Just gonna put it out there: I've never been much of a believer in the supplement industry. Mainly, because that's what it is, an industry. One worth around £670 million at that. However, whilst I'd love to pretend that it was my innate distrust for 'the man' and big pharma that put me off popping every pill that offered to make me thinner, healthier or less likely to catch a cold – really, it's laziness, plain and simple. I've tried, but after the first three days of committing to whatever wonder-supplement currently doing the rounds, I give up, forget, then shove them in the back of my cupboard.

But no more. On the grapevine (ok, I was earwigging at the gym) I heard about a product called Lumity, an anti-aging supplement supposed to work wonders on skin – even if you're not – you know, old. This was back in March, when as well as getting to grips with a new job and training hard in the gym for a trip to Ibiza in May, I was also out almost every night with work and friends – and boy – did it show on my face. Spots had started to cluster where once there were none, there were patchy bits of red (a sign of stress, I was later told) on my cheeks and neck. I looked… tired. Older than my 30 years. So, with renewed willpower, I signed up for a three-month trial. Here's what happened.

In the interests of fairness, and to make sure I actually took the things, my conversion to supplement scoffer started with a skin scan, which I then had every month for the three month trial. Everything from elasticity, to collagen levels, how hydrated my skin was and my TEWL level (it stands for Trans Epidermal Water Loss – basically the rate at which your skin loses moisture) were measured. My first results showed that my skin was dehydrated and the collagen levels on my right side weren't great, probably the product of a latent tanning obsession.

This was a picture taken that day – the black dark areas are fat, and the red and yellow dots are collagen fibers. Basically, the more black areas there are, the more depleted your collagen.

There was work to be done. I embarked on my challenge immediately.

Lumity is made up of two sets of tablets: the morning supplements (which contain a mix of Vitamins A, B, E and C, selenium (a known anti-ager), turmeric root extract and flaxseed oil for healthy cell membranes), and the evening ones, which with their mix of potent amino acids, are supposed to help you sleep better and for longer, as well as provide your skin with all the nutrients it needs to heal over and renew overnight. You take four of each, twice a day.

I'm so bad at remembering to take things, I had to set alarms for the first two weeks to remind myself, and leave the tablets next to my toothbrush so I was visually prompted each morning and evening. It worked, and eventually it became habit.

I'd been warned that the effects are cumulative so I wouldn't notice much of a difference for the first month, but in my second month of taking them, the magic started to happen. Firstly, my spots disappeared. Even the hormonal ones that come up in the same place each month – gone. Second, and this is where I sound like a total wanker, but my skin had more of a… glow about it. It was like I was walking around with a permanent layer of Touche Éclat on my face.

At this point in time as I said, gym-fever had properly set in, as I squatted, lifted and spun myself ready for a three-day hen-do in Ibiza. (The threat of daytime pool parties will do that to a girl). But by the end of this second month, my early morning HIIT sessions weren't nearly as painful. One of the other welcome effects of these supplements, which even those not interested in anti-aging should heed - is that it can improve energy levels. It's also supposed to nix food cravings, but I can't say I noticed that one bit – as the sheer volume of Quavers I ate in this period will attest to.

The final month of my experiment is where everything clicked into place. I never forgot a dose, could comfortably go to work without foundation and had skin that felt tighter, more toned and more even that I'd ever had before. In my final skin scan, my results showed the following:

Elasticity had improved by 4.8%

Hydration had increased by 22%

Collagen had improved by 10.3%

And TEWL changed by 5.17%

A picture is worth a thousand words, and by the end my scan had gone from this:

To this:

Not bad for popping a few pills.

At 30 years old, I thought I was still too young to benefit from an anti-aging product, but it turns out I'm not. If you're fed up of not knowing which cream or serum will really help your skin, I'd definitely advise trying to change it from the inside out. I've gone from supplement sceptic to a (relative) convert. Not all pills are created equal, but when it comes to this one, I'm sold.
