Frequently Asked Questions
About Kure Niva Products
What is NAD+ and why is it in skincare?
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme present in every living cell, playing a critical role in cellular energy production, DNA repair, and metabolic function. In skincare, topically applied NAD+ helps support skin cell vitality and promotes a more youthful-looking appearance. NAD+ levels decline naturally with age — supplementing the skin with NAD+ may help support its natural renewal processes.
What are peptides and what do they do for skin?
Peptides are short chains of amino acids — the building blocks of proteins like collagen and elastin. In skincare, bioactive peptides act as cellular messengers, signaling skin to support its structural proteins, improve firmness, and reduce the appearance of fine lines and wrinkles. Kure Niva products contain 9 to 50 different peptides per formula, each selected for specific anti-aging benefits.
What is NMN and how does it relate to NAD+?
NMN (Nicotinamide Mononucleotide) is a direct precursor to NAD+ in the body's natural biosynthesis pathway. Topical application of NMN may help support the skin's ability to maintain NAD+ levels, supporting cellular energy and skin vitality. The Kure Niva NAD+ Peptide Renewal Serum contains both NAD+ and NMN for a dual-pathway approach.
What is the difference between the NAD+ Peptide Renewal Serum and the NAD+ Retinol Volumizing Cream?
The NAD+ Peptide Renewal Serum is a lightweight serum designed for daily use by all skin types — focusing on firming, hydration, fine line reduction, and overall skin renewal. The NAD+ Retinol Volumizing Cream is a richer cream specifically targeting volume loss, deep wrinkles, and skin density. Together they form a complete anti-aging routine.
Can I use both products together?
Absolutely. Apply the NAD+ Peptide Renewal Serum first on clean skin, allow it to absorb, then follow with the NAD+ Retinol Volumizing Cream. Use morning and evening for the serum; use the Volumizing Cream primarily in the evening (retinol increases sun sensitivity).
Skin Concerns
Which product is best for fine lines and wrinkles?
Both products address fine lines and wrinkles, but differently. The NAD+ Peptide Renewal Serum is ideal for early-to-moderate fine lines, targeting surface smoothing and hydration. The NAD+ Retinol Volumizing Cream is better for deeper wrinkles and volume loss, with retinol actively promoting cell turnover and collagen support.
Which product is best for dry or dehydrated skin?
The NAD+ Peptide Renewal Serum contains a hydrating actives complex designed to deliver deep, long-lasting hydration. Suitable for dry, dehydrated, and combination skin types.
Which product is best for skin that has lost volume or firmness?
The NAD+ Retinol Volumizing Cream is specifically formulated for this concern. Its 50-peptide complex and retinol work to support the skin's structural matrix and restore a fuller, more lifted appearance over time.
Usage & Safety
Is retinol safe for daily use?
Retinol is highly effective but can cause irritation when first introduced to a skincare routine. We recommend starting with every-other-night application and gradually increasing to nightly use as your skin adjusts. Always apply SPF 30+ sunscreen during the day when using retinol products, as retinol increases photosensitivity.
Are Kure Niva products suitable for sensitive skin?
The NAD+ Peptide Renewal Serum is gentle enough for sensitive skin. The NAD+ Retinol Volumizing Cream contains retinol, which may cause sensitivity — we recommend a patch test and gradual introduction. Consult your dermatologist if you have specific skin conditions.
How long before I see results?
Hydration and skin radiance improvements are often visible within the first 1–2 weeks. Significant reductions in fine lines, improved firmness, and volume restoration typically become noticeable after 4–8 weeks of consistent daily use. Individual results vary based on skin type, age, and consistent usage.
