Retinal 3 serum

5 stars out of a maximum of 5

I absolutely love this retinal it’s amazing for your skin, reduces fine lines and once you apply it to your face it feels so soothing. I have noticed the fine lines under my eyes have gone. This product is so soothing in general for your skin and the consistency is so nice. I love this product and I would recommend it.

Perfect for retinol newbies

5 stars out of a maximum of 5

Now in my late 20s I decided to introduce retinol into my routine. I was cautious as I have quite sensitive skin, so this product allowed me start with a low strength. I already use the Medik8 Hydr8 Intense serum for a daily dose of hyaluronic acid, which is my favourite, so when I saw this formula was also infused with hyaluronic acid, glycerin and vitamin E, I couldn't wait to try it! My skin already looks smoother and more refined, so I will definitely repurchase!

Review: Beginners GEM - Medik8 Retinol 3TR Cream

5 stars out of a maximum of 5

I've been using the Medik8 Retinol 3TR Cream for a few weeks now, and it has become a staple in my skincare routine. As someone new to retinol, I wanted a product that was beginner-friendly, and this cream has been perfect. The cream's formulation is lightweight and absorbs quickly, making it easy to incorporate into my nighttime routine. I appreciate that it doesn't leave any greasy residue, which is a big plus for my combination skin. What impressed me the most is the time-release technology in Medik8 Retinol 3TR Cream. This feature ensures a gradual release of retinol throughout the night, significantly reducing the risk of irritation. I experienced minimal dryness and no flakiness, which can be common when starting retinol.
