Both are part of the retinoid family and derivatives of vitamin A. Vitamin A helps to boost cell turnover but first it needs to be converted to retinoic acid, which happens naturally when applied to the skin. Retinal is further along the vitamin A pathway than retinol - it's just one 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. Want more info? You got it!

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, so 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 Vitamin A Serum.
