Are You Choosing Radiant Defense Over White Casting?

What is White Casting? 

White casting refers to a visible white or grayish residue left on the skin after applying sunscreen. It's more common with mineral sunscreens that contain zinc oxide or titanium dioxide.    

Let's first understand why sunscreen leaves a white cast:   

Minerals: These minerals act as physical blockers, sitting on top of your skin to deflect UV rays. Because they're white pigments, they can leave a noticeable cast, especially on deeper skin tones. 

Formulation matters: Thicker sunscreen formulas or those with high concentrations of minerals are more likely to cause white cast.  

Causes of White Casting Due to Zinc Oxide & Titanium Dioxide: 

The key ingredients of almost every sunscreen are Zinc Oxide or titanium dioxide which act as UV blockers. In their natural form, they are white in color, therefore, it is possible to make them transparent also they are good reflectors and scatter photons once light strikes them. 

These white particles don't get absorbed and don't break down at the same time & protect our skin from radiance.  

The UV Radiants strike back before reaching out to the skin because of some good reflecting properties of zinc oxide and titanium dioxide which makes them suitable and key ingredients for a sunscreen. Though Zinc Oxide and titanium dioxide offer all these benefits, they also offer some disadvantages. 

The non-absorbing nature of zinc oxide and titanium dioxide is the reason why white casting occurs because these minute white particles of zinc oxide and titanium dioxide gather over the skin surface and give a white appearance which may be more noticeable on darker skin.  

Now let's learn about the factors that lead to greasiness in the sunscreen:    

Most sunscreens contain oil-based ingredients for water resistance and long-lasting effects. Mostly, softening agents, thickening agents, and wax are used in sunscreens.  One such most-used component is Acrylate. Its chemical composition not only helps to thicken the sunscreen consistency but also makes it water resistant. It is safe to use on the skin if used in lower concentrations. 

There are two main factors responsible for a greasy sunscreen feeling:

Ingredients: Sunscreens often contain oils to help them spread easily on the skin and make them water-resistant. These oils can leave a greasy residue on the skin, especially if used in high concentrations. Some sunscreens also contain thickening agents and waxes to create a specific texture in the sunscreen, too much of them can make the sunscreen feel heavy and greasy.

Formulation: Sometimes the way a sunscreen is formulated can impact how greasy it feels. If the sunscreen isn't well-formulated, the ingredients may not blend perfectly, leading to a greasy feel. If the active ingredients (UV filters) don't absorb well into the skin, they can leave a greasy residue on the surface. 

But is there any solution for white casting and greasiness? Yes, there are a few tips that one should follow to avoid white casting & greasiness: 

For White Cast: 

Pick your sunscreen wisely: Use mineral sunscreens labeled as "lightweight" with micronized zinc oxide or titanium dioxide. These particles are smaller and can easily blend into the skin.

Sunscreen Selection: If white cast is a major concern, try sunscreen which absorbs into the skin and typically doesn't leave a residue. 

Application technique: Apply a thin layer of sunscreen and gently mix it into your skin instead of rubbing. This allows for better absorption and reduces the risk of white cast. 

For Greasiness: 

Look for the right ingredients: Choose sunscreens labeled as "oil-free" or "non-comedogenic to avoid pore blockage. 

Lightweight formulas: Go for lightweight, water-based, or gel sunscreens. These are less greasy than thicker creams or lotions. 

Moisturization: Use sunscreen which contains ingredients such as Hyaluronic acid to keep your skin moisturized & regenerate its natural skin barrier. 

Does your sunscreen contain hyaluronic acid? 

Hyaluronic acid is noncomedogenic (i.e. it does not block pores)  in nature and is naturally present in the human body to maintain moisture levels. It has good water-retaining properties which makes it a key ingredient in products for skin hydration. Its hydrating nature helps it to reduce fine lines and gives you plumpy skin.  The presence of Fenugreek seeds helps to block melanin production and protects against hyperpigmentation.
