SENSORY120h PhytoMoisture Complex
A patented blend of amylopectin from upcycled broken rice and calcium carbonate from Atlantic red algae that builds a 120-hour moisture depot in the skin after 28 days of consistent use.
Niacinamide Barrier Boost
Approximately 5% niacinamide strengthens the skin barrier, reduces redness, fades dark spots, regulates sebum production, and smooths fine lines.
Chardonnay Grape Extract
Vitis Vinifera fruit extract helps regulate the skin's internal circadian clock, supporting natural overnight regeneration and antioxidant protection.
Blue Beauty Principles
Developed with ocean safety in mind using upcycled ingredients (broken rice), microplastic-free formula, and recycled glass packaging. ISO 9001-certified production in Germany.
Safety & compatibility
SAFEContains no retinoids, salicylic acid, hydroquinone, or chemical sunscreens. Lactic acid and citric acid are present only as pH adjusters at non-active concentrations. Safe to use during pregnancy and while nursing.
Free from ferments, fatty acids, esters, polysorbates, and oils. All humectants (glycerin, diglycerin, butylene glycol) are malassezia-safe. No ingredients that feed the Malassezia yeast.
Fragrance-free, essential-oil-free, and alcohol-free formula. WIMJ rates overall irritation risk as low. Suitable for sensitive and reactive skin types.
Minimal comedogenic risk. Oil-free, lightweight formula with no known pore-clogging ingredients. Only Lithothamnion Calcareum Extract has a minor comedogenicity flag, but at low concentration it poses very little risk.
Niacinamide pairs well with retinol and vitamin C. Can be layered with most actives. Apply this serum first, wait 1-2 minutes, then apply retinol or vitamin C products on top.
Some users report a mild tingling or warmth upon first use, especially on compromised skin barriers. This typically resolves within the first week. Patch test recommended for very reactive skin.
Ingredient breakdown
INGREDIENTSNiacinamide (Vitamin B3) ~5-8%Proven
A multifunctional powerhouse backed by extensive clinical research. Strengthens the skin barrier by boosting ceramide synthesis, reduces hyperpigmentation, minimizes pore appearance, regulates sebum, and smooths fine lines.
- Barrier: Increases ceramide production, leading to stronger, more resilient skin
- Brightening: Inhibits melanosome transfer to reduce dark spots at 4-5% concentration
- Anti-Aging: Clinically shown to reduce fine lines and wrinkles with regular use
- Sebum Control: Regulates oil production, beneficial for oily and combination skin
Amylopectin (PhytoMoisture Complex) ~2-4%Promising
Sourced from upcycled broken rice grains. Forms part of the proprietary PhytoMoisture complex. Works with calcium carbonate from red algae to create a long-lasting moisture reservoir in the skin over 28 days of use.
- Source: Upcycled from rice bran that would otherwise be discarded (Blue Beauty principle)
- Mechanism: Gradually builds a hydration depot within the upper skin layers
- Claim: 120-hour continuous moisture delivery after 28 days of daily application
Lithothamnion Calcareum Extract ~1.4-2%Promising
Calcium carbonate derived from sustainably cultivated Atlantic red algae. Rich in marine minerals, it works alongside amylopectin to form the PhytoMoisture complex, helping the skin retain moisture over extended periods.
- Source: Sustainably harvested Atlantic red algae (Lithothamnion calcareum)
- Benefits: Mineral-rich extract that aids moisture retention in the upper skin layers
- Sustainability: Sourced from renewable marine resources in alignment with Blue Beauty standards
Vitis Vinifera (Grape) Fruit Extract ~1%Promising
Chardonnay grape extract that provides antioxidant protection and helps regulate the skin's circadian rhythm. Supports overnight skin regeneration and helps neutralize free radical damage.
- Antioxidant: Polyphenols from grapes help protect skin cells from oxidative stress
- Circadian Support: May help regulate the skin's internal clock for better overnight repair
- Hydration: Acts as a humectant, helping attract water to the skin's surface
Glycerin & Diglycerin ~3-5%Proven
Two forms of one of the most effective humectants in skincare. Glycerin is naturally present in the skin and draws moisture from the environment into the upper skin layers. Diglycerin provides extended humectant action.
- Comedogenicity: 0 — does not clog pores
- Irritancy: 0 — extremely well-tolerated by all skin types
- Function: Attracts and binds water for immediate and lasting hydration

Where it fits in your routine
ROUTINEBest used in the evening. Mix 2-3 drops into your night cream or apply directly to cleansed skin before moisturizer. Pairs perfectly with the Nø Rain Today 120h HyperMoisture Cream.
How to use
HOW TO USECleanse Your Skin
Start with a clean face. Use your preferred gentle cleanser and pat dry with a soft towel.
Apply 2-3 Drops
Dispense 2-3 drops of the serum onto your fingertips. A little goes a long way — the 20 ml bottle lasts 2-3 months with nightly use.
Mix or Layer
Either mix the drops directly into your evening moisturizer, or apply the serum first to your face and neck, then follow with cream. Both methods work equally well.
Seal with Moisturizer
Lock in the serum with a moisturizer or sleeping mask. The PhytoMoisture complex works best when sealed under an occlusive layer to prevent transepidermal water loss.

