Sunscreen and Skin Protection Therapy

Sunscreens are the most important product that should be used everyday. Not only is it anti-aging, it will also reduce your risk of skin cancer. Various bases of sunscreen are available for various skin types. These include Non-comodegenic type for acne patients , mositurising base for dry skin and very high protection for those with a history of skin cancer or those that work outdoors.

Excessive UV radiation causes skin damage. UVB radiation causes “sunburn” and is related to causation of skin cancer. UVA radiation is more silent – it does not cause the typical redness caused by UVB radiation. UVA radiation can penetrate window glass. UVA radiation penetrates deeper into the skin contributing to aging effects on the skin, including pigmentation wrinkles and breakdown of elastin.

SPF of Sunscreens
SPF : Sun Protection Factor
It is an international measure of ability of sunscreens to filter UV Radiation.

There are some limitations of using SPF as a guideline. These include:
– variation in thickness of sunscreen applied
– may not protect against UVA Radiation
– variation in effectiveness depending on humidity, water exposure.

Types of Sunscreens
There are two types of sunscreens – Physical sunscreens and Chemical sunscreens.

Chemical Sunscreens (like para-aminobenzoic acid, benzophenones, and cinnamates) absorb UV radiation and convert it to a harmless form of energy. Broad spectrum Chemical sunscreens are effective against UVB and UVA radiation.

Physical Sunscreens (Titanium dioxide, zinc oxide) lie on top of the skin and create a physical barrier to UV Radiation. Advantages of physical sunscreens are that they are less likely to cause allergic reactions than chemical sunscreens, provide longer duration of action and they reflect UV radiation.

Examples of Physical sunscreens are:
– Cosmedix Pure Protection
– Cosmedix Reflect

Sunscreen Makeup

We cannot rely on sunscreens in makeup. Many factors are needed for effectiveness of sunscreens. It is best to apply sunscreen that is known to be effective under the foundation.

If you require assistance with your skin condition, we can help.

Every patient presenting with a skin condition is reviewed by a doctor and an appropriate treatment and on-going skin care plan is developed to suit your specific case.

Frequently Asked Questions

What is the Sunscreen and Skin Protection service at Nitai Clinic?

Sunscreen and Skin Protection refers to the use of medical-grade sunscreens and personalised sun-protection strategies to protect skin from harmful UV rays, prevent premature aging, and reduce the risk of skin cancer. Our clinic offers tailored sunscreen recommendations for different skin types and lifestyles, including oil-free options for acne and high-protection formulas for outdoor workers or post-skin-cancer patients.

Why is sunscreen so important?

Sunscreen is essential for daily skincare. It helps prevent sunburn, reduces premature aging (like wrinkles and pigmentation), and significantly lowers your risk of skin cancer. This is true even on cloudy days or indoors, as UVA rays can penetrate window glass.

What’s the difference between UVA and UVB rays?

UVB causes sunburn and is linked to skin cancer.
UVA penetrates deeper, contributing to aging, pigmentation, and elastin breakdown. Both are harmful without protection.

What does SPF mean?

SPF stands for Sun Protection Factor. It’s a measure of how well sunscreen filters UV radiation and helps you avoid sunburn. Higher SPF means more protection — for example, SPF 30 blocks about 97% of UVB rays.

What are the types of sunscreens available?

Physical (Mineral) Sunscreens

Contain zinc oxide and/or titanium dioxide.
It sits on top of the skin and reflects UV rays.
Gentler on sensitive skin.

Chemical Sunscreens

Absorb UV rays and convert them to harmless energy.
Often lighter, invisible finish.

Both can be effective when applied correctly.

How should I choose sunscreen for my skin type?

Acne-prone skin: Non-comedogenic (won’t clog pores) sunscreen.
Dry skin: Moisturising formulas.
History of skin cancer or outdoor work: High-protection broad spectrum sunscreens.

Nitai can help you choose the right base type for your skin needs.

Do makeup products with SPF replace sunscreen?

Not reliably. Many makeup products do contain SPF, but they often don’t provide enough coverage to match a dedicated sunscreen’s protection. It’s best to use a proper sunscreen underneath makeup.

How often should I apply sunscreen?

Apply sunscreen every day — even if it’s cloudy — and reapply every 2 hours if you are outdoors, sweating or swimming.

Is sunscreen only for summer?

No. UV radiation is present year-round. Even in winter or on cloudy days, UV rays can damage skin and contribute to aging.

Can sunscreen protect against skin cancer?

Yes, when applied properly with other protective measures, sunscreen reduces the risk of sunburn and skin cancer.

Can sunscreen prevent signs of aging?

Yes, sunscreens help prevent deep wrinkles, loss of elasticity, and pigmentation changes by blocking UVA rays.

Are mineral sunscreens better for sensitive skin?

Dermatologists often recommend physical (mineral) sunscreens with zinc oxide or titanium dioxide for sensitive skin because they’re less likely to cause irritation.

Can I get sunscreen products at Nitai Clinic?

Yes. Nitai Clinic stocks medical-grade and dermatologist-recommended products suitable for different skin types as part of your personalised skincare plan.

How can I book a consultation or get advice?

You can ask a question, request a callback, or book an appointment directly via our website or contact Nitai Clinic in Melbourne for expert guidance from our medical team.

Should children use a different sunscreen than adults?

Yes, for babies and children, mineral sunscreens with a gentle, hypoallergenic formulation are usually recommended.
