Spf myths Explained: Dermatologist-Approved Tips

Sunscreen is one of the most important skincare products, yet it is also the most misunderstood. Many people apply SPF daily and still deal with tanning, pigmentation and dull skin. This leads to confusion and the belief that “SPF doesn’t work for me.” In reality, it’s not sunscreen that fails — it’s the myths around SPF usage that cause damage.

For Indian skin, which is exposed to strong UV rays almost all year, understanding sunscreen correctly is essential. This blog breaks down the most common SPF myths and explains dermatologist-approved tips to use sunscreen the right way and actually see results.

Myth 1: “SPF Is Only Needed on Sunny Days”

This is one of the biggest misconceptions.

UV rays:

• pass through clouds

• are present during winter and monsoon

• affect skin even on cool days

Skipping sunscreen on cloudy days leads to gradual pigmentation and ageing.

Myth 2: “Higher SPF Means All-Day Protection”

SPF 50 does not mean protection lasts all day.

Sunscreen breaks down due to:

• sweat

• oil

• pollution

• touching the face

Without reapplication, protection reduces drastically.

Myth 3: “If I Stay Indoors, I Don’t Need Sunscreen”

UVA rays penetrate windows.

If you:

• sit near windows

• work in daylight

• use screens often

your skin is still exposed. Indoor sunscreen use prevents long-term damage.

Myth 4: “Applying a Small Amount of SPF Is Enough”

Most people apply less than half the required amount.

Using too little sunscreen:

• reduces protection

• allows tanning

• worsens pigmentation

Dermatologists recommend the two-finger rule for face and neck.

Myth 5: “Sunscreen Causes Acne and Oiliness”

This usually happens due to the wrong sunscreen texture.

Heavy or greasy sunscreens clog pores, especially in Indian humidity.

Dermatologists recommend gel-based, lightweight sunscreens for daily use.

Myth 6: “Makeup With SPF Is Sufficient”

Foundation or compact SPF is applied in very small amounts.

Makeup SPF:

• adds minimal protection

• cannot replace sunscreen

Proper sunscreen should always be applied before makeup.

Myth 7: “Natural Oils Can Replace Sunscreen”

Natural oils do not provide reliable UV protection.

Using them instead of sunscreen:

• increases sun damage

• worsens pigmentation

• accelerates ageing

Sunscreen is scientifically tested — home remedies are not.

Myth 8: “Sunscreen Is Only for the Face”

Neck, ears and exposed areas tan faster than the face.

Skipping these areas causes:

• uneven skin tone

• visible ageing

• stubborn pigmentation

Sunscreen should be applied wherever skin is exposed.
