RETINAL VS RETINOL: WHAT’S THE DIFFERENCE?

Retinal is one step closer to its active form than retinol, allowing it to act more directly on signs of ageing. Our CEL™ Retinal Serum combines 0.15% encapsulated retinal for gradual release with the patent-pending CEL™ Complex, for effective age-defying action, even on sensitive skin.

01

FOR SKIN THAT HAS NEVER TOLERATED RETINOL.

Its encapsulated retinal is gradually released to smooth fine lines and wrinkles while improving skin tolerance, even for sensitive skin.

02

PROVEN TO HELP SKIN STAY YOUNGER FOR LONGER.

The CEL™ Complex acts at the cellular level on mechanisms linked to ageing, helping skin stay firmer, smoother and more resilient over time.

03

MADE FOR SENSITIVE SKIN.

Tested on 20 women aged 35 to 60, all with sensitive skin, over 56 days.

HOW TO USE IT IN YOUR NIGHT ROUTINE

The CEL™ Retinal Serum is step 2 of the Skin Diligent night routine.

01 · Cleanse. Massage a small amount of Triple Action Cleanser onto damp skin for 20 seconds, then rinse.

02 · Treat. Shake the bottle, then apply 3 to 5 drops of CEL™ Retinal Serum to slightly damp skin. Wait 1 minute.

03 · Nourish. Finish with Exosome Advanced Night Cream, massaging gently.

Getting started: new to retinoids? Use the serum every other night for the first 3 weeks, then every night as tolerated. Always wear sunscreen in the morning.

WHAT’S INSIDE THE CEL™ RETINAL SERUM

CEL™ COMPLEX

Cellular Epigenetic Longevity: a proprietary bioactive complex of botanical biotech extracts, peptides and exosomes. Extends cellular health, slows skin ageing and delays senescence. Helps preserve skin vitality, resilience and a more youthful appearance over time.

ENCAPSULATED RETINAL

Retinal is 11× more effective than retinol. Ours is encapsulated to allow for gradual release and improved stability, helping to support good skin tolerance, even for sensitive skin. This encapsulation also helps protect the molecule from oxidation and optimise its bioavailability, for enhanced efficacy with minimal sensitivity.

ADDRESSES ONE OF THE MAIN REASONS PEOPLE STOP USING RETINAL

Independently tested on 20 women with sensitive skin. Excellent tolerance.

WE TEST WHAT ALMOST NO ONE TESTS.

Chemicals can behave differently together than alone. It is called the cocktail effect. So we test the finished formula, not single ingredients.

Tested free of estrogenic and androgenic endocrine disruptions.

CEL™ RETINAL SERUM FAQ

What is the difference between retinol and retinal?

Retinal is a more advanced derivative of vitamin A in the conversion chain: it requires only one enzymatic transformation to become active (compared to two for retinol), making it more powerful and effective than retinol, while reducing the risk of irritation.

Does the CEL™ Retinal Serum cause irritation or “retinol burn”?

No. The CEL™ Retinal Serum does not cause “retinol burn” - the burning sensations, redness or peeling often associated with traditional retinoids.

Thanks to its slow-release encapsulated retinal and CEL™ Complex (Cellular Epigenetic Longevity Complex), it works deep within the skin without causing irritation. Its tolerance has been tested on sensitive skin, making it perfectly suitable for those who have previously reacted to conventional retinols.

We recommend the application of a light night cream like Skin Diligent Exosome Advanced Night Cream to help with the moisturisation at night. Avoid thick rich creams.

Why encapsulate the retinal in a botanical resin ?

Encapsulation in natural Protium heptaphyllum resin acts as a plant shield that:

  • protects the molecule from oxidation and instability
  • allows for gradual release into the skin
  • reduces the risk of irritation, even on sensitive skin.
Is it suitable for all skin types ?

Yes. Thanks to its encapsulation technology and combination with CEL™ Complex, the serum is designed to offer optimal tolerance, even on sensitive and acne-prone skin.

