Concern

Neck & chest

Neck and chest skin is thinner and gets sun-damaged and crepey like the face. Most evidence is from facial studies, so treat it as extrapolated; see a dermatologist for sun spots or changing moles.

Combine with other concerns

Actives that work

Sunscreen

strong evidence Typical: SPF 30-50

Daily sunscreen reduced skin aging in a 4.5-year trial, and the neck and chest are often neglected.

Retinoids

moderate evidence Typical: 0.25-0.5% retinol

Trials on face and forearm skin show collagen and wrinkle improvement. Neck and chest are more sensitive, so start slowly.

Vitamin C

moderate evidence Typical: 10-15%

Antioxidant that supports collagen and brightness. Trials were on the face.

Peptides and growth factors

emerging evidence Typical: varies

May signal collagen production. Evidence is early and from facial studies.

What to buy

Cheapest first. Start with the budget pick.

Routine

Morning

  1. Apply sunscreen to neck and chest
  2. Vitamin C

Evening

  1. Retinol 2-3 nights/week
  2. Moisturizer

Extend your face routine down to the chest; start retinol at half the frequency.

Cautions. Neck and chest skin is more sensitive than the face. Retinoids are unsuitable in pregnancy without advice, and any changing spot needs a dermatologist.
