Sunscreen Regulation in South Africa: SPF Claims, Testing, and Labelling Requirements

Sunscreen products occupy an unusual regulatory space in South Africa. Depending on the claims made and the active ingredients used, a sunscreen may fall under cosmetic legislation or be classified as a medicine requiring registration with the South African Health Products Regulatory Authority (SAHPRA). Getting this classification wrong has real consequences - from product seizures and forced label changes to criminal liability under the Medicines and Related Substances Act (Act 101 of 1965). Understanding where your product sits, and what you can and cannot say about it, is essential before it reaches a South African shelf.

Cosmetic or Medicine? The Classification Question

In South Africa, cosmetics are regulated under the Foodstuffs, Cosmetics and Disinfectants Act (Act 54 of 1972), while medicines fall under Act 101 of 1965. The distinction for sunscreens hinges primarily on the claims made rather than the formulation itself.

A sunscreen marketed purely for UV protection - shielding the skin from sunburn - is generally treated as a cosmetic. However, the moment a manufacturer claims that a product prevents skin cancer, treats a dermatological condition, or provides a therapeutic benefit, the product crosses into medicine territory and must be registered with SAHPRA before it can be sold. SAHPRA has historically taken a firm stance: therapeutic claims trigger medicine classification regardless of the formulation's simplicity.

This means two nearly identical zinc oxide sunscreens can sit in different regulatory categories depending solely on their label copy. Regulatory affairs teams must scrutinise every word on the packaging, promotional material, and even social media posts to avoid inadvertent reclassification.

SPF Testing Standards Accepted in South Africa

South Africa does not maintain its own unique SPF testing methodology. Instead, SAHPRA and the relevant cosmetic regulations recognise internationally established standards. The two primary frameworks accepted are the ISO 24444 standard for in vivo SPF determination and the Colipa (now Cosmetics Europe) SPF test method, which ISO 24444 largely incorporated.

For broad-spectrum (UVA) protection claims, ISO 24443 provides the accepted in vitro method for measuring UVA protection. Products claiming broad-spectrum protection must demonstrate a UVA protection factor (UVA-PF) of at least one-third of the labelled SPF value, aligning with the European Commission's 2006 recommendation.

Testing must be conducted by laboratories with appropriate accreditation and documented quality management systems. SAHPRA expects that any SPF value declared on the label is substantiated by test data that is available for inspection. Self-declared SPF values without supporting test reports are a compliance red flag and one of the fastest routes to regulatory action.

Labelling Requirements and Permitted Claims

South African sunscreen labelling must comply with the regulations under Act 54 of 1972 for cosmetics, or with SAHPRA's labelling guidelines if the product is registered as a medicine. Several requirements apply regardless of classification.

Mandatory Label Elements

The label must include the SPF value expressed as a numeral (e.g. SPF 30, SPF 50), the product's full ingredient list using INCI nomenclature, appropriate directions for use including reapplication guidance, batch number, expiry date, and the name and address of the manufacturer or importer. Where broad-spectrum protection is claimed, this must be clearly stated.

SPF values on labels should follow the standardised categories: Low (SPF 6–10), Medium (SPF 15–25), High (SPF 30–50), and Very High (SPF 50+). Claiming exact SPF values above 50 (e.g. "SPF 100") is considered misleading under South African and most international frameworks, as the marginal increase in protection does not justify consumer perception of dramatically superior performance.

Prohibited and Risky Claims

Claims of "total sunblock," "100% protection," or "all-day protection" are prohibited. No sunscreen provides complete UV protection, and suggesting otherwise is misleading. Likewise, the term "sunblock" itself has fallen out of regulatory favour - "sunscreen" is the accepted descriptor.

Water resistance claims must be substantiated through standardised testing (ISO 16217). A product cannot simply state "waterproof" - it must specify the duration of water resistance (typically 40 or 80 minutes) based on test data.

Common Marketing Pitfalls

The most frequent compliance failures Avidara encounters during document reviews involve therapeutic creep in marketing copy - phrases like "prevents premature ageing" or "protects against skin cancer" that push a cosmetic product into unregistered medicine territory. Other common issues include unsupported SPF claims carried over from international parent labels without local test data, missing reapplication instructions, and ingredient lists that do not match the notified formulation.

Each of these issues is preventable with a disciplined review process applied before artwork approval.

Staying Compliant

Sunscreen regulation may seem straightforward until a single claim triggers reclassification or a missing test report halts a product launch. Avidara's Document Review service systematically evaluates SPF claims, label copy, and supporting test documentation against South African regulatory requirements - catching the issues that delay market entry or attract enforcement attention. If your sunscreen labels or marketing materials need a compliance check before they go to print, book a review.
