Susanne Kaufmann Nutrient Serum

A clinically tested restorative serum powered by NovoRetin™ and Alpine botanicals to support visible renewal, improve firmness, and strengthen skin resilience.

Susanne Kaufmann Nutrient Serum is designed as an essential daily treatment for skin experiencing dullness, dehydration, fine lines, or a gradual loss of firmness. Its lightweight formula combines a plant-derived retinol alternative with upcycled peptides, hydrating humectants, and antioxidant Alpine botanicals to support a smoother, stronger-looking complexion.

NovoRetin™, derived from mastic gum, supports the skin’s naturally occurring retinoic-acid pathways to deliver retinol-like smoothing and renewing benefits without containing retinol. Peptide-rich pine seedcake extract helps improve the appearance of firmness and elasticity, while edelweiss, Alpine rose, gentian, houseleek, and eleuthero extracts help defend against environmental oxidative stress.

Glycerin, saccharide isomerate, and sodium hyaluronate replenish hydration, while bisabolol helps maintain skin comfort. The result is skin that looks smoother, firmer, and more refined—with daily support rather than an aggressive approach to renewal.

Benefits:

• Clinically tested to improve skin firmness and elasticity
• Clinically tested to reduce the appearance of fine lines and wrinkles
• Supports the skin’s natural renewal processes
• Helps smooth and refine uneven-looking texture
• Promotes a firmer, more supple appearance
• Provides antioxidant protection against environmental stress
• Replenishes hydration without a heavy finish
• Helps strengthen the skin’s overall appearance and resilience
• Supports radiance and long-term skin vitality
• Offers retinol-like cosmetic benefits without containing retinol
• Lightweight and fast-absorbing

Recommended For:

• Fine lines and wrinkles
• Visible loss of firmness or elasticity
• Dull or uneven-looking texture
• Dehydrated or moisture-depleted skin
• Mature skin
• Skin exposed to pollution and environmental stress
• Those seeking an alternative to traditional retinol
• Normal, dry, oily, combination, or sensitive skin

Although positioned as a gentler retinol alternative, the formula contains fragrance and a small amount of alcohol. Sensitive or highly reactive skin should patch test and introduce it gradually.

Why It’s Different:

Nutrient Serum approaches visible ageing through several complementary pathways rather than relying on a traditional retinoid alone.

NovoRetin™ is derived from the resin of the mastic tree, Pistacia lentiscus. It is designed to increase the concentration of retinoic acid naturally present within the skin while slowing its degradation. This supports retinol-like benefits—including smoother texture, improved firmness, and a reduction in the appearance of fine lines—without adding retinol itself to the formula.

Upcycled pine seedcake extract supplies peptide-rich support for elasticity and texture, while a blend of Alpine botanicals helps defend the skin against oxidative stress. Hydrating humectants and soothing bisabolol help maintain comfort throughout daily use.

This is not a direct replacement for prescription retinoic acid, nor should it be expected to produce identical results. It is a refined daily option for clients seeking gradual renewal with a lower potential for dryness and visible irritation than many traditional retinoid formulas.

Clinically Tested Results:

After 28 days, Nutrient Serum was clinically shown to:

• Increase skin firmness and elasticity
• Reduce the appearance of fine lines and wrinkles
• Produce a measured improvement in firmness and elasticity in 100% of participants

In the 28-day user trial:

• 100% said their skin looked smoother
• 100% noticed an improvement in skin texture
• 100% said their skin felt stronger
• 95% noticed improved skin elasticity
• 91% said their skin felt firmer

Clinical and consumer-perception studies were each conducted over 28 days with 22 participants. Individual results may vary.

Texture & Aroma:

A lightweight, fluid serum that absorbs quickly and layers comfortably beneath moisturiser, facial oil, makeup, and sunscreen.

The formula may initially feel slightly cushioning or tacky because of its humectant-rich base, but it settles into the skin as it absorbs. It contains fragrance and is not fragrance-free.

