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.

Key Ingredients

Niacinamide

Known for its ability to help brighten the appearance of skin, support healthy ageing including the appearance of fine lines, wrinkles, elasticity and hyperpigmentation, and help support skin strength and barrier function.

Palmitoyl Tetrapeptide-7 and Palmitoyl Tripeptides

Peptides work to nourish collagen production, which helps reduce the appearance of fine lines and wrinkles and leave skin looking firmer and plumper.

Epilobium Angustifolium Extract

A powerful extract found in the Northern Canadian Prairies, it’s known for its natural soothing, calming, and antioxidant benefits, which can help support redness, soothe irritation and the appearance of acne.

Retinal

The most potent and effective derivative of Vitamin A that doesn’t require a prescription. 100% natural and renowned for its proven multiple skin benefits, it works to nourish skin elasticity and firmness, reduce the appearance of lines and wrinkles, smooth skin texture, target hyperpigmentation for healthy pigmentation management.

Aphanothece Sacrum Exopolysaccharides

Extracted from the Japanese blue-green algae that lives in the clear springs of Mount Aso and can only flourish in pristine conditions, its high molecular weight delivers superior hydration and can absorb 5x more water than sodium hyaluronate. It also has a unique ability to form a transparent film over skin to help support skin integrity and support a healthy response to pollutants, leaving skin soft and hydrated.

Glycerin

A natural humectant, it is an incredible moisturising and skin-replenishing ingredient as it helps attract moisture from the air and deliver it deep into the lower layers of the skin to the epidermis. It leaves skin moist, bouncy and dewy, and also helps maintain skin health when using active or drying products. Our Glycerin is Palm-Free.

Chamomilla Recutita (Chamomile) Flower Extract

Extracted from the Chamomile herb, it contains high levels of antioxidants and has anti-inflammatory benefits to help calm, soothe and moisturise skin. It can help reduce redness and blemishes, provide relief from inflammation, soothe sensitive skin, and help defend from free radicals that can contribute to ageing.

Salicylic Acid

A Beta Hydroxy Acid that gently exfoliates the surface of skin and helps regulate oil production, target congestion, reduce blackheads, control inflammation from acne and pimples, and support healthy pigmentation and healthy skin renewal. It also works to support the effectiveness of Vitamins A and C, as well as Alpha Hydroxy Acids.

Cocos Nucifera Fruit Juice

Fermented Coconut Juice is a postbiotic ingredient produced by the fermentation of lactic acid bacteria. It has antioxidant, antimicrobial and moisturising benefits to help maintain the balance of the skin’s microbiome to keep it healthy. It also stimulates Collagen 1 synthesis, which helps support healthy skin resilience, and stimulates Collagen 3, which helps promote skin health and the appearance of elasticity.

Propanediol

Derived from corn sugar, it functions as a solvent, humectant, emollient and a preservative booster. It helps improve the texture of products, and the absorption of ingredients to boost their effectiveness. It also has moisturising properties to leave skin feeling smooth and soft while reducing moisture loss.

Xanthophylls

A carotenoid pigment with a yellow colour that has antioxidant properties.

FAQs

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!

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, 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.
