Circadia Vitamin A Gel​ 1 fl. oz.

✨ A 1% retinol face serum from CIRCADIA formulated for mature and UV-damaged skin — where consistent overnight cell turnover is the goal and visible texture refinement is the measure.

Retinol at this concentration is the functional core: nightly use progressively smoothes rough, sun-damaged surfaces, softens the look of fine lines, and fades residual post-acne discoloration. The clean, short-ingredient gel base keeps compatibility high, making it a natural retail follow-up after professional resurfacing services once skin has fully recovered. For clients new to retinoids, a graduated frequency — three nights per week building over time — supports tolerance without disrupting results.

Because retinol amplifies UV sensitivity, morning SPF becomes non-negotiable for every client on this protocol. That's an easy education moment and a straightforward retail pairing.

A strong retail fit for estheticians whose clients are targeting uneven texture, sun damage, or post-acne marks — and are ready for a results-oriented nightly active.

• Visibly smoother skin texture: Regular overnight use of Retinol at 1% helps skin appear progressively smoother and more refined, reducing the rough, uneven texture associated with sun-damaged and aging skin.
• Reduced appearance of fine lines and signs of aging: Retinol is among the most studied vitamin A forms for visibly improving the look of fine lines, wrinkles, and other surface signs of skin aging with consistent use.
• Improved appearance of UV-damaged skin: Helps visibly reduce the look of uneven tone, dullness, and textural irregularities associated with cumulative UV exposure over time.
• Minimized appearance of post-acne scarring and discoloration: Supports a more even-looking skin surface by helping reduce the visible appearance of acne scarring and residual pigmentation with continued nightly use.

1. Cleanse the client's face thoroughly and pat dry before application.
2. Dispense one drop of the gel onto a fingertip.
3. Apply directly to affected areas on the face and neck using gentle, even strokes.
4. Avoid the immediate eye area and any open or broken skin.
5. Allow the product to absorb fully; do not rinse.
6. Instruct the client to begin use on three evenings per week and gradually increase to five evenings per week as skin tolerance builds.
7. Use in the evening only; follow with broad-spectrum SPF the following morning.

Retinol introduction and service integration

For clients new to retinoids or with sensitive skin, a start-low-go-slow frequency is critical — three nights per week for the first two to four weeks before building. Retinol at 1% is a relatively high concentration for a leave-on retail product; advise clients that transient dryness, tightness, or mild flaking during the first weeks of use is a normal adjustment response, not an allergic reaction. This product is well-suited as a retail recommendation following professional resurfacing services (chemical peels, microneedling) — but should not be introduced until the skin has fully recovered, typically seven to fourteen days post-procedure. The simple, fragrance-free, short-ingredient formulation makes it a clean pairing with other leave-on actives that are not also retinoids.
