Details & care
What it is: A hydrating liquid serum that targets skin elasticity to sculpt and firm the skin for a younger-looking appearance.
What it does: Formulated by Dr. Yannis Alexandrides to improve elasticity and skin density, visibly refined pores and reduce the appearance of wrinkles. The Black Diamond Serum is powered by a potent microalgae extract that helps lift and tighten skin due to the elasticity that occurs naturally as the result of collagen breakdown. Facial contours appear more defined and age spots and wrinkles diminish thanks to added NovoRetin, a natural form of retinol suitable for sensitive skin.
Key ingredients:
- NovoRetin: a powerful botanical extract that lifts and tightens lax skin
- Fine black diamond powder: gently exfoliates to deliver active ingredients effectively and deeper into the skin
- NAC Y2: a trio of actives with superior antioxidant capabilities that harness the power of glutathione, vitamin C and escin to boost the body's natural ability to repair its cells at the deepest level
How to use: Following Vitamin-C Brightening Cleanser (sold separately), distribute 1-2 pumps between fingertips and apply to face and neck in an upward motion every morning and evening.

Hands down the best serum ever
Not gonna lie, when I first saw the price of this serum I thought no way, too much....but I had a sample in hand and didn’t want it to go away so apply it I did. It took one application for me to notice my skin was brighter, tighter and looked more revived, I was hooked. This serum is now a staple in my routine. So glad I didn’t judge a product by price and walk away from what is now my go to skin care favorite!

Decent enough
Received a couple of 10mls of this in various gwps. It's a decent enough serum but not at all worth the money. Gives good hydration, is gentle and has a pleasant scent. I liked it paired with the black diamond essence by the same brand. Reminds me a bit of the Dr Dennis Gross DermInfusions Fill Repair Serum which is more affordable. Won't buy but I'm happy I got to try it.

Pricey but hardworking
My eyes nearly popped out my head when I saw the price of this serum. I had been using a small tube I received in one of the beauty gifts and actually it lasted me longer than I would have expected so a little goes a long way. My skin has looked plump and glassy on days I have used this, and it even helps reduce dehydration lines after a night out. If money were no object…

Good
I received a small sample of this with purchases from the other range. I like this serum. I felt it improves completion and appears to reduce fine lines. I have sensitive skin and there was some purging or dryness after use but I felt it was working nicely to rejuvenate my cells. Price point is very high so unlikely to purchase myself. Sample lasted quite a while when not using everyday.

Nice Serum
I received a generous sizes sample of this serum which lasted about 5 weeks. I use a number of Skin 111 products so was keen to try this. I have mature sensitive skin so am always cautious with new products. This serum was lovely it reduced fine lines and left my skin feeling hydrated. The serum is well absorbed no lasting residual and I was able to apply my foundation almost immediately. I would love to use this on a regular basis but unfortunately the price point is prohibited for me.

Loved it
This serum made me feel better. I noticed a difference after using it for 4 weeks (which may be quite long) but you just have to trust the process on this one. It diminished the size of the my fine smile lines, which is exactly what I was hoping for when I purchased this product. So I would recommend this to someone as it did what it says.
