🧪 A multitasking corrective serum from Herbal Skin Solutions built for estheticians who need one backbar workhorse to address brightening, acne control, and hydration across a wide client mix — without juggling multiple treatment products.

The formula pairs Mandelic Acid and Niacinamide to target hyperpigmentation and visible blemishes: the AHA exfoliates gently enough for sensitive skin (its larger molecular size slows penetration vs. glycolic), while Niacinamide works on tone, sebum regulation, and barrier support simultaneously. A four-form Hyaluronic Acid complex layers surface occlusion with deeper stratum corneum hydration, keeping post-treatment skin comfortable rather than tight. Potassium Azeloyl Diglycinate — a gentler azelaic acid derivative — rounds out the redness and acne-control strategy, making the serum compatible with reactive skin types that can't tolerate harsher actives.

This slots cleanly into corrective facials, post-peel finishes, and dermaplaning protocols as a leave-on treatment layer, and doubles as a retail recommendation for clients managing breakouts or uneven tone at home.

A strong fit for practices running acne, brightening, or hydration services on a broad, mixed-concern clientele.

• Visible brightening and more even skin tone: Mandelic Acid gently exfoliates the skin's outer surface to support cell turnover, helping fade the appearance of post-blemish marks and uneven pigmentation over time. Niacinamide complements this by helping reduce visible discoloration, resulting in a clearer, more radiant-looking complexion.
• Deep and sustained surface hydration: A multi-weight hyaluronic acid complex — including crosspolymer, hydrolyzed, acetylated, and standard sodium hyaluronate forms — delivers moisture at different levels of the skin surface. The crosspolymer and high-molecular-weight forms reduce transepidermal water loss at the surface, while smaller-weight forms penetrate more deeply into the stratum corneum for longer-lasting moisture retention and a plumper, more supple skin appearance.
• Reduced appearance of blemishes and excess shine: The combination of Mandelic Acid, Oligopeptide-10, and Potassium Azeloyl Diglycinate works at the skin surface to help reduce the appearance of active blemishes, visibly control T-zone excess shine, and support a clearer-looking complexion over continued use.
• Calmed appearance of redness and uneven tone: Potassium Azeloyl Diglycinate — a gentle azelaic acid derivative — helps reduce the visible appearance of redness and surface discoloration, supporting a more uniform complexion. Its mild profile makes it compatible with sensitive and reactive skin types.
• Antioxidant protection at the skin surface: Boswellia Serrata Resin Extract contributes antioxidant activity at the skin surface, helping protect the complexion's appearance against oxidative stress from daily environmental exposure.
• Reinforced skin surface barrier feel: Emollient esters (Triheptanoin, Coco-Caprylate/Caprate) combined with a dense humectant matrix help smooth and reinforce the skin surface's moisture barrier feel, reducing the sensitized or tight sensation that can follow exfoliating treatments.

Mandelic Acid - known as Mandelic Acid (AHA): An alpha-hydroxy acid derived from bitter almonds with a larger molecular size than glycolic acid, which slows its skin penetration and makes it well tolerated even on sensitive skin. At functional concentrations, it exfoliates the outer layers of the stratum corneum, supporting cell turnover, helping to fade the appearance of post-inflammatory hyperpigmentation, and improving overall skin clarity and texture.

Niacinamide - known as Niacinamide (Vitamin B3): A water-soluble form of vitamin B3 positioned at INCI rank 3, indicating a meaningful working concentration. Niacinamide is a multi-functional active recognized for supporting visible pore minimization, reducing the appearance of uneven skin tone and hyperpigmentation, helping regulate sebum production in the T-zone, and reinforcing the skin's surface barrier.

Sodium Hyaluronate Crosspolymer, Hydrolyzed Sodium Hyaluronate, Sodium Acetylated Hyaluronate, Sodium Hyaluronate - known as Hyaluronic Acid Complex (Multi-Weight HA): Four distinct forms of hyaluronic acid appearing at positions 22, 26, 30, and 33 in the INCI list, delivering hydration at different depths of the skin surface. The crosspolymer and high-molecular-weight forms act at the outer skin surface to reduce transepidermal water loss; the hydrolyzed and acetylated forms carry smaller molecular footprints that facilitate deeper penetration into the stratum corneum for more sustained moisture retention. Collectively they support a plumper, more supple skin appearance.

Potassium Azeloyl Diglycinate - known as Potassium Azeloyl Diglycinate: A stabilized, water-soluble derivative of azelaic acid combined with glycine. It helps even the appearance of skin tone, reduces visible redness, and supports sebum regulation on the skin surface, making it especially relevant for acne-prone and redness-prone skin types. Its milder profile versus free azelaic acid makes it suitable for sensitive skin.

Boswellia Serrata Resin Extract - known as Boswellia (Frankincense) Extract: A plant resin extract positioned in the lower-mid portion of the INCI list, included in the product's antioxidant complex. It provides surface-level antioxidant activity that helps protect the skin's appearance from oxidative stress associated with environmental exposure, supporting the serum's antioxidant protection claim.

Oligopeptide-10: A short-chain synthetic peptide with recognized antimicrobial and skin-calming surface activity. It contributes to the serum's acne-control positioning by helping reduce the visible appearance of blemishes and supporting a clearer skin surface, complementing the AHA and azeloyl diglycinate in the formula's acne-correction strategy.

1. Ensure the client's face is thoroughly cleansed and dried before application.
2. Dispense 2 pumps of the serum onto clean fingertips or directly onto the client's face.
3. Gently press and smooth the serum across the face, avoiding the immediate eye contour area.
4. Allow the serum to absorb fully into the skin before applying any subsequent products such as moisturizer or SPF.
5. Incorporate into both AM and PM corrective treatment protocols as appropriate for the client's skin concern and service plan.

Service integration and client-type guidance

When used as a backbar serum in facial services, this product fits naturally after the treatment/mask step and before the moisturizer/SPF finish — the leave-on format maximizes active contact time within the service window. For clients with active breakouts or significant hyperpigmentation, consistent use across both AM and PM routines accelerates visible results; this is a strong retail conversation point when recommending the take-home SKU.

For sensitized or first-time AHA clients, consider applying only 1 pump and monitoring the skin's response before progressing to a full 2-pump application. Mandelic Acid's larger molecular size makes it a gentler AHA entry point than glycolic, but individual tolerance still varies. Avoid layering with other AHA or exfoliating actives in the same service session to prevent cumulative sensitization.
