Abib Glutathiosome Dark Spot Serum Vita Drop 50ml

Abib Glutathiosome Dark Spot Serum Vita Drop 50ml

Abib Glutathiosome Dark Spot Serum Vita Drop is an intensive multi-pathway brightening serum formulated to address dark spots, post-acne hyperpigmentation, sun-induced discolouration, and overall uneven skin tone — with clinically measurable improvement visible in as little as 3 days of use. The formula is built around four distinct brightening mechanisms operating simultaneously: liposomal Glutathione delivery, a triple-form Vitamin C system stabilised by the proven C+E+Ferulic Acid antioxidant complex, Niacinamide-driven melanin transfer inhibition, and Centella Asiatica triterpenoid UV-melanin suppression. These are supported by a comprehensive barrier-repair and hydration matrix to ensure that brightening benefits are delivered without compromising skin integrity or sensitivity. Water-based, lightweight gel texture. Alcohol-free. Fragrance-free. Essential oil-free. Hypoallergenic — dermatologist tested for skin irritation.

Glutathiosome™ Technology — Liposomal Glutathione Delivery

Glutathione is a tripeptide (Glutamic Acid + Cysteine + Glycine) that serves as the body’s master endogenous antioxidant — synthesised in every cell to neutralise reactive oxygen species and maintain redox homeostasis. In the context of skin brightening, Glutathione inhibits tyrosinase, the key rate-limiting enzyme in the melanin biosynthesis pathway, by switching melanin production from the darker eumelanin pathway toward the lighter phaeomelanin pathway — resulting in progressive brightening and depigmentation. It also directly scavenges the free radicals and UV-generated oxidative stress that trigger post-inflammatory hyperpigmentation (PIH), making it particularly effective for post-acne dark marks.

The challenge with topical Glutathione has historically been its poor skin absorption — its large molecular size and hydrophilic nature limit passive diffusion through the lipid-rich stratum corneum. Abib’s proprietary Glutathiosome™ technology addresses this with a liposomal micro-bead encapsulation system using Hydrogenated Lecithin (a phospholipid with high structural affinity for the skin’s own lipid bilayers) and cyclodextrin inclusion complexation (Hydroxypropyl Cyclodextrin), encapsulating Glutathione within micro-beads that break open upon skin contact. Clinical testing demonstrates that this delivery system increases absorption speed and depth by 152.82% and absorption rate by 52.64% versus unencapsulated Glutathione — allowing the active to reach the melanocytes in the basal layer of the epidermis where melanin is actually synthesised.

Triple Vitamin C System — Stabilised by C+E+Ferulic Acid Synergy

Three complementary forms of Vitamin C provide multi-layered, multi-depth brightening and antioxidant activity:

• Ascorbic Acid (Pure L-Vitamin C): The most potent and best-studied form of Vitamin C — directly inhibits tyrosinase activity, stimulates dermal collagen synthesis via prolyl hydroxylase activation (improving skin firmness and reducing the appearance of fine lines), and provides powerful antioxidant protection against UV-induced free radical oxidative damage. Its limitation is inherent instability — it oxidises rapidly in the presence of light, air, or alkaline pH. In this formula, stability is addressed by the C+E+Ferulic Acid complex described below
• 3-O-Ethyl Ascorbic Acid (EAC): A stable ether derivative of Vitamin C where an ethyl group is bound at the third carbon position — achieving solubility in both water and oil phases, and full photostability. It is absorbed into the skin and metabolised to pure Ascorbic Acid, with particularly strong clinical evidence for skin tone brightening. It provides the stable, sustained Vitamin C activity that complements the more potent but less stable pure Ascorbic Acid
• Ascorbyl Glucoside: A glucose-stabilised Vitamin C derivative — very gentle, highly stable, and well-tolerated by sensitive skin. In-vitro studies demonstrate that it is absorbed into the skin and converted to pure Vitamin C, exhibiting antioxidant protection, collagen-boosting, and hyperpigmentation-fading activity. Its gentle nature makes it ideal for delivering Vitamin C benefits without the tingling or irritation that can accompany high-concentration pure Ascorbic Acid

This triple-Vitamin C system is synergistically stabilised by the classic Vitamin C + Vitamin E + Ferulic Acid antioxidant complex: Tocopherol (Vitamin E) regenerates oxidised Vitamin C back to its active form, extending its active lifespan in the formula. Ferulic Acid — a plant-derived hydroxycinnamic acid antioxidant — doubles the photoprotective activity of the Vitamin C + E combination (as demonstrated in a landmark 2005 study) and physically stabilises the Vitamin C molecule against oxidative degradation, extending shelf-life and on-skin efficacy.

