If you're looking to speak confidently about your favorite brightening tools, this one’s for you. Instead of just saying “this line brightens,” let’s break down why—and how each ingredient supports brighter, healthier skin.
Dermo Bright C Ampoule
Key actives: Niacinamide, Ascorbyl Glucoside, Resmelin
This clever blend tackles hyperpigmentation at the source.
Niacinamide also known as Vitamin B3, is a water-soluble vitamin widely recognized for its versatile skin benefits. In terms of brightening and pigmentation control, niacinamide works by inhibiting the transfer of melanosomes—pigment-containing organelles—from melanocytes (the pigment-producing cells) to keratinocytes (the skin’s surface cells). This means it doesn’t stop melanin production itself but prevents pigment from reaching the skin’s surface, leading to a more even skin tone and reduced dark spots over time.
Ascorbyl Glucoside is a stable, water-soluble derivative of Vitamin C, created by combining ascorbic acid with glucose. This modification enhances its stability and allows for gradual release of active Vitamin C once applied to the skin, making it less irritating than pure Vitamin C (ascorbic acid) while still delivering powerful brightening benefits. Ascorbyl Glucoside works by inhibiting tyrosinase activity—the enzyme responsible for melanin production—thereby reducing the formation of dark spots and promoting a more even complexion. Additionally, it offers antioxidant protection against free radicals, supports collagen synthesis, and helps improve skin texture and firmness.
Resmelin is a natural brightening ingredient extracted from the leaves of the Artemisia capillaris plant, known for its powerful skin-calming and pigment-regulating properties. It works by gently inhibiting tyrosinase, the enzyme responsible for melanin production, helping to reduce the appearance of dark spots and uneven skin tone without causing irritation.
It’s rounded out by soothing botanicals—mallow, peppermint, primula and more—to calm and support the skin’s ecosystem .
Whitening Shield Sheet Mask
Key Actives: Niacinamide, Adenosine, Pollustop® + botanicals
This protective mask isn’t just about hydration—it’s a barrier against pollution.
Niacinamide, as explained above, is a water-soluble vitamin with versatile skin benefits, helping to brighten by inhibiting the transfer of pigment-containing melanosomes from melanocytes to skin surface cells.
Adenosine is a naturally occurring molecule found in all human cells, playing a vital role in cellular energy transfer and signaling. In skincare, adenosine is prized for its ability to smooth wrinkles, improve skin elasticity, and promote collagen production, making it a powerful anti-aging ingredient. It is typically produced through biotechnological fermentation processes to ensure purity and efficacy. Beyond its wrinkle-reducing benefits, adenosine also has anti-inflammatory properties that help calm and soothe the skin, supporting overall skin health.
Pollustop® is a clinically backed, biotechnology-derived ingredient designed to protect the skin from modern environmental stressors. Made from a high-molecular-weight polysaccharide, it forms a breathable, non-occlusive barrier on the skin—like a lightweight second skin—that blocks fine dust (PM2.5), heavy metals, UV rays, and chemical pollutants. Studies have shown that Pollustop® can reduce pollutant penetration by up to 46% after just 12 hours and block up to 95% of heavy metal particles from adhering to the skin. Beyond surface protection, it defends against oxidative stress, inflammation, and cellular damage at a deeper level, helping maintain the skin’s mitochondrial health and integrity. This mask can be a game changer to support clients exposed to urban environments, high UV exposure, or post-procedure sensitivity. Skin remains protected, calm, and resilient—without feeling suffocated.
In addition, antioxidants like rosemary, licorice, and green tea support barrier health, while 5 types of hyaluronic acid revive moisture. It’s brightening plus silver-lining backup
Brightening Cream
Arbutin, Acerola extract + peptides
Arbutin is a naturally derived compound extracted primarily from plants like bearberry, cranberry, and wheat. It brightens skin by directly inhibiting tyrosinase, the enzyme responsible for melanin production. Unlike ingredients that only block pigment transfer, arbutin works earlier in the pathway to reduce melanin synthesis itself, helping to fade dark spots and promote an even complexion over time.
Acerola is a natural fruit extract derived from the acerola cherry, renowned for its exceptionally high Vitamin C content. This powerful antioxidant brightens the skin by neutralizing free radicals and supporting collagen synthesis, which helps improve skin tone and texture. Unlike synthetic Vitamin C, acerola offers gentle yet effective brightening benefits while nourishing and protecting the skin.
