It is best known as a natural aging process and is continuous in process which proceeds normally from your mid-20's. Anti aging's are not much effective in these due to the fact that collagen production slows down and elastin responsible for the snapping back of the skin becomes less of a spring. Dead skin cells also act sluggish with respect to the emergence of new skin. True that the aging begins from the 20s the signs might not appear for the decade and this is the major drawback when treating internal aging that it can’t be easily identified.
There are a variety of factors responsible for premature aging which are all environment inflicted. Most of which is caused by the skin. Other factors are repetitive facial expressions, gravity, sleeping position and smoking habits.
The exposure to sun makes anti aging remedies less operative. Freckles, age spots, spider veins on the face, rough and leathery skin, lose and blotchy complexion and the most fatal skin cancer and many others can be traced to the sun exposure.
