Morning routine
Apply with upward sweeping strokes from chest to jaw. Allow thirty seconds to absorb before clothing.

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.
Firm, lift and smooth the area that shows age first. Palmitoyl Tetrapeptide-7 and Algae Extract firm and tone while Lactic Acid and AHA refine texture and Caffeine energizes, giving the neck and decolletage a visibly firmer, smoother look over 6 to 8 weeks.
Proven Benefits
Peptides support firmer-looking contour along the neck and jawline.
Hyaluronic Acid restores hydration to the neck and chest.
Targeted care softens the look of crepey chest and neck skin.
How the actives work together
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
In a single-blind clinical trial, a topical caffeine and vitamin K treatment significantly reduced the look of dark circles, a 16% improvement from baseline. Every participant saw visibly brighter, smoother under-eye skin by week four.

Best for
The often-forgotten neck and decolletage — firming care.
Vitamin E supports the neck area against daily oxidative stress.
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.
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.
Palmitoyl Tetrapeptide-7
As a peptide, it sends supportive messenger-style signals that help reinforce the appearance of firmness and smoothness.
Algae Extract
Its marine minerals and sugars condition and replenish the surface, helping skin feel soft and supple.
Lactic Acid
It loosens bonds between surface cells to ease gentle exfoliation while drawing in moisture for a smoother look.
Alpha Hydroxy Acids
They dissolve the bonds holding loose surface cells, supporting gentle exfoliation and surface renewal.
Visibly firmer, more lifted and more radiant skin — age, beautifully managed.
Individual results vary based on skin condition and routine consistency.
