Skin Diligent CEL Retinal Serum is a high-performance night serum that works on several visible signs of aging at once: it smooths the look of wrinkles, refines skin texture, revives radiance and supports firmness. Its retinal is encapsulated and released gradually, for high tolerance even on sensitive skin and on skin that has never used retinoids. The fragrance-free formula pairs it with the brand's CEL Complex.

Key Benefits

  • Smoother-looking skin: softens the look of lines and wrinkles over the weeks.
  • Firmer feel: works on collagen in three ways to support skin firmness.
  • Refined, radiant skin: refines skin texture and revives a dull complexion.
  • Gentle retinal: gradual release designed for good tolerance, even on sensitive skin.
  • Thoughtful formula: vegan, fragrance-free, made in France, and tested on the finished formula for the absence of estrogenic and androgenic endocrine disruption.

Key Ingredients

Retinal, or retinaldehyde, is one step closer to the active form of vitamin A than retinol, as it needs a single conversion step in the skin. Here it is encapsulated in Protium heptaphyllum resin, which releases it gradually. The CEL Complex, patent pending, combines botanical extracts, peptides and exosomes to help reduce cellular stress in the skin.

Skin Diligent advises against using CEL Retinal Serum during pregnancy. Ask your doctor or pharmacist for advice.

How to Use

Use Skin Diligent CEL Retinal Serum in the evening. Shake well, then apply 3 to 4 drops to clean, slightly damp skin and wait one minute before your night cream, such as the brand's Exosome Advanced Night Cream. On sensitive skin, or if you have never used retinoids, apply it every other night for two weeks, then every night as your skin tolerates it. Use a day cream with SPF protection in the morning.

Frequently Asked Questions

How do I use Skin Diligent CEL Retinal Serum?

In the evening, on clean, slightly damp skin. Skin Diligent recommends shaking the bottle, applying 3 to 4 drops and waiting one minute before the night cream. Start every other night for two weeks if your skin is sensitive or new to retinoids, then use it nightly as tolerated.

What is the difference between retinal and retinol in Skin Diligent CEL Retinal Serum?

Retinal is one step closer to the active form of vitamin A. Retinal, or retinaldehyde, needs a single conversion step in the skin, while retinol needs two. Skin Diligent encapsulates the retinal in this serum so that it is released gradually and stays stable.

Does Skin Diligent CEL Retinal Serum cause peeling or redness?

It is designed to keep this to a minimum. Peeling, tightness and redness in the first weeks are the main reasons people give up retinoids. Here, the retinal is encapsulated in a plant resin that releases it gradually, and the serum was tested on women with sensitive skin. A reaction is still possible, so start slowly.

Can I use Skin Diligent CEL Retinal Serum in summer?

Yes, as long as you apply it in the evening and use a sunscreen in the morning. Skin Diligent explains that retinoids speed up the renewal of surface skin cells, and new skin is more vulnerable to UV. During intense sun exposure, space out the applications.

Is Skin Diligent CEL Retinal Serum suitable for all skin types?

Yes, according to Skin Diligent. Its encapsulation technology and the CEL Complex are designed for good tolerance on every skin type, including sensitive and blemish-prone skin. If your skin is very reactive or prone to visible redness, ask your dermatologist for advice before you start.
