Understanding Sunscreen: Your Dual Defence System
Sunscreen shields your skin from harmful ultraviolet (UV) rays: UVA and UVB:

UVA rays: Penetrate the skin's dermis, causing premature ageing (wrinkles, elasticity loss, hyperpigmentation).
UVB rays: Primarily responsible for sunburn, damaging the epidermis and increasing skin cancer risk.

Sunscreens employ two mechanisms:

Absorption: Ingredients like oxybenzone and avobenzone absorb UV rays, converting them to heat released from the skin.
Reflection: Ingredients like zinc oxide and titanium dioxide physically block and reflect UV rays.

Benefits of Consistent Sunscreen Use
Sunscreen offers numerous advantages:

Sunburn Prevention: Sunburns damage skin cells and increase the risk of future skin cancer. Sunscreen is the most effective preventive measure.
Anti-Ageing: Chronic sun exposure contributes to wrinkles and fine lines. Daily sunscreen use slows these signs, preserving youthful skin.
Skin Cancer Protection: Sunscreen significantly reduces melanoma and other skin cancer risks.
Even Skin Tone: Sun exposure can cause uneven pigmentation. Sunscreen promotes a more uniform complexion.
Overall Skin Health: Shielding skin from UV damage allows for optimal cell turnover and a natural glow.

Recommended Sunscreen Protocol
Our cosmetic medicine doctors recommend the following:

Broad-Spectrum SPF 50+: Ensure protection against both UVA and UVB rays. SPF 30 is good, while SPF 50+ offers higher protection for extended exposure or fair skin.
Generous and Frequent Application: Use about one ounce (shot glass) for the face and body. Reapply every two hours or more often if swimming or sweating.
Remember: Ears, lips, neck, feet, and hands often get overlooked.
Shade and Protective Clothing: Seek shade during peak hours (10 am - 4 pm) and wear hats, long sleeves, and sunglasses.
Sunscreen and Your Skin Type: Consult a Professional

Sunscreen purchased from an Australian retailer have to legally meet stringent requirements to ensure efficacy and safety. Don’t get too bogged down into what ingredients are the best. It’s best to find a formulation that you like as this will ensure compliance.
Sunscreens come in various formulations (lotions, sprays, gels, and mineral-based). Consult a BBD doctor for personalised advice:

Sensitive Skin: Fragrance-free, mineral-based options may be less irritating.
Oily Skin: Oil-free, non-comedogenic sunscreens won't clog pores.
Dry Skin: Lotions or creams provide added hydration.
