SPF: The Non-Negotiable Step in Every Skincare Routine

At Indigo Clinic, we’re passionate about helping our clients protect and enhance their skin health at every stage of life. And if there’s one product we believe everyone should use daily, it’s sunscreen.

Not just for beauty—but for prevention, protection, and long-term preservation.

SPF (Sun Protection Factor) is one of the most powerful tools in the fight against premature ageing, pigmentation, and skin cancer. Yet despite overwhelming scientific support, it remains one of the most misunderstood steps in skincare.

Let’s break down the facts, debunk the myths, and help you choose the right SPF for your skin type.

What Is SPF and Why It Matters

SPF measures how well a product protects your skin from UVB rays, which cause sunburn and contribute to skin cancer. Here's what the numbers really mean:

  • SPF 15 blocks ~93% of UVB rays
  • SPF 30 blocks ~97%
  • SPF 50 blocks ~98%
  • SPF 100 blocks ~99%

But UVB is only half the story. For full protection, choose a broad-spectrum sunscreen that also shields against UVA rays, which penetrate deeper and lead to ageing, DNA damage, and hyperpigmentation.

Chemical vs. Mineral Sunscreen

There are two main types of sunscreen—both effective, but suited to different needs.

Chemical Sunscreen

Also called "organic" filters, these absorb UV rays and convert them into heat.

  • Requires 20 minutes to activate
  • Lightweight, non-greasy finish
  • Ideal for most skin types and makeup wearers

Mineral Sunscreen

Also known as "physical" SPF, made with zinc oxide or titanium dioxide.

  • Works immediately after application
  • Best for sensitive, post-treatment, or children's skin
  • May leave a white cast, depending on formulation

Hybrid SPFs are also available, combining the benefits of both.

Choosing the Right SPF Formulation

Select based on your skin type and lifestyle:

  • Creams & Lotions – Ideal for dry or mature skin
  • Gels – Lightweight, perfect for oily or acne-prone skin
  • Sprays – Easy to apply but must be used evenly
  • Sticks & Powders – Great for on-the-go touch-ups, especially over makeup

Common Myths About Sunscreen

Myth: SPF Causes Cancer

There’s no scientific evidence that SPF causes cancer. In fact, research confirms that daily sunscreen use prevents skin cancers, including melanoma. Modern formulations are designed to be safe, effective, and non-toxic when used as directed.

Myth: SPF Blocks Vitamin D

Studies show that sunscreen does not significantly block Vitamin D synthesis. Most people still get sufficient sun exposure throughout the day. If you're deficient, taking a supplement is safer than risking sun damage.
