Review: Best Retinal I’ve ever used! It works for me! - This has to be the best retinal product I have used. (And I have tried most of them, murad, ordinary, the list goes on.) Ive been using this for about 6 months now. I started off by using the retinal 3 progressed to 6 and I’ll go on to retinal 10 next. It’s creamy in texture, smells pleasant and is absorbed into the skin almost immediately. My skin is on the sensitive side and this retinal has never caused me any problems even though it’s a lot stronger than ‘retinol.’ My skin feels and looks smoother and hydrated, my deeper lines have been drastically improved, and although you can’t expect the results of a face lift it’s made a big difference to how I feel and look. It’s especially helped with the finer lines around my lips. One tube does actually go along way (mine lasts months) and I apply it every evening before bed without fail. I only use one pump full on one side of my face and one pump full on the other before using a smaller amount on my neck. Dark spots have been reduced and my skin texture looks more even. When you get to the end of the tube and nothing more comes out cut the tube in half as there’s still stuff in there! I always look out for this when desertcart are doing special deals or offers and usually can get it when it’s at its best price.
Review: Is this the best retinol out there...? - I can't speak highly enough of Medik8's retinol range - it's kind enough for my sensitive skin, the cream formula minimises the risk of it degrading, and the different strengths mean you can adjust daily based on what your skin is doing. I've been using 6 & 10 for some time now, and dared to venture to 20. It's noticeably thicker than 10, and also makes your face shockingly yellow (this is a sign of good quality retinol, apparently), a little sticky on the pillow. But despite its strength, I've had no irritation, using once or twice a week, alternating with 10. I always us a peptide first (Medik8 or Vichy89), and if I notice any dry or tight patches, I revert to 6 for a few days. I've used retinol for so long I wouldn't have a skin 'transformation', but Im in no doubt that retinol has been keeping my skin texture in good nik, and this is by far one of the best I've used.

### ⭐⭐⭐⭐ Buckle up buttercups, v long and brutally honest review
*by N***Y on 28 October 2022*

I used medik8 for over a year building from 3 to 6 to 10, with 10 over most of it and eventually daily. Pros: -gentle as long as you build up in strength n frequency and don’t combine with actives like acids on same night. -Smells nice -Nice creamy consistency -Spreads and absorbs well. Cons- pump container isn’t always great, and can waste some when nearly empty- cut tube open to use the last lil bit. -expensive but if you shop around online you can often find it cut price somewhere. Check amazon, look fantastic, beauty bay etc. It does make a difference but *over time*, its important to keep expectations realistic and I’m going to drum this right in now. Retinaldehyde or any retinoid for that matter will not stop ageing nor give you Botox results and especially not after just one month nor 2 nor 3. Sorry, but its retinoid not a liquid facelift. But out of all the retinoids I have used, inc the ordinary, this one made the most difference. And as much as Itd be great if it did, using retinoid cream alone without other care taken alongside it (eg keeping it clean, protected, moisturised) will limit results.try to target the cause as well as treat the problem. WEAR SUNSCREEN!! retinoids will do nothing if you arent protecting from sun damage so of course it will seem like its not working, because the sun is undoing what good it does. SPF, everyday rain or shine. Get into the habit of using it or youre wasting your time and money. What it did for me: it did not do much to my deep forehead lines but I had crows feet forming where I squint a lot and they are virtually gone now. It helped alongside practicing relaxing my face muscles more, wearing SPF and wearing sunglasses on sunny days. Some enlarged pores have gone, only the v worst ones remain. Made my skin softer and reduced some pigmentation from past sun damage. I had a brownish spot under my eye from it which is now barely visible. But again, you NEED to protect it from future sun. It helped my acne problem. It was bad deep cystic acne. I got into skincare when struggling with it, some spots would crop up in the same place. I tried AHAs/BHAs & they helped abit but only short term and on surfaced spots. This is where the retinoids, and eventually medik8, came in. My skin was in a pretty bad way at first after a lifetime of neglect and went through a long 6 month purging process, so be prepared for many many spots- it feels like it will never end at times but this is normal with retinoids, its cell turnover+++ pushing years of crap out. I finally came out of it and now have clear skin, after persevering. There can be side effects like dryness but I have oily combo skin so didnt really get that. However its normal to get the odd side effect from retinoids so expect them. My routine: wash, retinoid, moisturise. SPF in daytime, repeat. Clean pillowcases. Only touch face with clean hands. Protect in the day, clear treat and restore at night, is what I go by. I no longer use this product because I have moved on from retinaldehyde to tretinoin (stronger stuff) so no longer need the medik8. But medik8 crystal retinal is a good retinaldehyde product to use when moving on from retinol, or as a bridge retinoid to build up to prescription strength. (Retinyl parmitate to retinol to retinaldehyde to tretinoin+) Ultimately, you should get results if you: - use it as part of a consistent skin routine - practice good skin hygiene - Use sunscreen everyday - persevere through purging and initial side effects - keep up with using it regularly There is a wealth of info on the tinterweb and by dermatologist/aestheticians on retinoids, care while using them, what to expect etc. its well worth learning.
