I can totally help with the retinol concentration in this product! Well... to a certain degree at least. I've done some hw during this lifelong quarantine, so please bear with me. The Inkey List website lists "1% RetiSTAR stabilised Retinol", and "0.5% Granactive Retinoid" as their key ingredients. First, 1% RetiSTAR is not the same as 1% Retinol. RetiSTAR is made up of retinol, tocopherol (vitamin E), sodium ascorbate (vitamin C), and castor oil (in caprylic triglycerides). In effect, the amount of pure retinol concentration in this treatment serum is equal to 0.05% (*). That's 20x weaker than 1% pure retinol. Second, the 0.5% Granactive Retinoid is 1/10 of Hydroxypinacolone Retinoate (HPR). What is HPR? HPR is a retinoic acid ester. It is similar to retinoic acid (a.k.a. tretinoin or Retin-A, the active form of vitamin A), as it binds directly to the retinoid receptors of our skin cells (but with little to no skin irritation). So, what is Granactive Retinoid? Granactive Retinoid, an active technology from Grant Industries, is a complex of solubilized HPR (an active) in a 1:10 ratio with dimethyl isosorbide (a solvent). Therefore, when you see a Granactive Retinoid percentage, simply divide it by 10. To sum up, The Inkey List Retinol is basically 0.05% pure retinol and 0.05% HPR. Note: Most of the limited research on HPR is from its manufacturer, and there isn't a way of knowing what % of retinoic acid HPR is equivalent to atm. Feel free to DYOR!

I have never used the Inkey List retinol before and I'd love to try it !! :) Thank you so much for your review, your videos are always interesting and informative ! Can't wait to see your next video !xx

Fragrance and cruelty free makes this amazing! Just started using it last week and it’s fantastic!!! Totally works! My skin is clearer and I hope my fine lines fade over time. I have very acne prone sensitive combination skin. Wish the tube was bigger but I like the simple, black and white packaging. I use it every night; one night, on its own and one night after my moisturizing serum and moisturizing cream. Thank you for this great review! Your channel is fantastic!! And your give away is quite generous. New Subscriber here. Thank you so much! Be blessed.

Wow! What a fantastic review! And seriously....the best giveaway I've heard of! I'm obsessed with The Inkey List and I always praise their products. I have yet to try their retinol but I have always wanted to. I'm currently using Differin Gel so I'm not sure how to add a retinol into my routine. I believe I can go in alternating evenings though and would love to start doing that. The price point for this retinol is so great and you're so right when you said this is how companies should be doing their products in 2020; no fragrance, cruelty free and no dyes! Yes, please! Another fantastic video and thank you for yet another incredible giveaway. I can't wait to see your channel grow and grow just as I watched Hyram's grow so rapidly. Yours is bound for the same because the content is such top notch quality. Cheers!

_Okay your upload schedule is insane !_ Just stumble on your channel a few hours ago and saw that your channel is only about 3 to 4 months old and has already so many videos and great content about skin care. Your work ethic is unmatched and I like your videos a lot. *Keep going, I subscribed*

I’m so excited to try this product!! Thanks for the review 💜

Just got this, happy to see what happens to my sensitive acne prone ANNOYING skin :D i really liked its texture!

This is the video I watched that made me buy this product. I finally got my items delivered so tonight is my 1st night doing my skin care route. Cleansed with the oat balm cleaner, added the hyaluronic acid, retinol & then topped it with Sunday Riley’s Ice ceramics moisturizer. 🤞🏼

So I just purchased this yesterday from Sephora online, because I just recently managed to clear cystic acne I've been struggling with for years and I'm now trying to fade my PIH and even out the texture of my scars. Watching this made me sooo excited to receive it in the mail and try it. Thank you ❤️

Thanks for this very helpful video. I have The Inky List Retinol on order but I've never used a retinoid before and was confused how to get started. Love the straightforward instructions and the positive review. There are so many products out there and so many different formulations of retinoids that it's very hard to know if I chose the right one!

Wow 2 videos in one day we are lucky and I can’t wait for your full inkey list review video xx

I love love love your enthusiasm- it’s what really got me to finally get on with my skincare! I keep checking my order tracking to see how close I am to getting the inkey list retinol and Q10 antioxidant serum- trying my best to be patient lol This will be my first time trying the inkey list, so excited!!

(Loving the daily uploads btw)

Okay...I HAVE to try this! It sounds so amazing!

Ive never tried a retinol but after this review i will definitly be trying the inkey list !

