Frequently Asked Questions
What is retinaldehyde, and how does it differ from retinol?
Retinaldehyde is a powerful derivative of vitamin A, known for its fast-acting age-defying benefits. Unlike retinol, retinaldehyde requires just one conversion step to become active in the skin, making it work 11x times faster than standard retinol* to target fine lines, wrinkles, and uneven texture.
How do I incorporate retinaldehyde products into my skincare routine?
We recommend starting with lower concentrations of retinaldehyde if you’re new to the ingredient, such as 0.01% or 0.03%, to allow your skin to adjust. Gradually, you can work your way up to stronger formulas like 0.2% or 0.24%, applying them in the evening after cleansing and before moisturising. Learn more about retinal in our guide.
Can I use retinaldehyde products if I have sensitive skin?
Yes, retinaldehyde is our favourite form of vitamin A as it is gentle enough for sensitive skin and less irritating than traditional retinol. Medik8's retinal serums are specially formulated to minimise irritation while providing visible youth-renewing benefits.
How often should I use retinaldehyde serum?
Start by using retinaldehyde serum 2-3 times a week if you’re just beginning your vitamin A journey, then gradually increase to nightly use as your skin builds tolerance. Always follow with a moisturiser and use sunscreen during the day as part of your skincare routine. If you're already using vitamin A and switching to Medik8, you can use your serum every night, provided you choose a similar strength.
What are the benefits of using retinaldehyde in my skincare routine?
Retinaldehyde is known for its ability to accelerate cell turnover, boost collagen production, and visibly reduce the appearance of fine lines and wrinkles and dark spots. It works faster than retinol, delivering smoother, youthful-looking skin with fewer signs of irritation.
Can I use retinaldehyde products with other skincare ingredients like vitamin C or niacinamide?
Yes, retinaldehyde pairs well with other ingredients like vitamin C and niacinamide. For best results, use vitamin C in the morning alongside sunscreen and retinaldehyde in your nighttime routine, the foundation of our CSA philosophy.
What is the difference between Medik8's 0.1% and 0.2% retinaldehyde products?
Medik8 offers a unique ladder of strengths in our retinaldehyde products, including both 0.1% and 0.2% retinal serums to cater to different skin tolerances and needs.
