Anti-Aging Neck & Decolletage Cream

Serenity Age Neck & Decolletage Cream is BIOSAR's targeted anti-age cream for the neck and chest, areas that show time as visibly as the face but receive less daily care. Peptides support firmness and contour along the jawline; Hyaluronic Acid restores hydration; Vitamin E supports daily defense. Use it morning and night with upward sweeping strokes from chest to jaw. The cushiony texture absorbs cleanly under sunscreen and clothing. Suitable for mature skin and earlier-prevention routines from the mid-thirties onward. Pairs with any Serenity Age face cream.

Why it works

Proven Benefits

What this product does for your skin

  • Firmer neckline

    Peptides support firmer-looking contour along the neck and jawline.

  • Replenished comfort

    Hyaluronic Acid restores hydration to the neck and chest.

  • Smoother decollete

    Targeted care softens the look of crepey chest and neck skin.

  • Antioxidant support

    Vitamin E supports the neck area against daily oxidative stress.

How this formula works

The neckline lifted, smoothed, and left as at ease as the face above it

The neck and décolletage ask for firming with a soft hand, and this cream answers with both. Lactic Acid and AHA smooth and refine that delicate skin, while Algae Extract and Palmitoyl Tetrapeptide-7 stay close to keep it supple and comfortable through the process. Caffeine adds a toned, defined feel, so the whole area looks firmer and reads as cared for, not stressed.

Ingredient Research

Active ingredients backed by published studies

  • 12 weeks

    Fewer fine lines than the same moisturiser without it

    A double-blind split-face trial in 93 women aged 35 to 55: a moisturiser with palmitoyl pentapeptide, used for 12 weeks, reduced wrinkles and fine lines versus the same moisturiser without it, by image analysis and expert grading.

What's inside — and what's not

  • 01

    Caffeine

    Stimulant that supports local microcirculation where it is applied. In body and eye-area formulas it helps de-puff and firm the look of skin, for a smoother, more toned and visibly refreshed appearance.

  • 02

    Peptides

    Palmitoyl Tripeptide-1

    Short chains of amino acids that act as messengers in the skin. In anti-aging formulas they support the signals behind firmness and elasticity, softening the look of fine lines for smoother, more resilient skin.

  • 03

    Palmitoyl Tetrapeptide-7

    As a peptide, it sends supportive messenger-style signals that help reinforce the appearance of firmness and smoothness.

  • 04

    Algae Extract

    Its marine minerals and sugars condition and replenish the surface, helping skin feel soft and supple.

    View research
  • 05

    Lactic Acid

    It loosens bonds between surface cells to ease gentle exfoliation while drawing in moisture for a smoother look.

    View research
  • 06

    AHA

    Alpha Hydroxy Acids

    They dissolve the bonds holding loose surface cells, supporting gentle exfoliation and surface renewal.
