When it comes to skincare powerhouses, Estee Lauder’s Advanced Night Repair Serum (also known as ANR) reigns supreme.

Let’s take a closer look at the ingredients that make this cult-favorite serum a gold standard in anti-aging skincare. Estee Lauder Advanced Night Repair
Understanding the Formula
Estee Lauder is known for its innovative skincare science, and ANR is no exception. Its formula revolves around supporting the skin’s natural nighttime repair process, hydrating deeply, and protecting against environmental stressors. Whether you have dry, oily, sensitive, or combination skin, this serum is designed to restore balance and promote a radiant glow.
Key Active Ingredients
- Bifida Ferment Lysate
Let’s start with the star player. This probiotic-derived ingredient helps enhance the skin’s barrier function, making it more resilient to damage from UV light and environmental pollutants. Think of it as a personal trainer for your skin’s defense system.
- Tripeptide-32
Little peptide is all about timing. It helps regulate the skin’s natural circadian rhythm, which means it encourages your skin to repair itself more efficiently at night, when your body naturally works to heal and regenerate.
- Sodium Hyaluronate
You might know this as a relative of hyaluronic acid—and yes, it’s just as moisturizing, if not more. It penetrates deeper and delivers intense hydration that plumps the skin and reduces the appearance of fine lines.
- Lactobacillus Ferment
Another fermented gem that brings probiotic benefits to your skin. It helps balance the microbiome and strengthens the skin’s natural immunity, making it ideal for anyone dealing with redness, sensitivity, or breakouts.
- Squalane
This plant-based lipid mimics the skin’s natural oils and provides deep hydration without clogging pores. It’s also known for soothing dry and inflamed skin.
- Tocopheryl Acetate (Vitamin E)
Vitamin E is a potent antioxidant that helps repair damaged skin and protect against future damage from free radicals.
Supporting Ingredients That Make a Difference
Caffeine
Not just for your morning cup—caffeine in skincare reduces puffiness and redness while stimulating circulation for a healthier, more awake appearance.
Yeast Extract
A skin conditioner that’s packed with minerals and amino acids, yeast extract boosts cellular regeneration and energizes tired skin.
Chamomile (Anthemis Nobilis) Extract
Known for its soothing properties, chamomile extract is a great addition to ANR, calming irritated skin and reducing inflammation. Estee Lauder Advanced Night Repair
Safe Preservatives and Stabilizers
Phenoxyethanol
Used to ensure the product stays bacteria-free, this is a safe and commonly used preservative in modern cosmetics.
Potassium Sorbate and Sodium Benzoate
These ingredients help extend shelf life and keep the formula fresh. They’re both considered safe in the small amounts used in skincare.

Texture and Delivery System
What makes ANR special is its lightweight, fast-absorbing texture. It doesn’t sit on your skin or feel greasy—perfect for layering with other products like moisturizers and even makeup.
What It Doesn’t Contain
One of the big draws of ANR is what’s not in the bottle:
No synthetic fragrance
parabens
sulfates no
phthalates
This makes it suitable for sensitive skin and those who prefer clean beauty formulations.
The Science Behind Synchronization
Estee Lauder’s “Chronolux™ Power Signal Technology” is built on years of research. This technology helps skin sync with its natural repair processes, optimizing results during your body’s rest-and-repair cycle at night.

Ingredient Synergy
One of the magical things about this serum is how the ingredients work together. Each one supports the others—hydration, repair, protection, and anti-aging benefits all rolled into one bottle. You’ll notice:
Fewer fine lines
Improved tone and texture
More bounce and glow
But consistency is key. Use it nightly and be patient. You’ll thank yourself in 3 weeks.
Who Should Use It?
Honestly? Just about anyone.
Teens looking to start an anti-aging routine early
Adults facing fine lines, dullness, or dehydration
Sensitive skin types need soothing care
Men and women alike—this isn’t a gendered product
It’s ideal to start using ANR in your mid-to-late 20s, but there’s no wrong time to start. The earlier, the better.
