Picking up the correct sunscreen is crucial in getting glass-like skin. There are tons of options available in the market but selecting the right one based on your skin type and concern makes a huge impact. Both physical and chemical sunscreens aim to protect the skin and offer complete sun protection but the difference arises when we compare them in terms of their mechanism, ingredients, and their impact of effect on the skin. In this blog we will delve into the details of physical and chemical sunscreens and and on top of that, we will also delve into which could be an ideal sunscreen for your skin type.

Physical Sunscreens and Their Impact

The other class of sunscreens are called physical sunscreens, and they are sometimes referred to as mineral sunscreens. Active minerals for the physical sunscreens include zinc oxide and titanium dioxide. These minerals are the key, as they are adept at their work: they don't absorb into your skin, and create a physical barrier sitting on top of your skin that optimal blocks out the sun's UVA and UVB rays. When you apply a cosmetic cream, gel, or spray to block UV radiation, a thin layer of the outer layer of the skin serves as a sophisticated sunscreen before the UV radiation reaches the skin.

Key ingredients used in Physical Sunscreens

Key ingredients used in Physical Sunscreens
  1. Zinc oxide: It gives major protection to the skin, providing broad-spectrum protection for both UVA and UVB rays. These are suitable for sensitive skin also.
  1. Titanium Dioxide: It is an inert earth mineral that protects skin from UVA and UVB radiation and is considered no risk of skin sensitivity. Because it’s gentle, titanium dioxide is a great sunscreen active for sensitive, redness-prone skin. It’s great for use around the eyes, as it is highly unlikely to cause any irritation to the skin.

Physical Sunscreens and Their Impact

Advantages of Physical Sunscreens

  • Ideal for Sensitive Skin: Less absorbed by skin so chances of getting irritation or allergy is very minimal. 
  • Immediate Protection: Physical sunscreens show their work immediately the moment they are applied to the skin.
  • Perfect for Daily Use: These are non-comedogenic i.e., they don’t clog pores, so they become a great solution for daily use
  • Reef-Safe: It is environment-friendly as no harm has been caused by the ingredients of physical sunscreen to marine life.
  • Long Lasting: Offers even coverage and long-lasting protection from the sun. 

Chemical Sunscreens and Their Impact

Chemical sunscreens work differently from mineral sunscreens. Instead of blocking UV rays, they absorb them and convert the rays into heat, which is then released from the skin. These sunscreens typically contain ingredients like oxybenzone, avobenzone, octisalate, and octocrylene.

Product Recommendations

  2. Oxybenzone: Absorbs UVB and some UVA rays but it has a trait of causing skin irritation.

Comparison Between Physical and Chemical Sunscreens

  • Physical sunscreens generally leave a white cast on the skin and it may look bad on people with dark skin tones.
  • Physical/mineral sunscreens can give a feel of heaviness or greasy which may be uncomfortable.
  • As the sunscreen sits on the skin it can be easily rubbed off by water or sweat. 
  • Some ingredients of chemical sunscreen can cause skin irritation which may be accompanied by redness, itching, etc.
  • Many of the sunscreens are not environmentally friendly and they mainly cause harm to the reef life.

Which Sunscreen to Choose?

Ideal Sunscreen for Daily Usage: For daily dosage, the best sunscreen would be a chemical one as it easily blends with the skin without leaving and white patch or mark moreover these are lightweight and easy to apply.

Reef-Safe Sunscreen: Choosing an environmentally friendly sunscreen is also quite important to preserve our coral lives especially. So choosing physical sunscreen would be a hit in this case as it is eco-friendly and reef-safe as well.

Shadow SPF 50+ Cream  is a lightweight cream-based sunscreen that provides excellent UV rays coverage for a longer duration. This photostable sunscreen is ideal for all weathers and suits all skin types including dry and sensitive skin.

Conclusion: Choosing between physical and chemical sunscreen entirely depends on your skin type, lifestyle, and other factors. For people with sensitive skin and good protection, it is advisable to go with physical sunscreens. However, if you prefer lightweight and water-resistant sunscreen then we would recommend you a chemical one. 

No matter what type of sunscreen you choose(mineral/chemical) apply it regularly to keep your skin safe from UV rays.
