It is easy to get overwhelmed by all of the ideas and tips that we find ourselves inundated with. Pick one thing to ingest in 2018. Maybe you never take your multivitamin, maybe you don't drink enough water, maybe you want to start taking collagen or fish oil to improve your skin. No matter what you choose, any of these and countless others will reap beauty benefits. Don't stress yourself out with a million new things to take or drink; just pick one and see if you can stick with it. Once you start seeing results, which will likely be in a few weeks, you won't want to stop, and the rest of 2018 is in the bag.
I personally plan to take Olly Undeniable Beauty Grapefruit Glam Vitamin Gummies (£14). I don't know for sure that they will work, but if they are good enough for the Kardashians, they are good enough for me.
