Age spots come from years of sun exposure. What matters most to you right now?

My skin looks dull and weathered overall - I want to resurface and renew it

Retinol (Vitamin A Topical)
Supported by controlled trials· Recognised traditional use (Evidence grade A · Traditional use recognised)Recognised traditional use
Speeds cell turnover to fade spots and smooth texture
Why this matches
Your skin looks dull or weathered overall, and retinol renews the surface - fading pigment-laden cells while smoothing texture and tone across the whole area, not just single spots.
Why try it
Its product record documents it as effective for hyperpigmentation and skin texture; it works by speeding cell turnover and boosting collagen.
Dose or use
Apply a pea-sized amount at night 2 to 3 times a week to start, building up as tolerated, and always moisturize afterward.
Time to results
Gradual - 12 weeks or more for texture and tone.
Key study
The product library documents topical retinol as effective for hyperpigmentation and skin texture; this entry is not tied here to a specific named controlled trial.
Caution
Increases sun sensitivity, so daily sunscreen is essential. Avoid during pregnancy or breastfeeding, and expect some initial dryness or flaking.
Glycolic Acid (Sugar Cane)
Supported by smaller clinical studies· Centuries of traditional use (Evidence grade B · Traditional use long-standing)Long-standing traditional staple
AHA exfoliant that resurfaces dull, weathered skin
Why this matches
For overall dull or rough texture, glycolic acid exfoliates the pigmented, weathered surface layer, helping fade spots and even the skin around them.
Why try it
A sugar-cane-derived alpha-hydroxy acid, it's a standard at-home resurfacing approach for sun-damaged skin and dark spots.
Dose or use
Use a low-strength leave-on or wash 2 to 3 nights a week to start, increasing slowly as your skin adapts.
Time to results
Texture often improves within 4 to 8 weeks.
Key study
Traditionally used as a topical exfoliant for sun-damaged skin and dark spots; documented in the library as a name-only entry and not tied here to a named controlled trial.
Caution
Makes skin more sun-sensitive, so use daily sunscreen. It can sting or redden skin; don't layer it with retinol on the same night when you're starting out.
Bakuchiol
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use
Retinol-like results with less irritation
Why this matches
Your skin reacts easily, and bakuchiol gives retinol-like brightening and renewal but is described as much gentler, so it suits sensitive skin that stings with stronger actives.
Why try it
A plant compound from Psoralea corylifolia; its product record lists hyperpigmentation and sensitive skin, and frames it as a retinol alternative without the usual irritation.
Dose or use
Apply to clean skin once or twice daily; it can be used morning or night.
Time to results
Gradual - usually 8 to 12 weeks.
Key study
The product library lists bakuchiol for hyperpigmentation and sensitive skin; this entry is not tied here to a specific named controlled trial.
Caution
Generally well tolerated, but patch-test first. Keep up daily sun protection for any spot-fading to hold.

I'd rather start gentle - my skin is sensitive or reacts easily

Niacinamide Dew Drops
Supported by smaller clinical studies· Recognised traditional use (Evidence grade B · Traditional use recognised)Recognised traditional use
Well-tolerated way to lighten spots and even tone
Why this matches
If your skin is sensitive, niacinamide is one of the best-tolerated brighteners - it lightens dark spots and evens tone while calming redness, without the sting of acids or retinoids.
Why try it
Niacinamide (vitamin B3) works differently from tyrosinase inhibitors, by limiting pigment transfer into surface skin cells, and its product record lists hyperpigmentation and redness among what it helps.
Dose or use
Apply a few drops to clean skin morning and/or night; it layers well under moisturizer and sunscreen.
Time to results
Gradual - around 8 to 12 weeks.
Key study
The product library documents niacinamide for hyperpigmentation ('lightens dark spots and evens out skin tone'); this entry is not tied here to a specific named controlled trial.
Caution
Very well tolerated; rarely, high concentrations cause mild flushing. Patch-test if your skin is very reactive.
Azelaic acid
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use
Calms overactive pigment cells; sensitive-skin friendly
Why this matches
You want to fade existing spots, and azelaic acid selectively calms overactive pigment-making cells, so it works on discrete dark spots with little effect on normal skin.
Why try it
A naturally occurring grain-derived acid; its product record lists hyperpigmentation and melasma among what it helps, and it's usually tolerable even on sensitive skin.
Dose or use
Apply the cream, gel, or foam to the affected areas once or twice daily after cleansing.
Time to results
Gradual - often 2 to 3 months.
Key study
The product library lists azelaic acid for hyperpigmentation and melasma; this entry is not tied here to a specific named controlled trial.
Caution
May cause mild tingling, itching, or dryness when you start; ease in slowly and keep up daily sun protection.
Bakuchiol
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use
Retinol-like results with less irritation
Why this matches
Your skin reacts easily, and bakuchiol gives retinol-like brightening and renewal but is described as much gentler, so it suits sensitive skin that stings with stronger actives.
Why try it
A plant compound from Psoralea corylifolia; its product record lists hyperpigmentation and sensitive skin, and frames it as a retinol alternative without the usual irritation.
Dose or use
Apply to clean skin once or twice daily; it can be used morning or night.
Time to results
Gradual - usually 8 to 12 weeks.
Key study
The product library lists bakuchiol for hyperpigmentation and sensitive skin; this entry is not tied here to a specific named controlled trial.
Caution
Generally well tolerated, but patch-test first. Keep up daily sun protection for any spot-fading to hold.

