Retinol

What is retinol?

Retinol is a derivative of Vitamin A and one of the most clinically studied renewal actives in skincare. As a Skin Identical molecule, it is converted by the skin into retinoic acid — the form that supports cellular turnover. Retinol features within The Rejuvenating Collection alongside Retinal, Bakuchiol, and DNA Repair Enzymes to support overnight skin renewal.

What does retinol do for skin?

Retinol supports the skin's natural turnover process, helping refine the appearance of fine lines, uneven texture, and pigmentation, while improving the look of skin firmness and clarity. With consistent use, retinol works to reveal a smoother, more refined, and visibly rejuvenated complexion. Results emerge progressively over weeks and months of nightly application.

Which RATIONALE formulations contain retinol?

Retinol features within The Rejuvenating Collection, alongside Retinal, Bakuchiol, and DNA Repair Enzymes. The hero formulation from RATIONALE is #6 The Rejuvenating Night Crème. Vitamin A is present in other formulations, in lower concentrations as part of multi-vitamin complexes, including #2 The Brightening Serum, #2 The Brightening Hydragel, and #4 The Nourishing Crème.

How do I introduce retinol into my Ritual?

Begin gradually. Apply #6 The Rejuvenating Night Crème two to three evenings per week, increasing to nightly use as tolerance builds. Layer over Nourishing formulations to maintain comfort. Always pair with daily SPF, as retinol increases skin sensitivity to solar and environmental damage. For tailored introduction, consult our Client Services Team or a RATIONALE Skin Therapist.

Is retinol safe during pregnancy or breastfeeding?

We always recommend speaking to a medical professional before incorporating a topical retinol formulation into your routine during pregnancy or breastfeeding. Bakuchiol – a plant-derived active that mimics the renewal action of Vitamin A – is widely considered a safe alternative during this time of increase sensitivity. RATIONALE offers the Bakuchiol-based #6 The Rejuvenating GelCrème formulation to support renewal during this period. Always consult your healthcare practitioner before adjusting your skincare.

Can I use retinol with Vitamin C or Hydroxy Acids?

Yes. Vitamin C is best applied as part of a morning skincare routine for antioxidant defence, while retinol works overnight for cellular renewal, making them a complementary pairing. Retinol can also be layered with Hydroxy Acids in the evening, though we recommend introducing one active at a time and pairing with Nourishing formulations to maintain barrier comfort.

What is the difference between retinol, Retinal, and Bakuchiol?

Retinal (retinaldehyde) is the most direct precursor to retinoic acid and works most rapidly. Retinol converts more gradually and is well tolerated by most skin types. Bakuchiol is a plant-derived active that mimics the renewing effects of Vitamin A and is suitable for sensitive skin or during pregnancy.
