What are ultraviolet rays?
Ultraviolet radiation is a segment of the broad radiation that comes from the sun towards the earth. Ultraviolet radiation is divided into UV-A, UV-B and UV-C. Visible light and infrared radiation can also damage skin.
UV-A(320-400nm) rays pass effortlessly through the ozone layer. It penetrates into the dermal layers and stimulates melanin synthesis. It also causes premature skin ageing and wrinkles. As UVA is of longer wavelength compared with UVB, it is less affected by altitude or atmospheric conditions.
UV-B(290-320nm) stimulates Vit. D. Most UVB rays are absorbed by the ozone layer. Excess UVB can cause sunburn, cataract, immune system damage etc.
UV-C(100-290nm)-these rays are the most dangerous. Fortunately, these rays are blocked by the ozone layer and cannot reach the earth.
What is SPF?
All sunscreens are labelled with a sun protection factor (SPF) number. This relates to the amount of time it takes for your skin to burn without any protection and how long it would take if you used the appropriate amount of sunscreen. An SPF 15 product filters out more than 93% of the UVB in sunlight allowing about 7% penetration. An SPF 40 filters out 97.5% of UVB rays.
What is Protection grade for UVA (PA)?
There are 3 PA grades: PA+, PA++ and PA+++ with each additional plus (+) indicating a higher protection. So, when buying a sunscreen lotion, one should note the SPF as well as the PA.
What is Noncomedogenic?
Noncomedogenic is a term applied to oils, lotions and sunscreen creams or gels that do not block pores. They are also sometimes referred to as non-occlusive. The theory behind using lotions/ creams/ gels that are noncomedogenic is that by not blocking pores they will reduce the incidence of pimples.
Tips
- Avoid direct sun exposure as much as possible during peak UV radiation hours between 10:00 a.m. and 3:00 p.m. Avoid unprotected UV exposure, seek shade.
- Wear sun protective clothing, a hat and glasses.
- Apply broad spectrum sunscreen with SPF 30 or higher with PA +++.
- Routinely check skin and report changes to your dermatologist.
- Educate yourself and others.

My Experience
The sunscreen is a light yellow coloured product that comes in a white tube with gold screw-in cap. The tube is very convenient to carry around. It is leak proof & easy to use. The texture is very smooth to work with; it spreads easily. It leaves my skin matte and feels light on the skin. It truely makes my skin hydrated, smooth and soft even without any extra moisturiser. The fragrance is gentle, soothing and refreshing aroma. I love this product for my oily skin. Its travel friendly. It is a little expensive but worth it. It does mention complete ingredients. Undoubtedly this is one of the best sunscreens for oily-acne prone skin. Also I never forget to reapply the sunscreen. I used to apply morning and afternoon.