Can I use during pregnancy and breastfeeding?

No, as with all retinoids, retinal (and its derivatives) is not recommended during pregnancy and breastfeeding. Although CEL Retinal has been tested free of estrogenic and androgenic endocrine disruptions, the accumulation of vitamin A, such as retinoids, has a risk of teratogenicity.

I am in my teens, can I use this serum?

This product is formulated for those who start showing signs of ageing. For teens, we would only recommend as a course of treatment for acne-prone skin.

Pleasant to use.

Hard to say as I have only been using this product for one week. I can say it’s nice to apply as long as your skin is damp and is not greasy at all. Will it improve my skin? Time will tell.

espoir de bons résultats

J'adore tous vos produits. Ils ont vraiment amélioré la qualité et le confort de ma peau mature (j'ai 75 ans).

Comme j'ai la peau extrêmement sensible, j'utilise le rétinal avec précaution (1 à 2 fois par semaine). Pour l'instant, aucune irritation, mais ma peau est un peu sèche le lendemain.
Je reste très optimiste.

Prometteur

Je viens juste d'utiliser ce sérum et n'ai donc pas assez de retour sur son efficacité. Je peux néanmoins confirmer qu'il n'agresse pas la peau, qu'il est facile à utiliser, qu'il n'est pas gras sur la peau. Sérum prometteur pour le peu d'utilisations à ce jour.

Tolérance optimale

Très bonne expérience. L'application du sérum est agréable et confortable pour la peau. Excellente tolérance. Impression d'une peau un peu plus ferme depuis 1mois et demi d'utilisation. Seul bémol : le sérum disparait un peu trop vite (faible quantité pour un usage au quotidien)

Bonjour,
Nous recommandons d'appliquer 3 à 5 gouttes pour le visage et le coup (a appliquer sur un visage tres légèrement humecte pour faciliter sa diffusion). Sur cette base d'utlisation et en l'appliquant tous les soirs, le serum va durer 3 mois.

Efficacité au rdv !

Ma peau sensible le tolère et les résultats sont là. Ma peau est lumineuse, mon mari m’a demandé si j’étais maquillée ce we . non pq? Tu as bonne mine ma chérie . J’utilise toute la gamme de la marque et je vais bientôt acheter les pré/ pro biotiques pour voir si cela va agir sur les symptômes de la ménopause. En toute confiance.

Belle innovation

Le gel est très agréable et la peau est très repulpée au réveil. Un super produit, utilisable également le matin contrairement à la majorité des produits au rétinol 👌

Un must have

Excellent produit qui, combiné à la crème de nuit, garantit une peau lumineuse et rebondie au réveil.
Tous les avantages du rétinol dans une formule douce sans les inconvénients majeurs du rétinol (rougeur, irritation).
Je recommande chaudement comme tous les produits Skin Diligent que j'ai à présent adopté au quotidien.

A truly effective product

After three weeks of use, my skin is brighter, my complexion more even and, above all, my skin texture is finer and my pores are tighter.
This is the first time I've experienced all these benefits combined.
I was hesitant because my skin is quite sensitive, but I didn't experience any burning or tingling sensations.
Well done, Skin Diligent 😍

J'aime beaucoup

J'avais toujours craint d'utiliser un retinol par peur que ce soit un peu irritant. J'ai malgré tout tenté ma chance en lisant votre descriptif et je suis bluffé par ses effets. Je ne l'utilise encore qu'un soir sur 2 apres 4 semaines mais je compte passer a 2 jours sur 3 tres vite, voire tous les soirs.

Celine (France)
Produit vraiment performant

3 semaines d’utilisation et ma peau est plus lumineuse, mon teint plus uniforme et surtout mon grain de peau plus fin, les pores plus serrés.
Une première pour tous ces avantages combinés.
J’étais hésitante car ma peau est assez sensible mais aucune sensation de chauffe, picotements…
Bravo Skin Diligent 😍