- You want deep, long-lasting hydration without heaviness
- You have redness, uneven skin tone, or hyperpigmentation
- You prefer fragrance-free, clean beauty formulas

- You care about sustainability and eco-conscious packaging
- You want a simple, effective niacinamide serum at a mid-range price

Consider alternatives if:
- You need maximum oil control (The Ordinary Niacinamide 10% + Zinc 1% may be more effective)

Skin type compatibility
SKIN TYPESLightweight and oil-free. Niacinamide helps regulate sebum production. Won't add shine, but those with very oily skin may prefer a formula with added zinc.
Glycerin, diglycerin, and the PhytoMoisture complex deliver intense long-term hydration. Layer under a rich cream for best results on very dry skin.
Balances well across different face zones. Hydrates dry areas without overloading oily zones. Niacinamide works on both concerns simultaneously.
Fragrance-free, essential-oil-free, minimal ingredient list of only 18 ingredients. Low irritation potential. Patch test for very reactive skin as mild tingling may occur initially.
Non-comedogenic (1/5), fungal-acne-safe, and oil-free. Niacinamide helps reduce blemishes and post-inflammatory redness. Not a targeted acne treatment, but supportive.

Criticized
- Small 20 ml bottle — may seem expensive per ml (€74.75/100ml)
- Some users experience mild tingling or skin peeling in the first few days
- Requires 28 days of daily use to reach full PhytoMoisture effect
- Limited international availability (primarily sold in EU/Germany)
- Glass dropper bottle can be fragile and not the most travel-friendly
- No added zinc for extra oil control compared to some competitors
Budget-friendly alternatives (dupes)
DUPESHigher niacinamide concentration (10% vs ~5%) with added zinc for oil control. Simpler formula without the PhytoMoisture complex or grape extract. More viscous texture. Better for oily/acne-prone skin, but lacks the long-term moisture-depot benefit.
10% niacinamide with added glycerin and betaine for extra moisture. Slightly more hydrating than The Ordinary but still lacks the unique PhytoMoisture complex. Larger 30 ml bottle offers better value per ml. Good middle-ground option.
10% niacinamide with 1% hyaluronic acid for hydration support. Gentler formula that some find less irritating. Lacks the sustainability focus and proprietary moisture-depot technology. Better for niacinamide beginners.

Frequently asked questions
FAQYes. This serum contains no retinoids, salicylic acid, hydroquinone, or chemical sunscreens. The lactic acid and citric acid present are used only as pH adjusters at non-active concentrations and are not a concern during pregnancy or breastfeeding. All ingredients are considered safe for use by pregnant and nursing individuals. As always, consult your healthcare provider if you have specific concerns.
Yes. This formula is free from ferments, fatty acids, esters, polysorbates, and oils — all common triggers for fungal acne. The humectants used (glycerin, diglycerin, butylene glycol, pentylene glycol) are all malassezia-safe. This makes it one of the safer niacinamide serums available for those prone to fungal acne.
Yes. Niacinamide is highly compatible with most actives, including retinol, vitamin C (L-ascorbic acid), AHAs, and BHAs. The old myth that niacinamide and vitamin C cancel each other out has been debunked. You can safely layer this serum with these actives. Apply the thinnest product first (usually this serum), wait 1-2 minutes, then follow with your other treatments. If using retinol, this serum can actually help buffer potential irritation from retinoids.
This serum is designed for all skin types but excels for combination, dry, and sensitive skin. Its lightweight, oil-free formula absorbs quickly without greasiness, making it suitable for oily skin as well. The fragrance-free, minimal-ingredient formula makes it particularly well-suited for sensitive and reactive skin. Those with very oily skin focused primarily on oil control may prefer a formula with added zinc.
Initial hydration benefits are noticeable within the first week — skin feels softer and more supple. Visible improvements in redness and texture typically appear at weeks 2-3. The full PhytoMoisture complex effect (120-hour moisture depot) requires 28 days of consistent daily use. Maximum benefits from niacinamide for brightening and anti-aging accumulate over 6-8 weeks of nightly application.
Apply this serum after cleansing and toner, but before moisturizer. It fits at Step 3 in a typical skincare routine. Best used in the evening (PM). You can either apply 2-3 drops directly to your face, or mix the drops into your evening moisturizer. Always follow with a moisturizer to seal in the serum. If using in the morning, apply before sunscreen.
This serum has a very low comedogenic rating of 1 out of 5. It is oil-free, silicone-free, and contains no known pore-clogging ingredients at significant concentrations. The only ingredient with a minor comedogenicity flag (Lithothamnion Calcareum Extract) is present at less than 2%, which poses minimal real-world risk of clogging pores. This makes it suitable for acne-prone and breakout-prone skin.
The Period After Opening (PAO) is 12 months. Despite the small 20 ml bottle, the product lasts approximately 2-3 months with nightly use of 2-3 drops. Store in a cool, dry place away from direct sunlight. The preserved formula (phenoxyethanol + ethylhexylglycerin + potassium sorbate + sodium benzoate) ensures stability throughout the PAO period.
Verdict: The Nø Rain Tonight 120h HyperSleep Serum is a thoughtfully formulated, clean German beauty serum that delivers genuine hydration and skin-barrier benefits through clinically backed niacinamide and an innovative PhytoMoisture complex. Its fragrance-free, minimal-ingredient formula makes it safe for pregnancy, fungal acne, and sensitive skin — a rare combination at this price point. The main drawback is the small 20 ml bottle size, which may feel premium-priced compared to larger competitors. However, the unique 120-hour moisture-depot technology, sustainable Blue Beauty philosophy, and ISO-certified German manufacturing set it apart. Ideal for anyone seeking a gentle yet effective niacinamide serum that prioritizes skin compatibility and environmental responsibility.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