Fade the dark spots I already have

Vitamin C Topical
Limited human trials so far· Most of the research is laboratory or animal work (Evidence grade C · Traditional use recognised)Recognised traditional use
Lightens dark spots and evens skin tone
Why this matches
You want to fade the spots you already have, and topical vitamin C targets exactly that - lightening dark patches while evening out overall tone.
Why try it
Its product record documents lightening of hyperpigmentation with regular use, and as an antioxidant it also helps defend skin against further UV damage.
Dose or use
Smooth a few drops onto clean, dry skin each morning before sunscreen; start every other day if your skin is new to it.
Time to results
Gradual - usually 8 to 12 weeks of daily use.
Key study
The product library documents topical vitamin C for hyperpigmentation ('lightens dark spots and evens out skin tone'); this entry is not tied here to a specific named controlled trial.
Caution
Can sting or cause mild redness on sensitive skin; reduce frequency if that persists. Store away from light and air, as vitamin C oxidizes over time.
Alpha-Arbutin
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Gentle brightener aimed at dark spots
Why this matches
For fading existing spots, alpha-arbutin is a plant-derived brightener that works on the skin's pigment-making step, so it targets discrete dark patches.
Why try it
It's a naturally derived tyrosinase inhibitor - one of the standard non-hydroquinone brightening actives - and tends to be gentler than harsher lighteners.
Dose or use
Apply a thin layer to the spots once or twice daily, and pair it with daily sunscreen for the effect to hold.
Time to results
Typically 8 to 12 weeks with consistent use.
Key study
Traditionally used as a topical skin brightener for dark spots; documented in the library as a name-only entry and not tied here to a named controlled trial.
Caution
Generally well tolerated, but patch-test first and stop if you notice irritation or redness.
Azelaic acid
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use

Why this matches
You want to fade existing spots, and azelaic acid selectively calms overactive pigment-making cells, so it works on discrete dark spots with little effect on normal skin.
Why try it
A naturally occurring grain-derived acid; its product record lists hyperpigmentation and melasma among what it helps, and it's usually tolerable even on sensitive skin.

Caution
May cause mild tingling, itching, or dryness when you start; ease in slowly and keep up daily sun protection.
Kojic Acid (natural)
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Natural depigmenting agent for dark spots
Why this matches
To fade spots you already have, kojic acid is a classic natural brightener that interrupts pigment production in the skin.
Why try it
Derived from fungal fermentation, it's a long-used tyrosinase inhibitor for solar spots and melasma.
Dose or use
Apply to the affected areas once daily to start, working up as tolerated, and always follow with sunscreen.
Time to results
Usually 6 to 12 weeks of steady use.
Key study
Traditionally used as a topical depigmenting agent for dark spots and melasma; documented in the library as a name-only entry and not tied here to a named controlled trial.
Caution
Kojic acid is a known contact sensitizer - patch-test before use and stop if you develop itching, rash, or increasing redness, especially with prolonged use.

