Sereko Hydra-crème offers a pleasant, hydrating experience with good soothing properties, but its most ambitious claims, particularly the '100H' duration, are not fully substantiated by finished product clinical evidence.
The Sereko Hydra-crème is positioned as a barrier-repairing and hydrating moisturizer, which is highly relevant for Indian consumers facing diverse climates and potential barrier damage from pollution or strong actives. Its gel-cream texture is suitable for India's often humid conditions, preventing a heavy feel. While the '100H Hydration' claim is ambitious and lacks specific finished product clinical backing, the product does provide good hydration and soothing benefits, supported by clinical testing for sensitive skin. The pricing, while initially premium, becomes competitive with frequent discounts on major Indian e-commerce platforms. The brand's 'NeuroCalm(S)® Formula' claims are broad and ingredient-level, which ASCI might scrutinize if presented as finished product benefits without specific evidence.

We checked the ingredient list, publicly available test reports, marketing claims, and formula logic using only public information available at the time of analysis.
Ceramides are known to support skin barrier repair, but their position low in the INCI suggests lower concentration. No finished product study specifically on barrier repair is publicly visible.
A consumer perception study (30 respondents, 4 weeks) states '96% of users said their skin felt instantly hydrated after just one use.' This supports immediate hydration, but not the '100H' duration. The FAQ explains the mechanism but lacks clinical data for the 100H claim.
A clinical study by Mascot Spincontrol (07/03/2025 - future date) on 'Dermatological Safety & Irritation Potential' states the product is 'Non-irritant to sensitive skin' and 'Suitable for Sensitive Skin'.
Ceramides are present and known for barrier support, but their concentration is likely low. No finished product study specifically on treating a damaged barrier is publicly visible.
Supported by the consumer perception study showing 96% of users felt instantly hydrated. Humectants like Glycerine and Aquaxyl™ are high in the INCI.
A clinical study by Mascot Spincontrol states the product is 'Suitable for Sensitive Skin' and 'Non-irritant'.
A clinical study by Mascot Spincontrol states the product is 'Non-irritant to sensitive skin'.
Ingredients like Centella Asiatica Extract and Aloe Barbadensis are known for soothing properties that can help reduce redness, but no finished product evidence for redness reduction is publicly visible.
Ceramides (NP, AP, AS, NG, EOP) are present in the INCI, but their position after Phenoxyethanol suggests concentrations below 1%. General ingredient research supports their role in barrier repair.
Peptides (Palmitoyl Tripeptide-1, Palmitoyl Tripeptide-7) are present, but low in the INCI. A consumer perception study noted '88% of users said that their skin felt noticeably plumper.'

How we read this product across five areas. Open any row for the full reasoning.
Micro Marine Algae: Active · Claimed as an antioxidant, it can offer skin protection and hydration.
Wild Indigo: Active · An extract (Tephrosia purpurea) often associated with stress-reducing and calming effects on the skin, part of the NeuroCalm(S)® blend.
CI 42090: Colorant · A blue synthetic dye used to give the product its color.
Ocimum Basilicum: Active · Basil extract, which can have soothing and antioxidant properties, potentially part of the NeuroCalm(S)® blend.
The formula is a well-constructed gel-cream with a strong humectant base (Glycerine, Butylene Glycol, Propanediol, Aquaxyl™ components) that supports its primary hydration claims. The presence of multiple ceramides, peptides, and soothing botanical extracts (Centella, Aloe) aligns with barrier repair and calming claims. However, the lower placement of ceramides and peptides in the INCI suggests their concentrations might be less impactful for intensive 'repair' compared to the prominent humectants for 'hydration'. The gel texture is appropriate for a lightweight, non-greasy feel.
While humectants like Glycerine and Aquaxyl™ are high in the INCI, the '100H Hydration' claim is ambitious for a cosmetic moisturizer without robust finished product clinical data. Ceramides and Peptides, while present, appear after the 1% preservative line, suggesting lower concentrations than might be ideal for headline 'repair' claims. The 'NeuroCalm(S)®' claims for cortisol reduction are likely ingredient-level, not finished product.
