Can you fade dark spots from the inside out? Some oral formulations have shown improvements in pigmentation measurements, but the most useful routine combines daily sun protection, treatment suited to the type of dark spot, and optional oral support with relevant human evidence. Expect gradual change. A supplement trial lasting 12 weeks does not mean every spot will disappear in three months.
A more even-looking complexion starts with understanding the mark you want to change. This guide brings the steps together, including where an oral protocol such as RADIANCE can fit.
1. Identify the type of dark spot
A mark left by acne, a sun spot and melasma can all look brown, but they need different approaches. These common patterns can help you describe the concern to a dermatologist; they are not a diagnosis. [1] [2] [3]
| Pigmentation type | Typical context | Care priority |
|---|---|---|
| Post-inflammatory hyperpigmentation | Marks following acne, irritation, eczema or injury. | Control the inflammation and avoid repeated irritation. |
| Solar lentigines | Persistent, localised marks on sun-exposed skin, often called age spots. | Confirm the diagnosis before choosing a targeted treatment. |
| Melasma | Broader patches, often affecting both sides of the face. | Combine light protection with an individual treatment and maintenance plan. |
Have an unfamiliar or changing spot assessed before trying to fade it. A lesion that changes shape or colour, bleeds or looks different from your other marks deserves medical attention. Some lesions that resemble age spots require a different diagnosis.
2. Make daily light protection consistent
Choose a broad-spectrum, water-resistant sunscreen with SPF 30 or higher. Apply it before going outdoors and reapply approximately every two hours outdoors, and after swimming or sweating. Shade and a wide-brimmed hat add protection. [4]
For melasma and pigmentation-prone skin, a tinted sunscreen containing iron oxides can add protection against visible light. Look for a shade and texture you will use consistently. An SPF number alone does not describe visible-light protection.
Keep this step even when your complexion begins to look more even. Continued protection helps limit repeated darkening and supports the rest of your routine.
3. Choose topical care for your pigmentation
Depending on the diagnosis and your skin’s tolerance, options can include azelaic acid, vitamin C or a retinoid. A dermatologist may recommend prescription treatment for melasma or persistent pigmentation. Topical care has a direct role in pigment management; a supplement does not make it redundant. [1] [2]
Introduce changes gradually. Burning, persistent stinging or peeling is a reason to reassess the routine, because irritation can leave additional marks. Avoid retinoids during pregnancy; ask your clinician which treatments are suitable. [1] [8]
For confirmed sun spots, a dermatologist may discuss a peel, laser or another targeted procedure. These can work more quickly than creams, but can also cause pigment changes. The right choice depends on your skin and the lesion. [3]
4. Assess oral support by the studies behind it
The question is whether a particular formulation changed a relevant outcome in people. An antioxidant mechanism or a laboratory enzyme result cannot answer that on its own.
Defined botanical formulations
BELIGHT³™ combines grape-seed, grape-pomace and licorice extracts with vitamin C. Two randomized, double-blind, placebo-controlled trials studied it over 12 weeks: one enrolled 58 Asian adults, and the other 66 Caucasian adults. Facial pigmentation or selected dark-spot lightness measures favoured the active formulation. [5] [6]
These are encouraging, relatively small studies. Participants with melasma were excluded from the first trial, so it should not be presented as evidence of melasma treatment. The 2025 study was funded by the ingredient supplier, Activ’Inside.
Oral glutathione
A 2025 systematic review reported improvements in melanin measurements in oral glutathione studies, while highlighting mixed study quality and uncertainty about lasting effects. This supports continued investigation, without establishing reliable clearance of every kind of dark spot. It also does not establish that liposomal glutathione is superior for pigmentation. [7]
For a fuller comparison, read which supplements have human evidence for hyperpigmentation. Our vitamin C guide also separates topical evidence from oral combination studies.

Where RADIANCE fits in the routine
RADIANCE is SKINĒDIT PARIS’s oral protocol for a more even-looking, luminous complexion. Its LumiTech 5™ formulation brings together BELIGHT³™, liposomal glutathione, L-cystine, curcumin, selenium and maritime pine, with BioPerine® as a formulation partner. These choices reflect an interest in pigment biology and antioxidant pathways. [9]
The BELIGHT³™ trials explain part of that ingredient selection. They did not test finished RADIANCE, and the wider formula should not inherit their results or be assumed to outperform the studied ingredient.
The daily routine is two capsules with food, alongside photoprotection and appropriate topical care. RADIANCE is presented as a 90-day protocol; the ingredient trials lasted 12 weeks. Neither timeframe guarantees an individual result. Check suitability with a clinician if you take medication, have a medical condition, or are pregnant or breastfeeding.

How long should you give a dark-spot routine?
Use 12 weeks as a review point, not a promise of clearance. It matches the endpoint of the botanical trials discussed above. It does not mean every form of pigmentation follows the same schedule.
- Marks after inflammation: superficial marks can take months to fade after the trigger is controlled; deeper pigment may persist much longer. [1]
- Melasma: treatment often requires several months, with continued maintenance because patches may recur. [2]
- Sun spots: persistent lesions may need targeted treatment; waiting for a supplement alone may not address them. [3]
To make your own progress easier to judge:
- Start with a baseline photograph. Use the same camera, lighting and angle for later comparisons, without filters.
- Keep a brief routine record. Note new products, irritation and changes in sun exposure.
- Compare periodically. Monthly photographs are more useful than judging small daily changes in different mirrors.
- Review what changed. If you introduced a topical and a supplement together, photographs cannot isolate which caused an improvement.
If progress is disappointing, revisit the diagnosis and treatment plan with a dermatologist. Increasing the number of supplements is not automatically the next useful step.
Frequently asked questions
Can supplements fade dark spots without skincare?
Some have shown pigmentation effects in trials, but they do not replace light protection or treatment suited to your diagnosis. Consider oral support within the whole routine, rather than expecting a capsule to erase an individual lesion.
Does sunscreen help existing dark spots?
It helps limit further darkening and supports improvement from other measures. For melasma and pigmentation-prone skin, an iron-oxide tint can add visible-light protection to broad-spectrum UV protection.
Will dark spots disappear in 12 weeks?
Not necessarily. Twelve weeks is a study endpoint, not a universal clearance deadline. The type and depth of pigment, ongoing triggers and treatment all influence the timeline.
Is RADIANCE a treatment for melasma?
No. RADIANCE is a food supplement designed around complexion concerns. Melasma needs its own assessment and management plan. Read our guide to supplements and melasma for the evidence boundaries.