Protect my skin so new spots don't keep forming

Vitamin C Topical
Limited human trials so far· Most of the research is laboratory or animal work (Evidence grade C · Traditional use recognised)Recognised traditional use
Lightens dark spots and evens skin tone
Why this matches
You want to fade the spots you already have, and topical vitamin C targets exactly that - lightening dark patches while evening out overall tone.
Why try it
Its product record documents lightening of hyperpigmentation with regular use, and as an antioxidant it also helps defend skin against further UV damage.
Dose or use
Smooth a few drops onto clean, dry skin each morning before sunscreen; start every other day if your skin is new to it.
Time to results
Gradual - usually 8 to 12 weeks of daily use.
Key study
The product library documents topical vitamin C for hyperpigmentation ('lightens dark spots and evens out skin tone'); this entry is not tied here to a specific named controlled trial.
Caution
Can sting or cause mild redness on sensitive skin; reduce frequency if that persists. Store away from light and air, as vitamin C oxidizes over time.
Zinc Oxide (Topical Sunscreen)
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use
Mineral sunscreen - helps limit new spots
Why this matches
You want to protect your skin and reduce the chance of new spots, and because age spots are UV-driven, daily broad-spectrum mineral sunscreen is one of the most valuable steps - it helps reduce the chance of new spots forming and helps keep existing ones from re-darkening.
Why try it
Zinc oxide is a physical (mineral) blocker that sits on the skin and reflects UV; it's broad-spectrum and suits sensitive skin. Without daily sun protection, every fading treatment tends to underperform.
Dose or use
Apply generously to your face and any exposed skin every morning, and reapply every 2 hours when you're outdoors.
Time to results
Protective - it works from day one; the payoff over the months ahead is that new spots are less likely to form and existing ones are less likely to darken.
Key study
Broad-spectrum mineral (zinc oxide) sunscreen is a long-established, standard measure for preventing UV-driven pigmentation; documented in the library as a name-only entry and not tied here to a named trial.
Caution
A mineral formula can leave a slight white cast, and reapplication is essential for real protection. On its own it won't fade existing spots.
Polypodium leucotomos (leaf extract)
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Oral fern extract - may add sun-defense support
Why this matches
You want to reduce the chance of new spots, and this fern extract, taken by mouth, may add a layer of systemic support that complements the sunscreen you put on your skin.
Why try it
Polypodium leucotomos is traditionally used, and has been studied preliminarily, as an oral supplement that may help reduce UV-induced skin damage - a genuinely different lever from topical sunscreen, though not a substitute for it.
Dose or use
Taken as an oral capsule, typically before sun exposure; follow the product's label for timing and amount.
Time to results
Intended as ongoing support; any benefit is gradual and best judged over a sun season alongside topical protection.
Key study
Traditionally used as oral photoprotective support; documented in the library as a name-only entry and not tied here to a named controlled trial, so benefits should be considered possible rather than established.
Caution
This is an adjunct, not a sunscreen replacement - you still need daily topical sun protection. Check with your clinician if you're pregnant, breastfeeding, or on medication.

Support my skin from the inside - nutrition, supplements, or acupressure

LI11 (Quchi) - Large Intestine 11
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Acupressure point traditionally used for skin
Why this matches
For a gentle, from-the-inside addition, LI11 is the library's designated skin point - a traditional acupressure option to pair with your topical routine.
Why try it
Its record names skin conditions directly ('helps alleviate eczema, psoriasis, and other inflammatory skin conditions') and it's a classical point used for skin and inflammation.
Dose or use
Find it at the outer end of the elbow crease when the arm is bent, then press firmly with the thumb for 1 to 2 minutes, a few times a day.
Time to results
Not a spot-fading treatment; a supportive practice used on an ongoing basis.
Key study
Traditionally used acupressure point for inflammatory skin conditions per the library record; not tied here to a controlled clinical trial for age spots.
Caution
Traditional practice only - it won't lighten existing spots. Avoid firm pressure over broken or irritated skin, and skip it if you're pregnant unless cleared by a practitioner.
Vitamin C Deficiency
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Low vitamin C shows up in skin repair
Why this matches
You want to support your skin from the inside, and vitamin C is needed for collagen and skin repair, so it's worth checking your status if your skin heals slowly or feels dry.
Why try it
The library record ties vitamin C to collagen synthesis 'crucial for maintaining skin' and flags dry skin and slow wound healing as early low-level signs.
Dose or use
Aim for vitamin-C-rich foods such as citrus, peppers, and berries; consider testing or a supplement if your intake is low.
Time to results
Weeks to a couple of months to restore levels if you're genuinely low.
Key study
This is a deficiency-awareness entry, not a treatment for age spots; the library ties vitamin C to collagen and skin maintenance. No deficiency is known to cause age spots.
Caution
Correcting a deficiency won't erase existing age spots - it supports overall skin health, not spot-fading. Very high supplement doses can upset the stomach.
