PM - After cleansing, apply 1 pump to hands and press lightly into face and neck avoiding the eye area. Wait a few minutes before applying other serums then finish with moisturiser. Always use broad-spectrum sunscreen the following morning. 

First-timers: Use twice a week at night for two weeks. Gradually build skin tolerance and use every alternate night for another two weeks, and then nightly, or as needed to suit skin tolerance.

Advanced users: Use nightly. 

Note: Retinal and ascorbic acid are powerful ingredients, and can cause irritation when used together at once. We recommend using Daybreak Vitamin C Serum in the morning and Super Retinal Vitamin A Serum at night if you’d like to use both.

Not recommended when pregnant or breastfeeding. Use with caution if also taking dietary supplements or using other products containing vitamin A. Immediately after use, avoid direct exposure to sunlight. Do not apply to damaged or inflamed skin.

FAQ's

Decoding the Power of Retinal and Retinol: Your Guide to Radiant Skin

Navigating the world of skincare ingredients can often feel like a puzzle, especially when it comes to understanding the nuances between retinal and retinol. While they share similarities in their names and their remarkable abilities to rejuvenate and enhance your skin, they're not quite the same.

At Kester Black, we believe in illuminating the science behind skincare. We've unravelled the complexities of these two potent ingredients to present you with a clear, concise understanding. This way, you're empowered to choose what truly resonates with your skin's unique needs. Dive into our guide and discover the path to your most radiant skin yet.

What is retinol?

Retinol, a vital member of the retinoid family and a derivative of vitamin A, is like a master key to unlocking youthful skin. It works wonders by stimulating skin cell renewal and boosting collagen production. This not only enhances your skin's radiance, tone, and texture but also ushers in a rejuvenated, youthful glow. 

The journey of vitamin A through the 'vitamin A pathway' is fascinating. Upon application, retinol transforms first into retinal and then into retinoic acid. It's in this final, active stage that the true power of retinol shines, bringing visible, transformative results to your skin.

What is retinal?

Meet Retinal, (short for retinaldehyde) a distinguished member of the retinoid family and a form of vitamin A. Its position in the vitamin A pathway is what sets it apart - it's just one transformative step away from becoming retinoic acid. This means retinal not only acts faster on your skin compared to retinol, but it also offers additional benefits.

Retinal takes the lead over retinol, offering a next-level skincare experience. This advanced form of vitamin A works up to 11 times faster than traditional retinol [1], delivering outstanding anti-aging, radiance-enhancing, and skin-smoothing benefits. With Retinal, you're not just hoping for change – you're expecting rapid, transformative results for your skin.

[1] G. Siegenthaler et al., Retinol and retinal metabolism, Biochemical Journal, 1990, 268, pp 371-378

Retinal serum is a skincare marvel, renowned for reducing fine lines and wrinkles, enhancing skin texture and tone, and may also be effective in assisting acne. It's an all-in-one solution for a youthful, radiant complexion.

Yes, 'Retinal' and 'Retinaldehyde' are interchangeable terms. Retinal is simply the shorter, more common name for Retinaldehyde.

For mature and ageing skin:

Retinal works wonders for those seeking a more youthful appearance. It's a rapid performer, delivering collagen-boosting effects faster than retinol, thus reducing visible signs of ageing in less time. Its efficiency makes it a favourite for mature skin.

For sensitive skin

Our unique formulation comes into play here. We've carefully blended Retinal with soothing ingredients like Canadian Willowherb and Chamomile Extract, specifically to reduce irritation.

For blemish-prone skin:

Retinal stands out with its antibacterial properties, setting it apart from retinol. It actively combats the bacteria responsible for breakouts and clogged pores, aiding in achieving a clearer, more radiant complexion.

Retinoids are powerful, but they may initially cause dryness or irritation for new users. That's why at Kester Black, we recommend a gradual introduction to our retinoid products. Begin with a lower frequency of application, then slowly increase as your skin becomes accustomed. This method helps to significantly reduce the likelihood of irritation, allowing your skin to adapt naturally over time.

Our formulations are meticulously crafted to be as gentle as possible, aiming to minimise any discomfort and ensure a positive experience with our products.

After cleansing, apply 1 pump to hands and press lightly into face and neck avoiding the eye area. Wait a few minutes before applying other serums then finish with moisturiser. Always use broad-spectrum sunscreen the following morning. 

First-timers: Use twice a week at night for two weeks. Gradually build skin tolerance and use every alternate night for another two weeks, and then nightly, or as needed to suit skin tolerance.

Advanced users: Use nightly. 

Note: Retinal and ascorbic acid are powerful ingredients, and can cause irritation when used together at once. We recommend using Daybreak Vitamin C Serum in the morning and Super Retinal Vitamin A Serum at night if you’d like to use both.

Not recommended when pregnant or breastfeeding. Use with caution if also taking dietary supplements or using other products containing vitamin A. Immediately after use, avoid direct exposure to sunlight. Do not apply to damaged or inflamed skin.

Absolutely, while retinal is potent, it's often considered less irritating than prescription retinoids. Our formulation is designed to be gentle, ensuring that even delicate skin can enjoy the rejuvenating benefits of retinal without irritation.

The path to visible results with retinal is a journey worth taking. Generally, you may start noticing improvements in your skin's texture and appearance within a few weeks. However, the most significant transformations, like reduced lines and enhanced radiance, typically unfold over several months. Patience is key – your skin is undergoing a beautiful transformation, revealing a more youthful, glowing complexion with each use of Kester Black's Super Retinal Serum.