Copper Tripeptide-1 is known for its wound-healing and anti-inflammatory properties. It promotes collagen and elastin production, helping to improve skin firmness and repair damage.
Palmitoyl Pentapeptide-4 (often called Matrixyl) stimulates collagen synthesis and supports skin regeneration, reducing fine lines and wrinkles by enhancing the skin’s natural repair process.
Spot Lumedic
Niacinamide, Licorice root, Ceramide NP
Formulated for pinpoint correction, this serum addresses stubborn spots.
Licorice root contains a powerful active compound called glabridin, which inhibits tyrosinase—the enzyme responsible for melanin production—making it an effective brightening agent. Glabridin also has anti-inflammatory and antioxidant properties that help soothe irritated skin and reduce redness, making licorice root ideal for sensitive or inflamed skin prone to hyperpigmentation. Additionally, licorice root extracts can help calm redness and support skin barrier health.
Ceramide NP is a type of ceramide—lipid molecules naturally found in the skin’s outermost layer—that plays a crucial role in maintaining the skin’s protective barrier. It helps lock in moisture, prevent water loss, and protect against environmental irritants and pathogens. When skin lacks ceramides, it becomes dry, sensitive, and prone to damage. By replenishing Ceramide NP, skincare products help restore barrier function, improve hydration, and promote overall skin resilience.
Ascorbyl Tetraisopalmitate (lipid-soluble C), Betaine, Tocopheryl Acetate, Allantoin
Ascorbyl Tetraisopalmitate (lipid-soluble C) is a lipid-soluble derivative of Vitamin C that combines four molecules of palmitic acid (a fatty acid) with one molecule of ascorbic acid. This unique structure allows it to penetrate the skin’s lipid-rich layers more effectively than traditional water-soluble Vitamin C forms. It delivers powerful antioxidant benefits, promotes collagen synthesis, and inhibits melanin production by blocking tyrosinase activity, leading to brighter, more even-toned skin. Its lipid solubility also makes it more stable and less irritating, suitable for sensitive skin types.
Betaine is a natural amino acid derivative typically extracted from sugar beets. It functions as a highly effective humectant and osmolyte, helping the skin maintain hydration by balancing water levels within skin cells. Betaine protects skin cells from dehydration caused by environmental stress and harsh skincare ingredients, making skin feel soft, smooth, and resilient. Additionally, it has soothing properties that reduce irritation and inflammation, making it ideal for sensitive or dry skin.
Tocopheryl Acetate is a stable, esterified form of Vitamin E commonly used in skincare for its antioxidant and moisturizing benefits. Once applied, the skin converts it into active Vitamin E (tocopherol), which helps protect cells from free radical damage caused by environmental stressors like UV radiation and pollution. This antioxidant action supports skin repair, reduces signs of aging, and strengthens the skin’s barrier. Additionally, Tocopheryl Acetate has moisturizing properties that keep skin hydrated and supple.
Allantoin is a naturally occurring compound known for its soothing, healing, and moisturizing properties. It helps calm irritated skin, promotes cell regeneration, and supports the repair of damaged tissue, making it a popular ingredient in skincare for sensitive, dry, or compromised skin. Allantoin also acts as a gentle exfoliant by softening keratin, helping to smooth rough skin and improve texture.
Ion‑To Ampoule
Niacinamide, Ceramide NP, Dipotassium Glycyrrhizate + Glycyrrhiza Glabra Root Extract, Ubiquinone
Dipotassium glycyrrhizate is a salt derived from glycyrrhizic acid, the active compound in licorice root. While it doesn’t directly lighten pigmentation, it has strong anti-inflammatory and soothing properties that help calm irritated skin and reduce redness. By minimizing inflammation, it supports a healthier skin environment and prevents pigmentation from worsening, making it an important supportive ingredient in brightening formulations.
Glycyrrhiza Glabra Root Extract comes directly from the root of the licorice plant, rich in glabridin—a compound that inhibits tyrosinase, the enzyme responsible for melanin production. By blocking tyrosinase, licorice root extract reduces melanin synthesis, helping fade dark spots and even skin tone.
Ubiquinone is a naturally occurring antioxidant also known as Coenzyme Q10, found in every cell of the body. It helps protect skin cells from oxidative stress caused by UV exposure and pollution, which can trigger pigmentation and premature aging. While not a direct brightener, ubiquinone supports skin energy production and repair mechanisms, helping maintain healthy, radiant skin over time.