I bough this as my first Retinol (along with a bunch of other Inkey List products to start my first proper skincare routine at 33 yo, lol), started using it last week, had no reaction after first application so I figured will try to just use it every other evening. 3 times done now and all is good! Btw, love your videos! Not a boring way to learn about skincare ❤️

Iv never used the inky list but would love to try them especially as they are getting such glowing reviews 🤞🏻 x

I started using this product about a month ago now after seeing a dermatologist rave about it. I was extremely worried about purging (I'm 27 and have suffered from acne since my teens) but I actually only had one or two minor spots and they disappeared very quickly. I felt a mild burning when I first used it but that went away after the third or fourth time applying (I started off every three days, now use it every other day). I'm in love! I got the eye cream as well and both together are giving me the best skin I've ever had. My skin is just very clear and glowy in a way which is hard to describe

A massive thank you for this video Rob! I'm 21 and I thought I want to wait till my mid 20s till I start Retinol but because I'm also acne prone I'm thinking maybe I should start earlier. I was looking for a good Retinol I can get in Germany and I just searched for this one on KZfaq and when I saw that you made a video I had to watch immediatly 😁🥰

Would have been nice to say what results you found. Any who, I'm sold 😂 i really like your chatty, straight to the point vids xx

I have just stared using this a few weeks ago after using a sample of the PC 1% and getting some sensitivity to it. I should have started slowly 🤣 I have been using this 3 times a week and had no negative reactions! I love it 🥰 Also, would love to be entered into the giveaway 😁

Just found your channel! Great review!!

I’m also a fan of The Inkey List’s Retinol. Though I just started using it. Guess what I’ve done... I got it on Tuesday. Today is Saturday... I’ve used it every single night 😶 Now I am.. a little bit dry. All I’ve dared to do to my skin today is wash last nights skincare (and retinol) off and cleans with the tiniest pearl sized amount of an Holika Holika cleanser and put some of The Inkey List’s Niacinamide .

I’m not really new to skin care, i’ve loved it since I was 13 I grew up with bad acne but now my skin is mosly clear!!🥰 tho.. my mom is new to skincare and she let me create a skincare routine for her which I’m very excited about, she has some eye bags and wrinkles under her eyes that I Think that I Can help with.. or hopefully I can, lol But it was a very good video, that help me understand a little bit more about retinol, ty and a very good giveaway🤍

Omg now I'm even more excited to try this, I ordered it and I'm actually kinda scared of retinol but now I'm more excited! Thank you for this review! Love u

I bought this today after the recommendation you gave me on your livestream last night! It the last one on the shelf too, fate or what?! Excited to get started with it!

First go at retinols ever. Thomas Roth spf 45 moisturizer is my go to right now with everything. I’ll see how it goes with it. My skin is sensitive and oily a lot. So hopefully it works ! Using a bit every 2-3rd night.

I was hesitant to try it because I haven’t seen many reviews but I may do now!

I'm planning to buy the ordinary granactive retinoid but it's always out of stock in my country. Your review helped me a lot. Will def. try this inkey list retinol instead 💕

Stumble upon your video and I love your accent

i just got this in the mail today. i've never used a retinol before but i'm hoping it will help my acne-prone skin. i'm 30, and i know a lot of my acne is hormonal, but fingers crossed this goes well. someone told me to only use it weekly, over my mostiurizer at first to ease into it, so i'm excited to see how it goes! also, nice to be introducted to your videos! just subbed

I would love to try this product! this giveaway is so generous

I found this super interesting! I’ve heard so much about retinol but have been super nervous to try it lolll

Great review. Starting this tonight.

gonna try this was using paulas choice 1% but its out of my budget tbh so this has a great price on it x

Thank you for the info, I’ve been wondering where to start with retinol

Totally agree with you.. Inkey’s Retinol serum and Oat Cleansing Balm are : 100 / 100 ... super star 🌟 products My opinion: The Inkey List beats The Ordinary in efficacy and ease-of-use and definitely in Results as well !

Hello, thank you so much for reviewing this product! .. i just got this product and i wanna make sure that i can use it with (kiehl’s midnight recovery concentrate serum)?? If you know ?

Another amazing video 😍😍

Sounds great. Would you say this is safe for near the eye area?

Neutrogena is anti-aging retinol is amazing and they guarantee it it’s been tested by dermatologist patients before they released it. After weeks my skin looked fantastic!

Ur channel clarity was super.. and also the way you are explained about the product is really great..

I've got the oatmeal cleanser and vitamin C serum in my Sephora basket as we speak. Excited to try them.

Hi!! I am new in your channel and I really love it, Thanks flor this review, i was looking for a new retinol serum and seems this is an amazing one:) congratulations for your channel! Kisses from 🇦🇩 Andorra :)

Thank you. I will try this.

Only a few days ago I was recommended this product for hyperpigmentation after getting bad acne last year, after seeing this review, I'm definitely going to give it a go. Thanks for a great review. Take care.

26th like Great content... Thanks for sharing

Great videoo i will definitely try out this brand 😍

Need to try a retinol, will deffo give this a try. Xx

Thanks for your review! It’s the only one I’ve found thats straight to the point and not too confusing! Can I moisture after using this or is it not really needed?

I have not tried this one, I’m curretly using The inkey list Bakuchiol (btw, it’ s great), but you video totally sold me Retinol. The inkey list should sponsore you :)

Good review. Thanks man

Im still not completely used to the 0.5%pure retinol from the ordinary so this product might be great to use between breaks from the other retinol :P

I just bought this, even more exciting now

The Inkey List collagen serum booster and polyglutamic acid is amazing. It actually works. I personally won't recommend using Retinol in summer but rather in winter days.

