Use With Caution
Chapter II · The Ingredients
We scored every ingredient individually. Some impressed us. Others raised serious questions.
Bifida Ferment Lysate
A probiotic that supports the natural repair of the skin barrier and cell renewal.
Caprylic/Capric Triglyceride
A highly compatible neutral oil derived from coconut fat, which makes the skin smooth and nourishes it.
Dimethicone
A silicone oil that provides a smooth texture but can occlusively seal the skin.
Nylon-12
Considered a solid microplastic that pollutes the environment and merely improves the product's texture.
Bis-PEG-18 Methyl Ether Dimethyl Silane
A water-soluble silicone/PEG derivative that can make the skin barrier more permeable to other active ingredients.
Glycerin
A proven moisturizer that binds water in the upper skin layers and strengthens the skin barrier.
Sodium Hyaluronate
A highly effective moisture magnet that plumps the skin and protects it from dehydration.
Tripeptide-32
A peptide that supports the skin's regeneration processes and improves the appearance of fine lines.
Squalane
A valuable, skin-identical lipid that intensively nourishes the skin without clogging pores.
BHT
A synthetic antioxidant suspected of having hormonal effects and polluting the environment.
Disodium EDTA
A chelating agent that improves stability but is hardly biodegradable in the environment.
Phenoxyethanol
A common preservative that can rarely cause skin irritations.
Sodium Metabisulfite
A preservative that can cause allergic reactions in sensitive individuals.
Caffeine
Stimulates blood circulation and has antioxidant properties to prevent skin aging.

Chapter III · The Deep Dive
The Estée Lauder Advanced Night Repair Serum is a regenerating facial serum that aims to strengthen the skin barrier and minimize the signs of aging during nighttime rest.
The formulation combines high-quality biotechnological active ingredients such as probiotics and peptides with proven moisturizers. Nevertheless, the product contains several synthetic substances like silicones, microplastics, and the controversial antioxidant BHT, which lowers the overall rating with regard to environmental impact and ingredient purity.
| Ingredient | Rating | Function & Effect |
|---|---|---|
| Bifida Ferment Lysate | 🟢 | A probiotic that supports the skin's repair mechanisms and strengthens the barrier. |
| Caprylic/Capric Triglyceride | 🟢 | A well-tolerated neutral oil that nourishes and smooths the skin. |
| Dimethicone | 🟡 | A silicone oil that provides a silky skin feel but can occlusively seal the skin. |
| Nylon-12 | 🔴 | A synthetic polymer that serves as an opacifying agent and is considered a solid microplastic. |
| Bis-PEG-18 Methyl Ether Dimethyl Silane | 🟡 | A water-soluble silicone/PEG derivative that can make the skin more permeable to other substances. |
| Glycerin | 🟢 | A classic humectant that helps bind water in the skin. |
| Sodium Hyaluronate | 🟢 | The salt of hyaluronic acid, an excellent moisture magnet for the upper skin layers. |
| Tripeptide-32 | 🟢 | A peptide that supports skin conditioning and aids in cell renewal. |
| Squalane | 🟢 | A skin-identical lipid that makes the skin supple without being greasy. |
| Caffeine | 🟢 | Stimulates microcirculation and possesses antioxidant properties. |
| BHT | 🔴 | A synthetic antioxidant suspected of being hormonally active and polluting the environment. |
| Disodium EDTA | 🟡 | A chelating agent that increases stability but is poorly biodegradable in the environment. |
| Phenoxyethanol | 🟡 | A common preservative that can be irritating in high concentrations. |
The product's environmental footprint is to be considered critically due to some synthetic components.
Conclusion: The serum offers a complex blend of nourishing extracts, probiotics, and moisturizers that can effectively combat dryness and fine lines. However, points are deducted for the use of BHT, microplastics (Nylon-12), and silicones, which offer no real added value for either skin physiology or the environment.
Recommendation:
High Concern — Flagged Ingredients
Nylon-12
Considered a solid microplastic that pollutes the environment and merely improves the product's texture.
BHT
A synthetic antioxidant suspected of having hormonal effects and polluting the environment.
