Not sure if it'll be permanent but Sun Block will help the cause. Here are some tips:
When you are using sunscreens you're supposed to use at LEAST one ounce of sunscreen should be used to cover the entire body. Most labels will say, that their sunscreen is waterproof but no sunscreen is entirely waterproof. Reapply ever 2 hours no matter what the labels say and don't wipe the sunscreen off.
Another Important Factor
Another problem with sunscreens is that they advertise ?broad-spectrum? coverage, leading parents to believe they are protecting children from both UVA (the rays associated with skin discoloration and sagging) and UVB (rays associated with burning and skin cancer).
However the SPF number only applies to UVB rays. There are UVA ratings in other countries but currently in the U.S. there are no standard measures of UVA protection.
Dermatologists say that, barring label reform, the only way to ensure adequate full spectrum protection is to be a careful label reader. There are only a few ingredients that work well to block or absorb UVA rays. Make sure your sunscreen has an SPF 30 to block UVB rays and also contains at least one of these ingredients to block UVA: zinc oxide, titanium dioxide or avobenzone (parsol 1789).
The sun is brightest during the hours of, 10 a.m. to 3 p.m.
Also, you can get more sun protection for your face and the back of your neck by wearing a really big sun hat. 6-8 inches.
A sunscreen would have to be a permanent application for the results to be permanent. There are no permanent skin care applications. Your skin cells are born, live for about 30 days & die. They are replaced by new cells. Nothing can treat those new cells before they have been born. And most products will not treat those skin cells until they are about 20 days old.
the trick is to exfoliate as deep down as possible. there are chemical peels like phenol that really do deep through several layers of skin. they usually result in permanent skin lightening but they are not ment to be used on the entire body. but with weaker, safer acids we can peel and thin the skin so that the active lighteners can get deep down and do their thing. some lightener also as a semi perminant toxic effect on the melenocites so although they are not dead they are severely hampered in their production of skin pigments. the only other problems afer a successful lightening is maintaining. you have to keep up the peeling but at the same time reverse the thining you caused.lol so we have a huge problem. our best sunscreen is our skin so when you mess that up nothing is going to do much to replace the damage.
