KEY ACTIVE INGREDIENTS
Niacinamide (Vitamin B3) – 10%
The star ingredient of this formulation. At 10% concentration, Niacinamide delivers clinically proven results in sebum regulation, pore refinement, and acne reduction. It works by inhibiting 5-alpha-reductase, the enzyme responsible for triggering excess oil production. Additionally, it strengthens the skin barrier by increasing ceramide synthesis and possesses potent anti-inflammatory properties that calm active breakouts.
Zinc PCA (Zinc Pyrrolidone Carboxylic Acid) – 1%
A powerful complement to Niacinamide, Zinc PCA delivers multi-dimensional benefits for acne-prone skin:
- Antimicrobial Action: Zinc PCA exhibits direct bacteriostatic activity against Cutibacterium acnes (formerly Propionibacterium acnes), the primary bacteria responsible for inflammatory acne lesions. This provides a targeted approach to reducing active breakouts.
- Sebum Regulation Enhancement: While Niacinamide inhibits 5-alpha-reductase, Zinc PCA works through a complementary pathway to further suppress sebaceous gland activity. Together, they create a synergistic effect that reduces oil production more effectively than either ingredient alone.
- Anti-Inflammatory Support: Zinc PCA calms redness and soothes irritation, making it particularly beneficial for inflamed acne lesions and sensitive skin types.
- Delivery Enhancement: As a naturally occurring component of the skin’s NMF (Natural Moisturizing Factor), Zinc PCA facilitates deeper penetration of Niacinamide into the epidermis, maximizing its efficacy.
- Biofilm Disruption: Recent research indicates that Zinc PCA can help disrupt the biofilm formation of acne-causing bacteria, preventing colonization and reducing the likelihood of recurrent breakouts.
Dexpanthenol (Provitamin B5) – 0.5%
A powerful skin repair and soothing agent. Dexpanthenol penetrates deep into the epidermis, converting to Pantothenic acid which accelerates wound healing, reduces transepidermal water loss, and provides intense hydration. It significantly minimizes the risk of irritation often associated with high-concentration Niacinamide.
Allantoin – 0.2%
A gentle, non-irritating skin protectant with exceptional soothing properties. Allantoin promotes cell regeneration, reduces redness, and calms inflammation. It is particularly beneficial for sensitive and acne-prone skin, providing immediate relief from irritation and discomfort.
EFFECTS ON THE SKIN
Antimicrobial Protection (Zinc PCA)
Zinc PCA provides direct antimicrobial activity against C. acnes by interfering with bacterial cell membrane integrity and inhibiting bacterial proliferation. This action is particularly valuable for preventing new breakouts and reducing the severity of existing inflammatory lesions. When combined with Niacinamide’s sebum-normalizing effects, Zinc PCA creates an unfavorable environment for bacterial growth, addressing both the cause and the symptoms of acne.
Sebum Regulation
Niacinamide at 10% significantly reduces sebum production by inhibiting the action of 5-alpha-reductase—the enzyme responsible for converting testosterone into DHT, which triggers excess oil secretion. Clinical studies demonstrate up to a 50% reduction in sebum output with consistent use over 4 to 8 weeks.
Pore Refinement
By regulating keratinization and reducing sebum oxidation, Niacinamide minimizes the appearance of enlarged pores. The result is smoother, more refined skin texture with visibly tighter pores within 4 to 6 weeks of daily use.
Barrier Strengthening
Niacinamide increases ceramide synthesis in the stratum corneum, reinforcing the skin’s natural lipid barrier. This prevents transepidermal water loss (TEWL) and protects against environmental aggressors, pollutants, and irritants.
Anti-Inflammatory Action
Potent anti-inflammatory properties calm active breakouts, reduce redness, and suppress cytokine release. This makes the serum effective for inflammatory acne lesions, post-inflammatory erythema, and even rosacea-prone skin.
Antimicrobial Support
While not directly antibacterial, Niacinamide creates an unfavorable environment for C. acnes by normalizing sebum composition and pH. This indirectly reduces bacterial proliferation and prevents new breakouts from forming.
Hyperpigmentation Fading
By inhibiting melanosome transfer from melanocytes to keratinocytes, Niacinamide effectively reduces post-inflammatory hyperpigmentation (PIH), acne marks, and uneven skin tone, revealing a brighter, more luminous complexion.
BENEFITS

DIRECTIONS FOR USE
Morning and Evening Routine
Begin by cleansing your face with a gentle, pH-balanced cleanser. Pat the skin dry, or leave it slightly damp for better absorption. Pump one to two drops of the serum onto your fingertips and gently pat it over your entire face, avoiding the delicate eye area. Allow the serum to absorb fully for one to two minutes before following with a lightweight, non-comedogenic moisturizer. In the morning routine, always finish with a broad-spectrum sunscreen of SPF 30 or higher as your final step to protect the skin and maximize results.
Important Application Tips
For the first week, apply the serum once daily in the evening to allow your skin to adjust. After one week, you may increase frequency to twice daily—morning and evening—if the skin tolerates it well. A single pump is sufficient for the entire face; more is not better with active ingredients. Applying the serum to slightly damp skin can enhance absorption, though this is optional. Always perform a patch test on the inner forearm at least 24 hours before first use to ensure compatibility.
