Codex Labs enriches their BIA cosmetics range for fragile skins, along the new KĀNGFÙ line, as any post-aggression treatments

In 2026, Codex Labs strengthens its holistic approach to skin health by evolving their BIA range toward a sort of inside and out strategy. By combining targeted nutrition, but also gut microbiome balance, and dermatological skincare, the brand supports all fragile skins from the earliest age. From dietary supplements to soothing cosmetic formulas, Codex Labs delivers a scientifically grounded and cohesive response to durably reinforce the skin barrier. By AL & ST

As you can see, Codex Labs is evolving their BIA range by integrating a nutritional dimension, designed for all types of fragile skins from the earliest age. Already recognized for their various moisturizing skincare lines, adapted to dry, sensitive, or eczema-prone skins, this BIA range now welcomes a dietary supplement for infants and young children, aged 4 to 12, the BIA Kids Skin Barrier Support supplement comes in a chewable gummy format for simplified daily use. Its formula combines L-histidine, vitamins D and E, biotin, and zinc, all nutrients studied for their role in supporting your skin barrier and comfort of sensitive skins. A nutritional and appealing approach, red-berry flavored, designed to strengthen all skin’s natural defenses, from childhood phase.

L-histidine is an essential amino acid, involved in immune function and skin health, particularly important for maintaining the integrity of your skin barrier.

Also intended for children, from 6 months to 3 years, the BIA Dietary Supplement – Infants & Children. Its formula combines L-histidine, vitamins C and E, niacin, biotin, and zinc—micronutrients, all involved in immunity, cellular protection, and skin balance. Presented as a powder with no added flavorings or preservatives, the product aims to support your skin barrier by promoting the synthesis of filaggrin, a key protein for hydration. Easy to mix into daily food, it positions itself as an early support to help limit dryness, discomfort, and irritation, while respecting the nutritional needs of toddlers (photo credits: Codex Labs).

L-histidine plays a key role in the production of filaggrin, a protein essential for skin hydration, protection, and resilience, especially in sensitive or eczema-prone epidermis.

Still in powder shape, conceived as inner care, the BIA Prebiotic Dietary Supplement – Intestinal Microbiome targets this time the balance of the gut microbiome, now recognized for its influence on skin health. Its plant-based formula combines L-glutamine, chicory fibers, and resistant starch to support digestion, and even strengthen your intestinal barrier, and soothe your mucosa. It can be used alone or in synergy with ClearSkin solutions, as part of a holistic gut–skin approach.

L-glutamine is a key amino acid that supports intestinal barrier integrity, immune function, and overall skin balance via the gut–skin combination..

Furthermore, with its BIA ClearSkin synbiotic supplement, once again Codex Labs tend to target eczema-prone skins, through this gut–skin axis. This capsule based formula combines three probiotic strains, rich in prebiotic blueberry to rebalance your microbiome, while reducing random digestive inflammations, plus support your skin barrier. A nutritional strategy that leverages gut health to stabilize your skin over some long term period.

The gut–skin axis refers to the close interaction between the intestinal microbiome, immune system, and skin health, whereby gut imbalance can contribute to inflammation and skin disorders.

In addition, presented as the cosmetic innovation of this range, the BIA Ultra-Soothing Lotion targets dry, sensitive, or again eczema-prone skins. Its fast-absorbing formula, enriched with BiaComplex® 2.0 patented molecule, along colloidal oatmeal, hyaluronic acid, and ceramides, promises some true intense hydration and reinforcement of your skin barrier. As far as we know, various clinical tests report a significant reduction in itching and signs of irritation, within a few weeks.

Finally, in the new KĀNGFÙ category, positioned as a post-aggression treatment, the KĀNGFÙ Gel is notably designed for skins, that may have been sensitized by sun exposure or aesthetic procedures. Inspired by traditional Chinese medicine and enriched with antioxidant complexes, its formula aims to soothe redness and overheating, while preserving hydration. Here as well, clinical data indicate a measurable improvement in skin comfort within just a few days.