Have you tried the Versed Press Restart Gentle Retinol Serum? I don't know if you can get it the UK. Thanks!!

Yes!! I would definitely like to try and do a skincare video about it on my channel. And what should I do to enter ur giveaway

I love your videos 🌟

Only after 1 month use woow.. i like inkeylist formulations.

I recently purchased this retinol. I am taking it verrrrry slow. Love your energy 🙂

You are the reason I'm buying this product 😁😁😁

I am so excited to try this! I have ordered it and now waiting for it! But I have a question, is it okay if I use retinol in the evening, and salicylic acid in the morning??

I’ve been looking at some inkey products and wanting to give them a go, I’m trying out new skincare items for a month then reviewing them on my channel so I might have to put this on my list for my next review!! x x

🔥🔥🔥🔥 Use it in the evening The ordinary Retinol leaves yellow stains on sheets

Thank you 🖤🖤🖤

I'm buying it tommorrow

Wooow! This product sounds to be really great! And it's also very affordable. In my night time routine, I've been using a very expensive, yet very effective on my skin product: "The Estee Lauder night repair serum" (which I wouldn't want to quit using tbh). But I'd like to start slowly introducing a retinol as well. Do you think it'd be fine to combine the Inkey List Retinol + the Estee Lauder serum and layer a moisturizer at the end?

What a great review! I've heard a lot of great things about the inkey list brand! Would love to be entered in the giveaway!🤗

I would love to try it I tried many retinol but it didn’t works well for me.this one it sounds to be good with affordable prize so it seems to be win win situation if it works

I’m using this already but I want in on the giveaway lol xx

Could I use the inkey list retinol serum under eyes as well??

Wow it's very good👍

The ordinary has some gems. I might have to try this.

Great review! Let’s stay connected

Pick me! Pick me! LOL. Great video Rob. Can’t wait to see the whole Inkey List review video

Awesome to see retinol do good for your skin. Retinol definitely burned me. I’m trying to get it back now. I wanna try their products bad, especially the oat cleanser and the tranexamic acid! I’m not gonna beg, but I definitely need this! Thanks for the give away opportunity!

I know this video is a bit old but... I just bought this and tried it. Can't wait to see the results and if I like it

Im using inkey list retinol how many minutes should I wait before I apply moisturizer ?

Beautiful review... I was searching for an effective retinol as I want to incorporate retinol into my skincare... I am 41and have sensitive skin... Is it effective in fine lines and skin texture? Can I use it along with ordinary buffet in the same routine?

I bought this in the second week I got closed comedones on my forehead is it purging? Bcs i used to have closed comedones

Do I need to taper this initially? Like 2x a week for 2 weeks then every other day?

Hey, do you think I could use this after a facial oil like rose hip or before ?

Hello again! I have a question about using AHAs with retinol. I’ve been using the Inkey list retinol for about three weeks, every four days, and I’ve found it makes my skin way more sensitive to the tingling when I’ve tried to use my AHA overnight treatment (a few days after retinol). It’s so painful I have to wash it off immediately. Is there anything you can recommend so I can get the benefits of exfoliation or should I just wait fir my skin to adjust? Thank you!

Can u use retinol with salicylic acid? I heard that u can’t use them together but is it ok to use a low concentration of salicylic acid & retinol together in a routine

Is it effective for acne or not? 😊

Do you suggest it for someone with sensitive skin and post acne erythema? I wanna start using retinols but im afraid

Hieee....i've rosacea and very sensitive skin...can I use this retinol frm the inkey list and does it helps in reducing undereye wrinkles ...?

Hello. I am 25+ and I have not used retinol before. I am planning to use one. I have normal to dry skin. And I want to have a natural glow and prevent eye, mouth wrinkles. So, would u recommend me inkey list retinol or Cerave resurface retinol? Plz help.

Does the Inkey list retinol serum has fragrance or is it a fragrance free product?

Is buffering needed in the first couple weeks, this is what I’m doing and I’m not sure if it’s necessary or not(plus I’m new to Retinoids)

Is it for beginners? Can I use it as my first retinol serum?

Would you recommend this over The Ordinary retinol? :) s

🖤❤

I’m using the same one but for my undereye’s wrinkle Plz tell me if it is for wrinkles and dark circles or no Plz plz plz

Will it help with skin texture

I looked for the Inky list, do they have their own site? I don't want to support Sephora ever again!

Is it a good retinol for a beginner?

I have been absolutely loving The HA from the Inkey List! And this retinol also sounds fab! I wasnt a fan of the texture of the ordinarys retinols personally. I’m super excited for tomorrow’s video!! And would love to be entered in your super generous giveaway 💙💙💙 Stay safe xx

Do you moisturize after applying this?

hi hun, how do u use this?
