The Ordinary Niacinamide 10% + Zinc 1% 30ml

A universal serum featuring a high 10% concentration of Niacinamide (Vitamin B3), a powerhouse ingredient that targets multiple skin concerns. This formulation’s action is synergistically supported by a 1% concentration of Zinc PCA (Zinc Pyrrolidone Carboxylic Acid) to deliver balanced, visible results. It is an essential treatment step for clarifying skin, refining texture, and boosting radiance.
The Science: Why It Works
The effectiveness of this formulation lies in the distinct and complementary actions of its key ingredients:

Niacinamide (10%): A multi-faceted B vitamin that is a fundamental component of healthy skin. In this high concentration, it works to:

• Reduce Congestion: Helps to clear impurities from pores, reducing the appearance of blemishes.Improve
• Barrier Function: Reinforces the skin’s natural barrier, improving hydration and resilience.
• Refine Skin Texture: Visibly smooths and softens the skin’s surface.
• Brighten Skin Tone: Independent studies confirm its efficacy in reducing dullness and promoting a brighter, more even complexion.

Zinc PCA (1%): This compound is the zinc salt of Pyrrolidone Carboxylic Acid. It complements the action of Niacinamide by:

• Balancing Sebum Activity: Helps to regulate and reduce the visible signs of excess oil production, leading to less shine and a more balanced complexion.

Key Benefits & Proven Results

• Refines Pore Appearance & Skin Texture: Dramatically minimizes the look of enlarged pores and smooths textural irregularities for a softer, more uniform surface.
• Controls Excess Sebum & Visible Shine: Actively balances oil production to reduce surface shine, leaving the skin looking fresh and matte without over-drying.
• Reduces Signs of Congestion: Works to decongest clogged pores, diminishing the appearance of skin blemishes and preventing new ones from forming.
• Enhances Skin Radiance: By addressing dullness and improving texture, this serum restores a healthy, luminous glow to the skin.

Clinical Data Shows: A significant improvement in skin smoothness and hydration within 7 days of consistent use, with a measurable reduction in excess oil within 3 days. (Based on a clinical study of 35 subjects applying the product twice daily for 8 weeks.)

Safety Note: Always perform a patch test prior to first use. If irritation occurs, cease use and consult a physician. Use only as directed on unbroken skin.

Regimen Building & Layering Guide

Proper layering is crucial for maximum efficacy and to avoid potential conflicts.

The Golden Rule: Avoid Direct Conflict with Vitamin C
This formulation should not be used in the same routine as products containing direct or ethylated forms of Vitamin C.

• Conflicting Ingredients: L-Ascorbic Acid (LAA), Ethylated L-Ascorbic Acid (ELAA).
• Why? Niacinamide can affect the integrity and reduce the effectiveness of these pure-form Vitamin C molecules.
• Solution: Use them at alternate times. A recommended approach is applying Niacinamide 10% + Zinc 1% in the AM and your Vitamin C product in the PM.

Sample Morning (AM) Routine for Oily/Blemish-Prone Skin:

1. Cleanse: Squalane Cleanser
2. Treat: Niacinamide 10% + Zinc 1%
3. Hydrate: Natural Moisturizing Factors + HA
4. Protect: Mineral UV Filters SPF 30 with Antioxidants

Sample Evening (PM) Routine with Vitamin C:

1. Cleanse: Squalane Cleanser
2. Treat (Hydration): Hyaluronic Acid 2% + B5
3. Treat (Antioxidant): Ascorbyl Tetraisopalmitate Solution 20% in Vitamin F
4. Seal: 100% Plant-Derived Squalane

Note: While this serum reduces the look of blemishes, it is not a treatment for acne. For persistent acne conditions, DECIEM recommends consulting a healthcare professional for treatments like Benzoyl Peroxide or Retinoic Acid.
