Skincare in Your 40s: What Changes and the Routine That Keeps Up

In your 40s, ageing shows faster. Lines that were faint become set, dark spots get darker, and perimenopause can make skin drier, more sensitive or spotty in ways it has not been since your teens. The routine needs to treat as well as prevent.

What changes in your 40s

  • Static lines: forehead lines, crow's feet and smile lines stay visible even when your face is relaxed.
  • More dark spots and uneven tone from accumulated sun exposure.
  • Drier skin as oil production falls.
  • Early loss of firmness along the jaw and cheeks as collagen and fat pads thin.
  • Perimenopause: hormone shifts can bring dryness, sensitivity and breakouts.

A routine for your 40s

Morning: gentle cream cleanser, vitamin C serum, a richer moisturiser, sunscreen SPF 30 to 50.

Night: cleanser, a retinoid most nights, then a moisturiser with ceramides or peptides.

Weekly: a gentle acid exfoliant once or twice a week if your skin tolerates it.

The upgrades that matter most

  • Prescription tretinoin: stronger than retinol and the best-studied option for wrinkles. Ask a doctor.
  • Tranexamic acid or azelaic acid for dark spots and melasma.
  • Peptides: supportive ingredients in moisturisers and serums, with modest evidence.
  • Barrier care: ceramides, glycerin and squalane, especially if retinoids make you dry.
BEYOND SKINCARE

In-office treatments such as neuromodulator injections, fillers, lasers and microneedling become more common in your 40s. They can complement skincare but do not replace sunscreen and a retinoid.

Men in their 40s

The same routine works. Men's skin is thicker and oilier, so a lighter moisturiser may be enough, but sunscreen and a retinoid matter just as much. Shaving counts as light exfoliation, so go easy on acids.

TRACK IT, DON'T GUESS

Rosee scans your face on your iPhone and tracks texture, tone, hydration, glow, redness and dark circles from scan to scan, so you can see whether a routine is actually working instead of guessing from the mirror. The photo never leaves your phone. After seven scans it also estimates a Skin Vitality Age, rounded to whole years and never from a single selfie. Every feature is open for your first week, then it is a monthly or yearly subscription.

Frequently asked questions

What is the best skincare routine for your 40s?

Vitamin C, a rich moisturiser and SPF 30–50 in the morning, and a retinoid with a ceramide or peptide moisturiser at night. Tretinoin is worth discussing with a doctor.

How does skin change in your 40s?

Lines become set, dark spots increase, skin gets drier and slightly less firm, and perimenopause can add sensitivity and breakouts.

Is retinol enough in your 40s?

Retinol helps, but prescription tretinoin is stronger and better studied for wrinkles. Many people in their 40s switch once their skin tolerates retinol.
