WHAT IS THE DIFFERENCE BETWEEN STARTER RETINOL SERUM VS ADVANCED RETINAL? 

Starter Retinol is formulated with gentle retinoids, perfect for beginners, whereas Advanced Retinal contains a potent level of Retinal (0.2%) so is best for those who are confident with Retinoid use. 

WHICH IS STRONGER: RETINOL OR RETINAL? 

Retinal. It needs less conversion in the skin to get to the active stage (Retinoic Acid)

WHAT IS THE DIFFERENCE BETWEEN RETINOL & RETINAL?

Retinol and Retinal are both types of Retinoid.

Retinol is a gentler form of Vitamin A, making it well suited to beginners and those with sensitive skin. Once applied, retinol needs to convert twice in the skin — first into retinal and then into retinoic acid, the active form the skin can use. Because of this two-step conversion process, results appear more gradually, typically within 8–12 weeks. While effective, retinol is less potent than retinal and carries a minimal risk of irritation, which makes it a reliable and approachable entry point into vitamin A skincare.

Retinal, on the other hand, is a more potent derivative of Vitamin A and sits just one step away from retinoic acid. It only needs to convert once in the skin, allowing it to work more efficiently and deliver faster visible results, often within 4–8 weeks. Due to its higher potency, retinal can work up to 11 times faster than retinol and is best suited to experienced retinol users. While the irritation risk is moderate, this is typically balanced with barrier-supporting ingredients to help maintain skin comfort.

WHEN SHOULD I APPLY RETINAL SERUM?  

In the PM after cleansing and before moisturizing.  

HOW OFTEN SHOULD I USE IT?  

We’d recommend starting 2 to 3 times a week, if you feel like you can build up to more frequently then the product can be used every evening. 

CAN I USE IT EVERY NIGHT?  

Yes with consistent use and gradual build up. 

CAN I USE IT LONG TERM?  

Yes, you can continue to use this product ongoing. 

WHY NOT IN THE MORNING?  

Retinoids can leave skin sensitive to the sun, so they should not be used in the AM. Also, always use SPF in your AM routine! 

IS IT SAFE TO USE WHEN I'M GOING OUT IN THE SUN?  

It is safe if you're using it in the evening and applying SPF well before going out in the AM.

WHAT SHOULD I AVOID LAYERING WITH?  

Other retinoids or exfoliating acids 

HOW DO I USE IT ALONGSIDE VITAMIN C?  

While you can use Retinol and Vitamin C together, it's better to use vitamin C in the day time for antioxidant protection and Retinol in the evening. Vitamin C and Retinoids can occasionally cause sensitivity if paired together. 

WHEN WILL I SEE RESULTS?  

You should start to see results within one week, however by four weeks you should start to see a real difference, for maximum results use for 3 months. 

WHAT IF IM EXPERIENCING IRRITATION?

IS PURGING NORMAL?  

There is a potential for purging, however any purging should be short lived. Purging can happen when using Retinoids and Exfoliating Acids. Learn more about purging here 

WHAT DOES ENCAPSULATED MEAN?

Our retinoid encapsulated systems use protective carriers to protect them within the formula, support even absorption, and allow them to release gradually on skin. This supports product stability and delivers consistent results with a gentler feel and less risk of irritation.

WHEN SHOULD I START USING ADVANCED RETINAL?  

We advise from 35 upwards. 

DOES THIS REPLACE THE INKEY 1% RETINOL?  

We have discontinued the SuperSolutions 1% Retinol Serum, this product is a good alternative as it's also suitable for those who are experienced with Retinoids. This Advanced Retinal product contains 0.2% Retinal as opposed to 1% Retinol. 

WHAT IS THE PERCENTAGE OF RETINAL?  

0.2% Retinal 

WHAT IS THE DIFFERENCE VS BEGINNER RETINOL?  

Starter Retinol is formulated with gentle retinoids, perfect for beginners, whereas Advanced Retinal contains a potent level of Retinal (0.2%) so is best for those who are confident with Retinoid use. 

WHICH IS STRONGER: RETINOL OR RETINAL?  

Retinal is a more potent retinoid. It needs less conversion steps in the skin to get to the active stage. 

IS IT SUITABLE FOR SENSITIVE SKIN?  

This product hasn't been tested on sensitive skin.

CAN IT HELP WITH HYPERPGIMENTATION?  

This product will help reduce the appearance of hyperpigmentation, with consistent use.  

WHY IS IT YELLOW?  

Retinoids are yellow because of how their molecules interact with light. This is completely normal and expected for Retinoids. 

WILL IT MAKE MY SKIN YELLOW?  

The strong yellow nature of Retinal may cause a temporary yellow tint on some skin tones, but if this does happen it will be temporary and short lived. 

WILL THE COLOUR TRANSFER ON MY BEDDING, PILLOWS & PYJAMAS?  

There is a potential for transfer due to the yellow nature of Retinal, so we advise letting the product sink in fully before allowing contact with textiles. We also advise applying a moisturiser after use. 

WHY HAS MY RETINOL CHANGED COLOUR?  

Retinoids can oxidise over time, any minor changes to colour will not impact on the performance of the product. 

IS IT VEGAN?  

Yes

We advise that you do not use any retinol/ retinal/ vitamin A products without consulting your doctor first when pregnant. 

IS IT SAFE TO USE WHILST BREASTFEEDING?
