Vivant 4% Mandelic HA Serum – 30 mL

Gentle Resurfacing, Hydration and Peptide Care in One Daily Serum

Vivant 4% Mandelic HA Serum is a gentle, multi-action treatment created for skin that needs clearer pores, smoother texture and a brighter appearance—without the intensity commonly associated with stronger exfoliating acids.

Formulated with 4% Clinical Mandelic Acid, Hyaluronic Acid, Niacinamide and advanced Peptides, it gently removes surface build-up while replenishing hydration and supporting firmer, more resilient-looking skin.

The balanced formula makes it an ideal introduction to active skincare for sensitive skin, first-time acid users or anyone who finds stronger exfoliating serums too drying. With consistent use, the complexion appears smoother, clearer, more even and naturally radiant.

What Makes the Formula Different?

Unlike traditional exfoliating serums that focus primarily on removing dead skin, Vivant 4% Mandelic HA Serum combines gentle resurfacing with hydration and age-supporting ingredients.

Its larger molecular structure allows Mandelic Acid to work more gradually than smaller AHAs such as Glycolic Acid. This controlled action makes it particularly suitable for sensitive, congestion-prone and melanin-rich skin that may be more vulnerable to irritation and post-inflammatory pigmentation.

The addition of Hyaluronic Acid, Natural Moisturising Factors and Peptides helps maintain skin comfort while supporting a smoother, firmer and more hydrated appearance.

Key Ingredients

4% Clinical Mandelic Acid

Vivant’s signature AHA helps lift away dead surface cells, refine uneven texture and keep congested pores looking clearer. The brand uses highly purified Clinical Mandelic Acid designed to provide effective yet controlled exfoliation.

Sodium Hyaluronate

A form of Hyaluronic Acid that attracts and retains moisture, helping the skin feel softer and appear smoother, plumper and more supple.

Advanced Peptide Complex

Includes Acetyl Hexapeptide-8, Tripeptide-10 Citrulline and Tripeptide-1 to support smoother, firmer and more resilient-looking skin.

Niacinamide

A versatile form of vitamin B3 that supports the skin barrier while helping improve the appearance of uneven tone, dullness and visible redness.

Pseudoalteromonas Ferment Extract

A marine-derived ferment with hydrating and skin-conditioning properties that helps support skin comfort and resilience.

DMAE

Provides antioxidant support and helps promote a firmer, more refreshed appearance.

Natural Moisturising Factors

Sodium PCA, Sodium Lactate, Glycine, Urea, Fructose and Inositol help maintain moisture and reduce the dry, tight feeling that can sometimes accompany exfoliation.

Recommended For

• Sensitive skin beginning an active skincare routine
• First-time Mandelic Acid or AHA users
• Combination, oily or congestion-prone skin
• Mild breakouts, blackheads or small clogged bumps
• Post-blemish marks and uneven-looking skin tone
• Rough, dull or lacklustre skin
• Dehydrated skin that still experiences congestion
• Mature or blemish-prone skin needing hydration and firmness support
• Melanin-rich skin seeking a gentler exfoliating option

4% or 8% Mandelic Acid?

Choose Vivant 4% Mandelic HA Serum if your skin is sensitive, dehydrated, new to acids or requires a gentler formula with added Hyaluronic Acid and Peptide support.

Choose Vivant 8% Mandelic Acid Serum if your skin is already accustomed to exfoliating acids and requires more intensive care for oiliness, persistent congestion, breakouts or uneven pigmentation.

The 4% formula can also be used as a comfortable long-term maintenance treatment or as a gradual introduction before progressing to the 8% serum.

How to Use

After cleansing and toning, apply a thin, even layer over the face, neck and décolletage. Allow the serum to absorb before applying moisturiser.

Begin every other day if you are new to exfoliating acids, then gradually increase to once daily as your skin develops tolerance.

Vivant recommends using this serum in the morning, particularly when a retinoid is used separately in the evening. Always complete your daytime routine with broad-spectrum sunscreen.

If dryness or irritation develops, pause for one day and resume at a reduced frequency.

Beauty Face Forever Tip

For sensitive or easily dehydrated skin, begin with two to three applications per week and pair with a calming, barrier-supporting moisturiser.

If your routine already includes Retinol, Tretinoin, AHA or BHA, introduce this serum gradually and use stronger actives at a different time of day or on alternate nights unless otherwise professionally advised.

Do not apply to freshly treated, irritated or visibly compromised skin.

The Science Behind Mandelic Acid

Mandelic Acid has been evaluated in human clinical studies for acne and post-acne pigmentation. Studies using professional-strength Mandelic Acid treatments have demonstrated improvements in inflammatory acne, congestion and post-acne discolouration, with favourable tolerability.

Vivant translates the benefits of this well-established ingredient into a gentle 4% daily formula, supported by hydrating and peptide-based ingredients for improved comfort and consistent home use.
