This groundbreaking cream-serum uses a powerful retinaldehyde formula to dramatically improve the visible signs of ageing.

Medik8 Crystal Retinal 1 is Medik8's entry-level gentle-strength vitamin A, ideal for those who have really sensitive skin or are looking to incorporate a low strength but highly effective vitamin A serum in their routine.

Benefits of Medik8 Crystal Retinal 1:
  • Renews & resurfaces the skin
  • Visibly improves the appearance of fine lines & wrinkles
  • Works 11 x faster than other types of Retinol
  • Suitable for all skin types
  • Clears the bacteria responsible for blemishes & breakouts

This groundbreaking cream-serum is formulated with 0.01% Retinaldehyde, a super-charged derivative of vitamin A, which works to promote the skins natural collagen production, rebuild lost collagen and increase cell turnover, promoting a smoother, brighter and healthier complexion.

By requiring only one conversion to retinoic acid, the Crystal Retinal™ works 11 x faster than other forms of retinol, delivering results comparable to clinical-grade vitamin A. Trials have shown that in as little as four weeks, users have seen a vast improvement in the appearance of pigmentation, fine lines, wrinkles and breakouts and have an overall improved complexion. With the innovative crystal encapsulation system, the Retinaldehyde is slowly time-released, helping to reduce irritation, making this suitable for all skin types, including those who have previously been sensitive to Retinol.

With other key ingredients including Hyaluronic Acid and Vitamin E, the skin is hydrated at every level, leading to a plumper and smoother complexion and the skin barrier is strengthened, helping to lock in moisture. With a lightweight, silk-like texture that absorbs quickly into the skin, this powerful serum renews and resurfaces the skin, visibly minimises fine lines and wrinkles, reduces blemishes and pigmentation and delivers a healthier, brighter and more even-toned complexion.

Medik8 Crystal Retinal 1 key active ingredients: 

  • Encapsulated Retinaldehyde –Proven to work up to 11 times faster than retinol, retinaldehyde is a revolutionary new form of vitamin A that targets fine lines and wrinkles, pigmentation and uneven skin texture. 
  • Hyaluronic Acid –With a unique ability to attract and retain more than 1,000 times its own weight in water, hyaluronic acid draws moisture from the surrounding atmosphere into the skin, leaving the complexion feeling both nourished and supple.
  • Vitamin E –An oil-soluble antioxidant, vitamin E can quench free radicals on the skin while stabilising retinaldehyde for optimal power. 
  • Glycerin –As a natural humectant, glycerin traps water within the skin to leave it hydrated and comfortable.

How to use: 

To be introduced to the skin gradually. Use once every three nights for the first two weeks, increasing to every other night for the next two weeks.After this point if the skin is not showing any signs of dryness or sensitivity, increase usage to every night for best results.

On an evening, on dry skin, blend a small amount over the face and neck before following with your regular Medik8 hydrator.

Can't Copy Carhartt
Color: Carhartt Brown (Bifold), Color: Carhartt Brown (Bifold)
I just received it but I like it so far. Replaced a 12-year-old Carhartt wallet that didn't have RFID protection. Mink oil turns it into a pleasing chestnut, FYSA

Overall a nice wallet
Color: Carhartt Brown (Trifold)
The card slots are a little tight so removing cards can be a hassle. On the other hand, cards won’t fall out if you invert the wallet. I expect the card slots to loosen up with prolonged use. The wallet is great in all other respects.

Compared to g-shock?
Color: Black/Yellow
Firstly random public reviews can be comical…”it’s has a battery, terrible, One star” or “I don’t like yellow, one star” omg peoples do better. I’ll review this while comparing to an older style of g-shock from the same era. I’ll start by saying this timex rocks, for me in my mid 50’s it’s so retro and nastalgic, brings back memories, I may have even owned this model back in the day. What’s great about it- the display, larger digits than the typical g-shock and they are super crisp, clear and easy to read. The indiglo is awesome. This is the most accurate quartz watch I have aside from the atomic g-shocks that adjust themselves daily. I prefer a chunky watch and the g-shocks do a better job in that department. i feel this watch is rugged, but I’d still give the nod to g-shock in this department. 200M water resistance is the gold standard and this watch has it which I love for peace of mind for any water based activities. This is a 5 star watch at a great price. I still love some aspects of a g-shock better but its just preference.

Everybody loved the high-tech style and amazing functionality
Color: Black/Yellow
I'm not a Timex fanboy, and I've had my fair share of problems with the Expedition line, so this review is my honest opinion as a man who's worn Armitrons and Timexes since I was 10. I remember in 1992 when the Timex Ironman Triathlon with Indiglo was first launched - My older brother got one, then me and my neighbor friends. Everybody loved the high-tech style and amazing functionality. Even Bill Clinton was rock'n this watch, for those who don't remember. Quite simply, this is the perfect watch at a great price, in my opinion. Perfect as a gift for any man, and I think the original black/olive drab/yellow coloration is still the coolest. In this day and age of smartphones, it still pays to have this watch. The alarm is less annoying sounding than a cellphone, and doesn't wake up the entire house. To turn it off, just tap the watch, no more reaching for the phone or alarm clock. Timer comes in handy for anything; timing my kids' timeouts when they get in trouble, 15 minutes room clean-up times, etc. Chrono is fun for anything you wanna use a stop-watch for. I set the second time zone for Vietnam time. It really is a million times easier to use this watch for all of its functions than reaching for a smartphone or alarm clock, etc. If you;ve been relying on your phone for a few years as a watch/chronograph/timer/alarm - you'll be so glad you finally got a watch like this. I've never tried a smart-watch, however I feel those are not as necessary,durable or practical as a real watch. Other Timex watches I've used were freakin' trash - couldn't throw em away fast enough. Might as well open the box while holding it over a trash can, so the watch can fall right in when you open the box. That's my experience with the Expedition line-up. Back to this watch: The only thing I wish this watch could do is measure activity thermogenesis (calories expended throught the day) or work as a pedometer, which some smart-watches and other devices can do. I also cannott decide if I like this new, slightly larger, heavier/thicker design of the Ironman Triathlon over the 1990s design. The 90s models styling was "tight to death'. Star-split buttons were seperated. The mode button was yellow. Overall more compact and bi-cultural;by that I mean it looked great as an athletic watch or a politician, business man wathc. This new model is bigger, better ingress/shock resistance, and more of an athletic style over all, and is a little less colorful. I almost went with the G-shocks, but they still just look like crap and are waay to expensive. Sure, they have some better features, can survive WWIII, but I am a traveler. I need a watch that can work in the dark in any environment. The G-shocks are often using some kind of solar battery crap and rely on cathing a signal from an American automic clock in Colorado - good luck with that while your in Thailand on vacation.
