garnier BB Cream for an every day look.
To complete my 'every day' look, I use mascara and a chunky lip pencil. At the moment I'm using Revlon's Just Bitten Kissable Balm Stain in Honey and DHC Mascara Perfect Pro Double Protection (only available by mail order). Three products and I'm good to go.
I add other products when I feel I need to or want to make more of an effort. For a more full coverage look I use Clarins Instant Smooth Perfecting Touch Primer (samples from eBay) with Revlon's ColorStay Foundation For Normal/Dry Skin and Rimmel's Sun Shimmer Bronzing Powder in Light Matt to add back colour and shade.
