✨ CIRCADIA L-Ascorbic Acid Powder is a pure, anhydrous vitamin C treatment for estheticians targeting hyperpigmentation, UV-related dullness, and early skin laxity — mixed fresh at the chair for full-strength delivery every time.

Pre-formulated vitamin C products degrade in the bottle long before they reach your client's skin. This powder format sidesteps that entirely: L-Ascorbic Acid stays stable and unoxidized until the moment you mix it, meaning the active hits at peak potency across the entire contact window. The result is a measurably brighter, more even appearance clients can see after a single session. Paired with CIRCADIA's Alpha Gel Base, it dissolves uniformly and applies cleanly — no guesswork, no wasted product.

🧪 The two-ingredient INCI list — Ascorbic Acid and Maltodextrin — keeps the formula clean and the story simple, which also makes it a natural segue into a retail SPF conversation post-treatment.

A strong fit for practices building out brightening and antioxidant services for UV-damaged or uneven-tone clients.

• Antioxidant Defense Against Environmental Damage: L-Ascorbic Acid neutralizes free radicals generated by UV exposure and environmental pollutants, reducing the visible impact of oxidative stress on the skin's appearance.
• Visible Brightening of Uneven Skin Tone: Helps reduce the appearance of hyperpigmentation, dark spots, and dullness associated with UV damage and environmental exposure, leaving skin looking more luminous and even.
• Firmer, More Refined Skin Appearance: Supports a visibly tighter, more toned skin appearance, particularly beneficial for clients experiencing early signs of laxity or loss of definition.
• Maximum Potency at Point of Service: The anhydrous powder format keeps L-Ascorbic Acid stable and unoxidized until mixed at the time of treatment, ensuring the client receives the active at full strength — a distinct advantage over pre-formulated aqueous vitamin C products that degrade over time.

Ascorbic Acid - known as L-Ascorbic Acid (Vitamin C): The purest, most bioavailable form of vitamin C used in professional skincare. As a potent antioxidant, it neutralizes free radicals generated by UV exposure and environmental pollutants, visibly brightening the appearance of uneven skin tone and dullness. At effective concentrations (typically 10–20%), it also supports a firmer, more refined skin appearance. In this two-part system, the anhydrous powder format preserves full potency until the moment of activation at mix, delivering peak activity across the 10–15 minute leave-on contact window.

Maltodextrin: A polysaccharide excipient used as a carrier and flow-aid in powder cosmetic formulations. In this anhydrous system, maltodextrin encapsulates and stabilizes the L-Ascorbic Acid in dry form, protecting the active from premature oxidation during storage. It also aids uniform dissolution when the powder is blended into the Alpha Gel Base at the time of service, ensuring even distribution of the vitamin C across the applied mask.

1. Cleanse and prepare the client's face according to standard pre-treatment protocol.
2. Dispense 2 teaspoons of CIRCADIA Alpha Gel Base into a clean portion cup.
3. Using the provided scoop, add 2 scoops of L-Ascorbic Acid Powder to the Alpha Gel Base.
4. Mix thoroughly until the powder is fully dissolved and the mixture is uniform.
5. Apply the freshly prepared mixture to the client's face using a fan brush, avoiding the eye area.
6. Leave the mask on for 10–15 minutes.
7. Remove with a warm, damp towel.
8. Pat the skin dry and proceed with post-treatment protocol as appropriate for the service.

Maximizing vitamin C activity at the point of service

Because L-Ascorbic Acid oxidizes rapidly on contact with air and moisture, the mixture should be prepared immediately before application and used without delay — do not pre-mix batches. Discard any unused portion after the service; re-use of prepared product compromises active integrity and client results.

This treatment pairs well with a post-service SPF recommendation, reinforcing the UV-protection narrative you can use as a retail moment: explain to the client that the vitamin C just applied works against past UV damage, while a daily SPF prevents new damage — a natural segue to home-care product recommendations.