How to Use:

1. Apply two or three drops to clean, slightly damp skin.
2. Gently press over the face, neck, and décolleté.
3. Follow with moisturiser or facial oil.
4. Use morning and evening according to skin tolerance.
5. Apply broad-spectrum sunscreen as the final step of the morning routine.

If your skin is new to renewal-focused ingredients, begin once daily or every other evening before gradually increasing use.

Loshen & Crem’s Recommendation:

This is a beautiful long-term serum for skin that feels depleted, dull, or less resilient than usual. It brings together hydration, antioxidant protection, and visible renewal without making the routine feel overly aggressive.

If traditional retinol repeatedly leaves your skin dry or uncomfortable, Nutrient Serum may be a more elegant daily alternative. Still, introduce it thoughtfully—“plant-based” does not mean biologically inactive.

For a restorative routine, cleanse with Susanne Kaufmann Soothing Cleansing Milk, apply Nutrient Serum to damp skin, and follow with Advanced Anti-Ageing Rich Cream when additional nourishment is needed.

If you already use prescription retinoids or a potent over-the-counter retinol, do not automatically layer both products. Alternate evenings initially or ask us to help structure your routine.

Frequently Asked Questions:

What does Susanne Kaufmann Nutrient Serum do?
It supports visible skin renewal, hydration, firmness, elasticity, smoother texture, and antioxidant protection against environmental stress.

Is Nutrient Serum a retinol serum?
No. It does not contain retinol, retinal, retinyl esters, or prescription retinoic acid. It contains NovoRetin™, a plant-derived active designed to support retinoic acid naturally present within the skin.

Does NovoRetin™ work like retinol?
NovoRetin™ is designed to offer similar cosmetic goals, including smoother texture, improved firmness, and reduced visible fine lines. It is not chemically identical to retinol, and the results should not be considered equivalent to prescription retinoids.

Is it gentler than traditional retinol?
It is formulated as a lower-irritation alternative and may be better tolerated by clients who find traditional retinol too drying. However, individual reactions remain possible, so sensitive skin should introduce it gradually.

Is Nutrient Serum clinically tested?
Yes. After 28 days, it was clinically shown to improve firmness and elasticity and reduce the appearance of fine lines and wrinkles. The clinical study involved 22 participants.

How quickly should I expect results?
Hydration and softness may be noticed sooner, while the clinical and consumer results for firmness, texture, and fine lines were assessed after 28 days of consistent use.

Is it suitable for sensitive skin?
The brand recommends it for sensitive skin. However, it contains fragrance and alcohol, so highly reactive or fragrance-sensitive skin should patch test before use.

Can I use Nutrient Serum every day?
Yes. It is formulated for morning and evening use. Those with sensitive skin can begin once daily or every other evening and increase gradually.

Can I combine it with retinol or prescription tretinoin?
Possibly, but layering both immediately may be unnecessary and could increase sensitivity. Begin by alternating evenings or seek personalised guidance from your dermatologist or skincare professional.

Can I use it with vitamin C, niacinamide, or peptides?
Yes. It can generally be combined with vitamin C, niacinamide, peptides, hyaluronic acid, and barrier-supporting ingredients.

Should I use sunscreen with Nutrient Serum?
Yes. Daily broad-spectrum sunscreen is essential when targeting visible ageing and supporting long-term skin health, regardless of whether a formula contains traditional retinol.

Is Nutrient Serum suitable during pregnancy or breastfeeding?
NovoRetin™ is not retinol, but it is designed to influence naturally occurring retinoic-acid pathways. Because pregnancy guidance can vary, consult your physician before introducing it during pregnancy or breastfeeding.

What is the difference between Nutrient Serum and Ectoin Repair Serum?
Nutrient Serum focuses more strongly on visible renewal, firmness, texture, and fine lines. Ectoin Repair Serum focuses on barrier support, hydration, environmental protection, and visible redness. Skin experiencing active sensitivity or barrier disruption may benefit from prioritising Ectoin Repair Serum first.

Is it fragrance-free?
No. The formula contains parfum.
