Sunscreen (also commonly known as sun screen, sunblock, suntan lotion, sunburn cream, sun cream or block out) is a lotion, spray, gel or other topical product that absorbs or reflects some of
the sun's ultraviolet (UV) radiation and thus helps protect
against sunburn.
Early civilizations used a variety of plant products to help protect the skin from sun damage. For example, ancient Greeks used olive oil for this purpose, and ancient Egyptians used extracts of rice, jasmine, and lupine plants whose products are still used in skin care today. Zinc oxide paste has also been popular for skin protection for thousands of years
The best protection is achieved by dividing the
SPF number in half and reapplying that many minutes after sun exposure begins.
For example, if the SPF is 30, sunscreen should be reapplied once after 15
minutes of exposure. Further reapplication is only necessary after activities
such as swimming, sweating, or rubbing/wiping.
Sunblock typically refers to opaque sunscreen
that is effective at blocking both UVA and UVB rays and uses a heavy carrier
oil to resist being washed off. Titanium
dioxide and zinc
oxide are two of the important
ingredients in sunblock
Everyone should use sunscreen that offers the
following:
1) Broad-spectrum protection (protects against UVA and
UVB rays)
2) Sun Protection Factor (SPF) 30 or higher
3) Water resistance
Sunlight consists of two types of harmful rays that
reach the earth — UVA rays and UVB rays. Overexposure to either can lead to
skin cancer. In addition to causing skin cancer, here’s what each of these rays
do:
UVA rays (or ageing rays) can prematurely age your
skin, causing wrinkles and age spots, and can pass through window glass.
UVB rays (or burning rays) are the primary cause of
sunburn and are blocked by window glass.
Tip/Fact: All sunscreens retain their original
strength for at least three years. Some sunscreens include an expiration date.
If the expiration date has passed, throw out the sunscreen. If you buy a
sunscreen that does not have an expiration date, write the date you bought the
sunscreen on the bottle. That way, you’ll know when to throw it out. You also
can look for visible signs that the sunscreen may no longer be good. Any
obvious changes in the colour or consistency of the product mean it’s time to
purchase a new bottle.
Neutrogena Ultra Sheer Dry Touch Sunblock SPF 50+ PA+++ with
Helioplex is a breakthrough sun protection, Stabilized with Helioplex, it provides superior
balanced broad-spectrum protection against skin-ageing, UVA and burning UVB rays, and combines it with Dry Touch
technology for an ultra-light, non shiny finish. This lightweight sun block has
a light fresh scent and is gentle enough for even sensitive skin.
It
comes in a sturdy tube with a screw top. It has a tiny nozzle which dispenses
the adequate amount of the product.
The product is milky white in colour with a
thick, creamy texture. Apparently, the consistency may seem to be too heavy for
the skin as most of the similar products are found to be runny. But it is actually
absorbed by the skin after a little massage and doesn’t feel heavy at all.
It suits my combination skin very well and I was quite surprised to see how
well it moisturises my face. There is a very light floral fragrance, which
fades away within 15 to 30 minutes of application.
It definitely gives a clean feel without a shiny
look. In fact, I like the fact that it doesn’t leave a whitish cast like most
other sun blocks available in the market. But you may not get that dry-touch
and perfect matte finish. Rather, it offers a dewy appearance with clean,
non-shiny finish and I totally love it.