Recommended Pairings
For enhanced hydration, pair this serum with Hyaluronic Acid. If using Vitamin C, apply it in the morning and reserve Niacinamide for the evening to minimize potential sensitivity. For advanced anti-aging and acne treatment, Niacinamide combines exceptionally well with Retinol in the PM routine. When used alongside Salicylic Acid, the exfoliating and sebum-regulating effects are amplified, making this combination particularly effective for oily, acne-prone skin.

ADVANCED CLINICAL INSIGHT
The Science Behind Niacinamide 10%
Niacinamide, a form of Vitamin B3, exerts its effects through multiple pathways that collectively transform oily, acne-prone skin. At the sebaceous gland level, it inhibits 5-alpha-reductase Type 1 activity, reducing the conversion of testosterone to dihydrotestosterone by up to 40 percent. This directly decreases sebaceous gland activity and sebum output. Simultaneously, Niacinamide normalizes follicular keratinization, preventing the buildup of dead skin cells that clog pores and lead to comedones.
On the inflammatory front, Niacinamide suppresses the NF-κB pathway, which is responsible for producing pro-inflammatory cytokines such as IL-6, IL-8, and TNF-α. This anti-inflammatory action reduces the redness and swelling associated with active acne lesions. Furthermore, Niacinamide boosts NADPH production, enhancing cellular energy and repair mechanisms. By increasing ceramide and free fatty acid synthesis, it improves the stratum corneum lipid content by 30 to 40 percent, reinforcing the skin barrier against moisture loss and environmental damage.
Clinical Efficacy Data
In an 8-week clinical study comparing Niacinamide 10% to a placebo vehicle, participants experienced a 48 percent reduction in sebum output, a 36 percent reduction in inflammatory lesions, and a 42 percent improvement in pore size appearance. Another 12-week trial comparing Niacinamide 10% to Clindamycin 1% found comparable efficacy in reducing acne lesions, with the added benefits of better tolerability and the absence of antibiotic resistance concerns. When Niacinamide 10% was combined with Retinol 0.25% over a 16-week period, the results were even more impressive—a 68 percent improvement in overall skin texture and a 52 percent reduction in post-inflammatory hyperpigmentation.
The Synergy of Niacinamide and Zinc PCA
The combination of Niacinamide 10% and Zinc PCA 1% represents one of the most well-studied and clinically validated pairings in dermatology. While Niacinamide targets sebum production, inflammation, and hyperpigmentation, Zinc PCA provides complementary antimicrobial and biofilm-disrupting properties. This dual-action approach addresses the multifactorial nature of acne—excess sebum, bacterial colonization, inflammation, and abnormal keratinization—more effectively than either ingredient alone.
In comparative studies, the Niacinamide-Zinc PCA combination has demonstrated superior results in reducing both inflammatory and non-inflammatory lesions compared to Niacinamide alone, with a faster onset of action and improved tolerability. The combination also shows enhanced efficacy in preventing new breakouts, making it an ideal choice for long-term acne management.
Formulation Synergy
The effectiveness of this serum is enhanced by the careful selection of complementary ingredients. Dexpanthenol accelerates epidermal repair and reduces the potential for Niacinamide-induced irritation, while Allantoin provides immediate soothing relief, reducing redness within 15 to 30 minutes of application. Sodium PCA maintains hydration levels, preventing the drying effect that sometimes accompanies active treatments. EDTA chelates metal ions that could cause oxidation or discoloration, preserving the formula’s clarity and potency. PEG-12 Dimethicone improves spreadability and leaves a silky, non-oily finish that users appreciate in a daily serum.
pH and Stability Considerations
The target pH of 5.8 to 6.2 is critical for both Niacinamide stability and skin compatibility. At this pH range, hydrolysis is minimized, and the active ingredient remains fully potent. This pH also closely matches the skin’s natural pH of approximately 5.5, reducing the risk of irritation. Niacinamide has a tendency to raise pH over time, but the inclusion of EDTA and the buffer system in this formulation maintains long-term stability. The formulation has been tested for thermal stability and remains effective at temperatures between 25 and 40 degrees Celsius for over 12 months.
Comparative Analysis
When compared to competing serums, this formulation stands out for several reasons. While many products contain 10 percent Niacinamide, not all are pH-optimized, which can compromise efficacy. This serum is precisely balanced at 5.8 to 6.2, ensuring maximum performance. The inclusion of Dexpanthenol and Allantoin provides a soothing complex that is often absent in competitor products. The texture is distinctly non-sticky and lightweight, whereas many alternatives feel tacky or heavy. EDTA stabilization is another advantage, as many formulations lack this protective chelating agent.
Long-Term Safety Profile
During the first 1 to 4 weeks of use, sebum reduction begins and pores start refining. A mild adjustment phase may occur but typically resolves quickly. By weeks 4 to 8, significant reductions in breakouts and improvements in skin tone become visible. Maximum efficacy is achieved between weeks 8 and 12, with noticeable texture improvement and barrier strengthening. Beyond 6 months of continuous use, the results are sustained, and the product remains safe for long-term daily application without adverse effects.
Regulatory and Quality Standards
This serum is formulated in accordance with ISO 22716, the international standard for Good Manufacturing Practices in cosmetics. It has undergone dermatological testing and has been confirmed as non-comedogenic through testing on human sebaceous gland cultures. The formula is completely free from parabens, phthalates, artificial fragrances, and artificial colorants, ensuring a clean, safe, and effective product for all skin types.
