Concern

Loss of firmness

Skin firmness falls as collagen and elastin decline with age and sun exposure. Topicals can modestly improve texture and firmness, while deeper laxity is a dermatologist-level treatment.

Combine with other concerns

Actives that work

Retinoids

strong evidence Typical: 0.25-1% retinol

Boost collagen production. Meta-analysis of RCTs shows tretinoin improved fine and coarse wrinkles.

Peptides

moderate evidence Typical: 3 ppm pal-KTTKS

Signal collagen production. A palmitoyl pentapeptide trial found significant wrinkle and fine line improvement.

Growth-factor serums

emerging evidence Typical: varies

Contain signaling proteins; one trial reduced photodamage. Evidence is from small, often company-sponsored studies.

Vitamin C

moderate evidence Typical: 10-20%

Needed for collagen formation and protects against UV. Photoaging scores improved in a small trial.

What to buy

Cheapest first. Start with the budget pick.

Routine

Morning

  3. Peptide moisturizer
  4. SPF 30+

Evening

  1. Cleanser
  2. Retinol (start 2 nights/week)

Cautions. Retinoids are not for pregnancy; patch test, and use sunscreen. In-office treatments are better for significant sagging.
