FIXDERMA Nigrifix Cream for Acanthosis Nigricans — 3.52 fl oz | Lactic Acid & Retinol Exfoliating Moisturizer for Dark Neck, Armpi

FIXDERMA Nigrifix Cream is a dermatologist-tested retinol and lactic acid formula designed to exfoliate and smooth areas of darkened, thickened skin commonly seen in body folds like the neck, armpits and elbows.

Many people notice velvety, darkened patches on locations such as the back of the neck, inner thighs, knuckles and ankles. This cream combines keratolytic and moisturizing ingredients — including lactic acid, retinol, urea and nourishing oils — to gently exfoliate surface buildup while helping the skin feel softer and hydrated. The product is presented in a 3.52 fl oz tube and is formulated to be non-greasy for everyday use.

How does Nigrifix help improve texture on thickened skin?

The cream uses lactic acid and urea to loosen and remove excess surface cells, and retinol to support skin cell turnover. Over continued use, this combination can reduce roughness and restore a smoother feel without heavy residue.

• Lactic acid: mild exfoliation of dead skin cells
• Urea: softens harder, callused areas
• Retinol: supports regulated cell renewal
• Non-greasy vehicle: leaves skin feeling light and absorbent

Can I use it on sensitive or frequently rubbed areas like the neck or armpits?

FIXDERMA Nigrifix is formulated to be non-tacky and suitable for skin folds, but areas that are frequently irritated should be monitored. Start with a small amount once daily to assess tolerance, and avoid applying to broken or actively inflamed skin.

• Patch-test first on a small area
• Apply thinly to affected folds once daily
• Avoid broken or inflamed skin and contact with eyes
• Discontinue use if persistent irritation occurs

What ingredients are responsible for hydration and comfort?

Alongside exfoliating actives, moisturizing agents such as sweet almond oil and urea balance hydration to prevent excessive dryness. Tea tree oil provides a refreshing note and contributes to overall skin comfort, while the formulation keeps a light, non-greasy finish.

• Sweet almond oil: helps retain skin moisture
• Urea: hydrates and softens thicker patches
• Tea tree oil: adds a calming aromatic component
• Non-greasy base: quickly absorbed for daily wear

How should I apply Nigrifix for best results and safety?

Clean and dry the target area before applying a sufficient amount of cream to the darkened patch and massage gently until absorbed. For visible improvement, use consistently—typically once per day—and consult a dermatologist for persistent or changing skin concerns.

• Cleanse and dry the area thoroughly
• Apply thin layer and massage until absorbed
• Use daily and observe skin response
• Seek professional advice for severe or changing lesions

Who is this for: FIXDERMA Nigrifix Cream is intended for adults looking to address thicker, darker skin in body folds and creases such as the neck, armpits, inner thighs, knuckles, ankles and elbows. It is suited to those who want a non-greasy, topical approach combining gentle exfoliation and moisturization; however, anyone with highly sensitive skin, open wounds, or ongoing dermatological conditions should consult a healthcare professional before use.