Niacinamide + Acetyl Glucosamine — Synergistic Dark Spot Duo

Niacinamide (Vitamin B3) inhibits the transfer of melanosomes (melanin-containing vesicles) from melanocytes to surrounding keratinocytes — interrupting the distribution of existing pigment across the skin surface. This mechanism is distinct from tyrosinase inhibition and operates at a different step in the pigmentation pathway, making Niacinamide complementary rather than redundant alongside the Glutathione and Vitamin C brighteners. Additionally, Niacinamide stimulates ceramide synthesis in the skin, strengthening the barrier lipid matrix to reduce TEWL and improve overall skin resilience.

Acetyl Glucosamine is an amino sugar (N-acetyl-D-glucosamine) found naturally in the skin as a biosynthetic precursor to hyaluronic acid — supporting both hydration and barrier function. Clinically, it has been shown to inhibit glycosylation of tyrosinase (a post-translational modification required for full tyrosinase enzymatic activity), reducing melanin production at yet another distinct pathway point. Double-blind clinical evidence demonstrates that Acetyl Glucosamine is synergistic with Niacinamide for dark spot reduction — the combination achieving greater hyperpigmentation improvement than either ingredient alone.

Triple Centella Asiatica Complex — Soothing + Melanin Suppression + Collagen Synthesis

Three forms of Centella Asiatica provide a comprehensive triterpenoid complex that addresses the inflammatory component of hyperpigmentation alongside barrier repair and anti-aging benefits:

• Centella Asiatica Leaf Extract: Full-spectrum leaf extract providing the complete range of Centella triterpenoids and their glycosides — Asiaticoside, Asiatic Acid, Madecassoside, and Madecassic Acid — in their natural ratios, along with supportive polyphenols and antioxidants
• Madecassoside: Isolated pure Madecassoside — a glycoside of Madecassic Acid. Clinical in-vivo studies demonstrate that 0.05% Madecassoside applied twice daily for 8 weeks produces measurable inhibition of UV-induced melanin synthesis, making it a meaningful anti-hyperpigmentation active beyond its well-known anti-inflammatory and barrier-repair properties. It also inhibits NF-κB signalling, directly counteracting the inflammatory cascade that drives post-inflammatory hyperpigmentation (PIH) after acne or sun damage
• Asiaticoside: Activates fibroblast proliferation and stimulates production of glycosaminoglycans (GAGs, including hyaluronic acid) and Collagen Type I in the dermis — contributing anti-aging firmness and hydration benefits alongside the brightening-focused actives

Barrier Repair Matrix — Ceramide NP, Cholesterol, Beta-Glucan

Ceramide NP (Ceramide 3) and Cholesterol together replicate the essential lipid components of the stratum corneum’s lamellar lipid matrix — where ceramides constitute approximately 50% and cholesterol approximately 25% of the intercellular lipid content. Their presence in this serum ensures that the intensive brightening actives (particularly Vitamin C and Lactic Acid) do not compromise barrier function during use, actively replenishing the lipids that sustain moisture retention and barrier integrity. Beta-Glucan — a yeast-derived polysaccharide — provides potent soothing and wound-healing support with proven penetration into the dermis, measurably reducing wrinkle depth and skin roughness while calming any potential sensitivity triggered by the active-dense formula.

Supporting Actives

Adenosine (KFDA-approved anti-wrinkle active) contributes cell-communicating collagen synthesis, anti-inflammatory activity, and barrier repair. Lactic Acid provides mild AHA exfoliation — accelerating the turnover of pigmented surface keratinocytes to progressively lighten the appearance of existing dark spots. Malus Domestica Fruit Cell Culture Extract (PhytoCellTec) supplies apple stem cell antioxidants including Phloridzin, Chlorogenic Acid, and Quercetin glycosides for additional oxidative stress protection. Chitosan — a cationic polysaccharide derived from crustacean shells — forms a protective film on the skin surface, provides mild antimicrobial activity against C. acnes, and enhances the formula’s substantivity. Chlorella Vulgaris Extract (green microalgae) contributes chlorophyll, amino acids, and growth factors supporting cellular regeneration.

How to Use

After cleansing and applying toner, dispense an appropriate amount of serum and gently pat across the face for even absorption. Due to the high concentration of brightening actives — particularly Vitamin C and Lactic Acid — evening use is recommended to maximise efficacy and minimise potential photosensitivity. Follow with moisturiser and, in the morning, always apply broad-spectrum sunscreen over completed skincare.
