The plan
Weeks 1–4
Sunscreen habit
SPF every morning, top-up outdoors; moisturiser.
In an RCT, daily sunscreen slowed skin ageing; the habit must come first.
Morning
Gentle cleanse (or water rinse)
Lukewarm water; a 5-cent-coin amount of fragrance-free, soap-free cleanser; massage 30–60 seconds with fingertips; rinse; pat dry — never rub.
Why: Removes overnight oil and sweat without stripping the barrier lipids that keep water in.
Fragrance-free moisturiser
Apply within 3 minutes of patting dry, while skin is slightly damp: a 10-cent-coin amount for face and neck, pressed in, not rubbed hard.
Why: Humectants pull water into the outer layer; occlusives and ceramides seal it in, reducing transepidermal water loss.
Daily broad-spectrum SPF 30+ (face, neck, hands)
Two-finger rule for face and neck plus the backs of the hands, every morning, rain or shine. Tinted iron-oxide formula if you have dark marks. Budget option: SPF on the face only plus shade, hat and long sleeves.
Leave on: 15 min before sun
Why: In a large RCT, daily sunscreen users showed no detectable increase in skin ageing over 4.5 years. Dark skin is better protected, but still ages and marks in the sun.
Midday sunscreen top-up (if outdoors)
Blot sweat first, then pat on a fresh layer (one finger-length), or use an SPF powder over makeup.
Why: Sunscreen breaks down with sun and sweat; most people apply too little the first time.
Evening
Evening cleanse
If you wore sunscreen or makeup, cleanse twice (first pass loosens, second cleans). 60 seconds total per pass, lukewarm water, pat dry.
Why: Sunscreen and makeup left overnight can clog pores; a thorough but gentle cleanse prepares skin for treatments.
Fragrance-free moisturiser
Apply within 3 minutes of patting dry, while skin is slightly damp: a 10-cent-coin amount for face and neck, pressed in, not rubbed hard.
Why: Humectants pull water into the outer layer; occlusives and ceramides seal it in, reducing transepidermal water loss.
Habits
Shade & hat
Wide-brim hat outdoors 10:00–16:00; seek shade; stay back from cooking fires and hot ovens where you can.
Why: Sun, visible light and heat all drive pigment, especially in melasma.
No smoking
If you smoke, ask your pharmacist or clinic about quitting support.
Why: Smoking speeds skin ageing and slows healing.
Sleep 7–9 hours
Screens off 30 minutes before bed; same bedtime daily.
Why: Sleep loss raises stress hormones that worsen acne, eczema and dull skin.
Weekly progress photo
Same place, same daylight by a window, no filter, no makeup; front, left and right.
Why: Change is slow; consistent photos show progress memory cannot.
Food
Hydration
Water with each meal and whenever thirsty; more in heat and harmattan.
Why: Supports overall health; skin hydration is mostly about the barrier, so pair water with moisturiser.
Weeks 5–12
Add a night retinoid
Retinol or adapalene at night, built up slowly; keep SPF.
Retinoids improve texture and tone over months; slow build-up avoids irritation and dark marks.
Morning
Gentle cleanse (or water rinse)
Lukewarm water; a 5-cent-coin amount of fragrance-free, soap-free cleanser; massage 30–60 seconds with fingertips; rinse; pat dry — never rub.
Why: Removes overnight oil and sweat without stripping the barrier lipids that keep water in.
Fragrance-free moisturiser
Apply within 3 minutes of patting dry, while skin is slightly damp: a 10-cent-coin amount for face and neck, pressed in, not rubbed hard.
Why: Humectants pull water into the outer layer; occlusives and ceramides seal it in, reducing transepidermal water loss.
Daily broad-spectrum SPF 30+ (face, neck, hands)
Two-finger rule for face and neck plus the backs of the hands, every morning, rain or shine. Tinted iron-oxide formula if you have dark marks. Budget option: SPF on the face only plus shade, hat and long sleeves.
Leave on: 15 min before sun
Why: In a large RCT, daily sunscreen users showed no detectable increase in skin ageing over 4.5 years. Dark skin is better protected, but still ages and marks in the sun.
Midday sunscreen top-up (if outdoors)

Why: Sunscreen breaks down with sun and sweat; most people apply too little the first time.
Evening
Evening cleanse
If you wore sunscreen or makeup, cleanse twice (first pass loosens, second cleans). 60 seconds total per pass, lukewarm water, pat dry.
Why: Sunscreen and makeup left overnight can clog pores; a thorough but gentle cleanse prepares skin for treatments.
Retinol 0.25–0.4% (or adapalene 0.1%) at night
Dry skin, pea-size amount for the face. Start twice a week, build to every other night, then nightly if comfortable; moisturiser on top. Sunscreen every morning. Not in pregnancy or breastfeeding.
Leave on: 20 min on dry skin
Why: An RCT found retinol 0.4% improved naturally aged skin; retinoids also fade uneven tone. Most trials are in lighter skin.
Fragrance-free moisturiser
Apply within 3 minutes of patting dry, while skin is slightly damp: a 10-cent-coin amount for face and neck, pressed in, not rubbed hard.
Why: Humectants pull water into the outer layer; occlusives and ceramides seal it in, reducing transepidermal water loss.
Habits
Prescription tretinoin (doctor or pharmacist)Doctor or pharmacist
If you want a stronger retinoid, ask a doctor or pharmacist about tretinoin. Not in pregnancy or breastfeeding. Your doctor or pharmacist will advise the dose and how long.
Why: A systematic review of RCTs shows tretinoin improves photoageing; it is more irritating, so start under advice to avoid dark marks.

Monthly skin check: palms, soles, nails, old scars
Look at palms, soles, between toes, nails and any old burn or scar. Photograph anything new.
Why: In Black skin, the key skin cancers appear on palms, soles and nails, or in old scars and burns.
Shade & hat
Wide-brim hat outdoors 10:00–16:00; seek shade; stay back from cooking fires and hot ovens where you can.
Why: Sun, visible light and heat all drive pigment, especially in melasma.
Weekly progress photo
Same place, same daylight by a window, no filter, no makeup; front, left and right.
Why: Change is slow; consistent photos show progress memory cannot.
Check every pack for a NAFDAC number
Before buying, look for the NAFDAC registration number and an intact seal. Buy from a registered pharmacy, not a market table or social-media seller.
Why: Counterfeit and mislabelled creams are common; some "plain" creams secretly contain steroids, mercury or strong bleaching agents.

Food
Hydration
Water with each meal and whenever thirsty; more in heat and harmattan.
Why: Supports overall health; skin hydration is mostly about the barrier, so pair water with moisturiser.
Milestones
Your weekly check-in
Ask yourself these once a week. If an answer worries you, stop and see a doctor or pharmacist.
Stop and see a doctor if
- A new or changing dark spot on a sole, palm or nail: see a doctor promptly
- A sore that will not heal, especially in an old scar or burn
- Retinoid irritation that lasts: stop and use barrier care only
- Pregnant, trying or breastfeeding: stop retinoids
In an emergency, call 112112999911911.
