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.

Always use a sunscreen during the day in conjuncture with this product.

Not to be used if pregnant or breastfeeding.

Great for aggressive chewers
Color: Grey
Tuff toy, my yorkie has been trying to tare squeaker out for about 3 days, he works on the fur part but so far it stands up to his chewing, I have gone thru 3 other toys this week so glad thi one works! It lasted 8 days. They need to make whole toy out of material and put fur on top of the tuff material. Once he found out wetting the fur softens it he pulled the seam apart.

Does not stand up to aggressive chewers
Color: Grey
Supposed to be for heavy chewers. My dog destroyed this toy literally in less than 15 minutes. Tore the tail which I sewed back together and then she tore off the nose and pulled out stuffing. Don't know how they tested this. She is only 6 months old and it didn't stand up to her play. Do not recommend if you have an aggressive chewer.

Won't last a day
Color: Blue, Color: Blue
My 50 lb. Pitt bull destroyed this chew toy in 15 minutes. One week later. I'm changing my rating from a one to a five. My girl spent up until now ripping it apart and pulling the stuffing and squeaker out. She had so much fun that I bought her another one. When I took it out of the box for her, she was so happy, she immediately tried to tear it apart.

Lasted 2 minutes
Color: Grey, Color: Grey
Gave it a 2 star bc it was cute and on time. I have a GSD- a mildly aggressive chewer. This toy literally lasted 2 minutes and there was stuffing coming out so I had to take it away. Wish I would have read the reviews before I purchased.

Only Made It Two Weeks
Color: Grey, Color: Grey
This toy easily became my Fig's favorite toy. The squeaker wasn't as annoying as it is in many other dog plushies. However, that's where the positives end. After the first week, there was a hole in the stitching on its neck. I sewed it up, but it obviously did not last. The squeaker went silent after a few more days. I bought it on March 28th, and it is now April 12th. It's just a rag, now. RIP little honey badger. You did well in your short life time.
