Supplements and practices linked to problems for people with this condition.

Black SalvepracticePossible
A 2023 case series found cancer persisted after black salve treatment in 28.8% of cases, including potentially metastatic cancers. Caustic destruction can obscure pathology, leave malignant tissue behind, and delay effective cancer care.

Red Light Therapy (Photobiomodulation)practiceUnclear
Direct irradiation of malignant skin lesions is generally avoided because of a theoretical risk of stimulating tumor growth, although red light therapy is not carcinogenic.

How to read the evidence

Evidence tier — overall strength of the evidence for the whole compound

StrongWell established — backed by strong, consistent human research.
ModerateSome genuine support, but mostly from small or lower-quality studies. Promising, not proven.
PreliminaryEarly-stage evidence — a promising hypothesis, not an established effect yet.
LimitedVery limited evidence — treat this as a hypothesis, not proof.
InsufficientNot enough good evidence to draw conclusions yet.

Certainty — how sure we can be that the effect is real

Very highVery sure — strong, consistent evidence
HighFairly sure — consistent evidence from good studies
MediumModerately sure — new studies could change this
LowNot sure — little or mixed evidence
Very lowVery unsure — almost no usable evidence

Source — where the data comes from

Meta-analysisPooled analysis of many trials — the strongest evidence
RCTRandomized controlled trial — a strong human study design
ClinicalA human clinical study
Reference knowledgeFrom general health-science or pharmacology references, not a study of this exact claim
Animal researchStudied in animals, not humans
Community reportsAggregated user reports — anecdotal signal, not evidence
TheoreticalMechanism-based reasoning, not yet tested

Study grade — quality of each underlying study (A best, D weakest)

AHigh-quality — strong, consistent human trials
BGood — solid evidence with some limitations
CModerate — limited, small, or mixed-quality studies
DWeak — preliminary, indirect, or animal-only

Confidence — how strongly the sources back a finding

A 0–100 score from study quality and agreement

Most supplement evidence is graded C–D. Read it as preliminary signal, not proof.

Full write-up

What is it

Skin Cancer is an oncology-focused health condition. This page considers it in relation to potential interventions, including Resveratrol. This section does not specify how Skin Cancer appears, what a person may notice, or how it differs from other skin conditions, so those distinctions should not be inferred here. Any medical condition warrants discussion with a clinician.

Evidence-backed options

Resveratrol is associated with anticancer findings for Skin Cancer, but the supporting evidence is limited in how directly it applies to people. The reported findings come from in vitro and in vivo evaluations, indicating activity across several stages of carcinogenesis, including initiation, promotion, and progression.

These findings describe biological activity in experimental settings rather than a demonstrated treatment effect in people with Skin Cancer. No treatment dose, duration, or time to response is specified here, so the available information cannot establish how resveratrol was taken, how quickly an effect might appear, or whether it improves clinical outcomes. The evidence is therefore best understood as preliminary rather than a basis for replacing established medical care. Anyone considering an option for Skin Cancer should discuss it with a qualified clinician.

What to avoid

Black Salve is flagged because a known or suspected malignant skin lesion requires diagnostic biopsy and definitive treatment. Its caustic destruction can obscure pathology, leave malignant tissue behind, and delay effective cancer care, making it unsuitable as a substitute for evaluation and established treatment of a suspicious lesion.

Selenium is flagged because some epidemiological studies and a secondary analysis of the NPC trial suggest that selenium supplementation may increase the risk of non-melanoma skin cancer, specifically squamous cell carcinoma, in individuals with a history of skin cancer. This potential risk warrants caution when considering Selenium in this context. Any medical condition or suspected skin lesion should be discussed with a clinician.
