The choice between a spray tan and a sunbed comes down to a few key factors: safety, longevity, cost, and the look you’re after. Here’s an honest comparison of both.
Spray Tans
A professional spray tan uses DHA (dihydroxyacetone), a colourless sugar that reacts with amino acids in the skin’s surface layer to produce a temporary brown colour. It doesn’t involve UV radiation.
- Safety: No UV exposure — no increased skin cancer risk. DHA is considered safe by dermatologists for topical use.
- Results: A good professional spray tan looks natural and even. A bad one can streak or turn orange — the formulation and application technique matter.
- Duration: Typically lasts 7–10 days before fading. Preparation (exfoliating, moisturising) extends results.
- Aftercare: Avoid water and sweating for 8–12 hours after application. Pat dry (no rubbing) when showering.
Sunbeds
Sunbeds emit UV radiation (primarily UVA) that triggers melanin production in the skin — the same process as natural sun tanning. The tan is real melanin pigment, not a surface colour.
- Safety: UV exposure carries genuine health risks including increased risk of skin cancer and premature ageing. The WHO classifies UV tanning devices as carcinogenic.
- Results: A genuine, deeper-looking tan. Better for very fair skin that doesn’t respond well to DHA spray tans.
- Duration: Lasts 1–2 weeks depending on skin type and sun exposure.
- Regulation: UK sunbed salons must operate within UV emission limits and age-restrict access to over 18s.
The Verdict
From a safety perspective, spray tans are the clear winner. From a result perspective, personal preference plays a role — some people love the depth of a sunbed tan, while others prefer the control and consistency of a professional spray. Many people use both: spray tan for events or holidays, and the occasional sunbed session for maintenance.
