Today, I want to share with you some information about SPF & PA stuff. We buy sunscreens, but are we buying the right one? I, for one, have learnt a lot from this, and I know exactly what type of sunscreen I should be buying henceforth.
Hope it will guide you too!
Information below provided by HUL India, and I'm in no way an expert on such things =)
What is SPF & PA?
What SPF is right for you?
Step 1- Choose Your Skin Type: Type III, Type IV, Type V, Type VI
I'd say I'm a Type III
Step 2- Duration of time spent in the sun: Less than 2 hours, More than 2 hours
For me it's less than 2 hours, on most days.
Step 3- Recommended SPF: According to the chart, I'd need SPF 30. If I spend more time in the sun, like at a beach (woohoo!), I'd have to use SPF 50.
A Few Myths About Sunscreen:
- Myth 1: If you're dark skinned, you don't need sunscreen ~ Sun damage doesn't depend on your complexion. True, dark skin implies presence of a higher amount of melanin in the skin - offering more natural protection as compared to a lighter complexion. However, extra melanin doesn't guard the skin from sun's UV rays that accelerate aging, causing pigmentation and sunspots. If you have dark skin, use a broad-spectrum sunscreen with an SPF of 15 or more.
- Myth 2: A sunscreen with SPF 30 is as good as a higher SPF ~ No, a higher SPF is always better. According to experts, you get 99% sunburn protection with SPF 90, as compared to 96% with SPF 30. Over a lifetime, this difference can add up to a lot less skin damage.
- Myth 3: Putting on lots of sunscreen at the start of the day will protect you all day long ~ Do this and you might end up with sun-burn. Because sunscreen wears off and must be re-applied every 3 hours or even more frequently when sweating & swimming. Also, be liberal with the amount of sunscreen you use, for optimum protection from the sun.
- Apply 1/2 teaspoon on your face and neck and 1 teaspoon on the exposed parts of your body.
- Apply 20 minutes before going out in the sun.
- If using a moisturizer, apply moisturizer first and then sunscreen.
- If using makeup, apply sunscreen as a base and then apply foundation over it, followed by other makeup.
- Re-apply every 2-3 hours, especially when out in the sun.
The above explains why PA +++ is important in a sunscreen. It protects from UVA rays, which are more harmful than UVB rays and can penetrate the skin's deepest layers, where they trigger cells called melanocytes to produce a brown spot called melanin. This pigment rises to the skin's surface and tans your skin, while your skin cells continue to get attacked by UVA rays, resulting in not only age spots, but wrinkles too.
Right now, for my body I'm using Lakmé Cucumber & Lemongrass Whitening Sunscreen SPF 30, that was launched last year, and I really like it because it's easy to blend. Now Lakmé has a new Sun Expert range to replace the previous ones. I'm going to get the Sun Expert Fairness + UV Lotion SPF 30. For face, I'm using Lotus Multi Function Sunblock SPF 70 . I just know now that I have to pick the ones with PA, since I have deep-seated hyperpigmentation.
Below is proof of how much damage the sun can do to ones skin. I first saw it on twitter, and it scared the bejesus out of me!
This man is a 69-year-old truck driver, having driven daytime hours behind the wheel for the 28 years. The left side of his face, exposed to more sunlight, exhibits more fine lines, wrinkles, loss of elasticity, sallowness, and dryness. This is due to largely cumulative DNA damage, decreased fibroblast (skin cell) production of collagen, and slowed cellular turnover. The window afforded little protection – while glass blocks nearly all UVB, it allows 62.8% of long-wavelength UVA rays through the window. And it is the UVA that is responsible for many of the visible signs of aging. Read more here [Photo courtesy: New England Journal Of Medicine]
Scary, isn't it?
Grab your SPF's now, people!
*P.S: Somebody asked me a question the other day:
Q: "....If am using a sunscreen of SPF 50 then on it foundation of SPF 15 and then powder of SPF 18...so i wanna know actually what SPF am i wearing...?"
I'd personally only take the sunscreen of SPF 50 seriously, but I'll still add them up. In this case, I would think I'm wearing upto SPF 70.
But of course that's math I'm unsure about (like any other), so if any of you know the right answer, please enlighten us! =)
