Why One Truth 818?

It's Not Just Theory — It's Tested

Skincare is full of bold claims and thin evidence. One Truth 818 took the harder, slower path: an independent 30-day clinical trial conducted at Abich Laboratories in Italy on 100 volunteers aged 36–65, using objective measurement tools (3D skin scanning and cutometry) rather than self-reported impressions.

The results, after just 30 days of twice-daily use:

Wrinkle depth reduced by an average of 11–14% (crow's feet and forehead)
Skin roughness reduced by 9.6–12.5%
Skin firmness improved by over 20%
Elasticity improved by over 8%

Abich Labs concluded the results were statistically significant — a rare standard in an industry where "clinically proven" often means very little.

TAM-818

TAM-818 is a patented telomerase-activating molecule developed by telomere biologist Dr. Bill Andrews at Sierra Sciences. Telomerase is an enzyme that can re-lengthen telomeres, keeping cells biologically younger for a longer period.

What makes TAM-818 different?

Most anti-ageing skincare focuses on reducing the visible signs of ageing at the skin’s surface. TAM-818 is designed to support telomere health by activating the telomerase enzyme, targeting a biological process associated with cellular ageing. This innovative approach aims to support skin health at the cellular level, going beyond traditional surface-based skincare.

Who Can Use This

If you're between 30 and 70 and you're starting to notice that your skin doesn't snap back the way it used to — that fine lines are becoming creases, that your complexion has lost its glow, that texture feels rougher and hydration doesn't hold — this is the product designed around the science of why that's happening.
It's also ideal for anyone who has over-relied on lasers, peels, or injectables and wants to give their skin a genuine reset — supporting its ability to function and repair from within, rather than adding another layer of external intervention.

Revolutionary skin care products

I just love using my One Truth skin care products. They're quickly absorbed and very gentle on my sensitive skin.
I feel ten years younger and look more relaxed since using the One Truth serum.

One Truth 818 products

Vitamin C has brightened my skin, the serum has lifted the area around my eyes so l nolonger look tierd. The marionette lines hve softened. I have always looked younger than l am but these product have enhanced my more youthful appearance. I am 78 and have worked in offices so that has protected me. I just budget for these products now.

The Trio - One Truth 818 Serum, Atomiser & Cleanser 50ml

Fantastic

Brilliant pump dispenser. Easy to get all serum out especially at the end so no wastage. By far my favourite dispenser design. 818 works. It is that simple. Nothing else is needed.

One Truth 818 Serum Pro 250ml - *LIMITED STOCK AVAILABLE

Wonderful serum

The serum is very light and velvety, glides on and absorbs quickly.
I’ve been a little bothered by sagging skin in my lower face that has been worsening in the last few years, but the serum and atomiser have definitely turned back the clock and made my skin look more firm in this region. The hooding on my eyes has improved a little as well, so I look less ‘tired’. I haven’t done anything else differently, so I’m putting it down to these products. I’ve been using the serum (and atomiser) for about 9 months and although the texture of my skin improved initially, it took a several months more for the sagginess to improve. Several people have commented that I don’t look 60 so I’m pretty happy about that.

One Truth 818 Serum (50ml)

My Truth of One Truth 818

The products are wonderfully refreshing and luxurious for my skin. They have maintained my skin's health and appearance, for which I am grateful and happy. The investment however is significant and would be my only cautionary comment. If I am to suggest a future product, it would be one that addresses the ravages of eye bags, puffiness, wrinkles, and darkness. Thank you for the delightful and effective products.
