How Self Tanners Work: Understanding the Science for Safely Bronzing Skin

Understanding How Self Tanners Work

Self tanners, also known as self-tanning lotions or bronzers, offer the ability to achieve tanned skin without exposure to ultraviolet (UV) rays. These over-the-counter cosmetic products life the mortar continue to grow in popularity as awareness increases regarding skin cancer risks from excessive sun exposure or tanning beds.

The Science Behind Self Tanners

So how exactly does self tanner make your skin look sun kissed without UV light? The key lies in an active ingredient called dihydroxyacetone (DHA). When DHA interacts with dead surface skin cells, it causes a color change that closely resembles a natural tan.

Specifically, the DHA works in the uppermost layer of skin to temporarily dye protein chains in dead cells a darker color. This coloration leads to the tanned tone until the stained dead cells naturally slough off over a few days.

Types of Self Tanners

Today, consumers have more options than ever when it comes to selecting an ideal self tanner. Products exist in varying shades, formulas, applications methods and more to suit different needs and preferences.

Common types of self tanners include:

• Lotions - Applied by hand for gradual color development
• Mousses - Dispense as a foam for smooth application
• Sprays - Allow an all-over mist application
• Gels - Rub in easily for targeted color placement
• Towelettes - Wipes infused with tanner for on-the-go use

Products also come formulated to achieve light, medium or dark results. Specialty options even exist to enhance muscle tone or create a shimmer finish.

Application Tips

While exceptionally user-friendly, self tanners perform best with proper application. Useful tips include:

• Exfoliate first - Slough off dead skin cells for the best color payoff
• Moisturize dry areas - Minimize an uneven appearance
• Use latex gloves - Prevent tinted palms from giving away results
• Work in sections - Do small areas at once before product dries
• Blend thoroughly - Prevent unnatural looking streaks/spots

Carefully following usage directions for the specific product can also optimize natural-looking outcomes.

Maintenance

Unlike temporary bronzers that wash off with soap and water, self tanners absorb into the top skin layer. This allows the color to remain for several days. However, the tint inevitably fades with new skin cell turnover.

To maintain color depth, reapply self tanner as needed. How often depends varies based on factors like application technique, skin type and lifestyle.

Many users touch up self tanner every 2-4 days. Waiting too long risks an uneven appearance as the color naturally diminishes.

Safety Considerations

Reputable medical organizations like the American Academy of Dermatology consider self tanning products safe alternatives to sunlight and UV tanning methods. However, moderate precautions still merit consideration.

Choosing Products Wisely

Seeking out high-quality self tanning brands can reduce safety risks. Checking that products come from respected manufacturers and contain ingredients like:

• Dihydoxyacetone (DHA) - The active tanning agent
• Erythrulose - A keto sugar that assists with color change
• Aloe vera - A soothing plant extract
• Vitamin E - An antioxidant for skin health

...helps avoid sketchy formulations with questionable contents or purity.

Doing a Patch Test

Before slathering on self tanner all over, dermatologists strongly recommend doing a patch test. This involves:

1. Applying a small amount to a discreet spot like the arm
2. Letting it fully dry per directions
3. Waiting 24-48 hours to check for irritation or allergic reaction

Patch testing helps confirm tolerability, especially for first-time self tanning product users.

Avoiding Contact with Eyes/Mouth

Getting self tanner spray or lotion in the eyes or mouth could cause burning, stinging or other harm. Carefully avoiding mucus membranes prevents this.

Also, thoroughly washing hands after application minimizes any risks from accidentally ingesting residual traces.

Achieving a Healthy Glow

Using self tanners lets people build a bronzed goddess glow all year long without UV ray dangers. Following best practices for selecting, applying and maintaining products creates convincing, safer results.

Taking basic safety precautions also reduces the slim chances for adverse effects. With thoughtful use, self tanners offer a sun-kissed look without skin damage baggage.
