Human skin, like the other organs, undergoes chronological ageing. Skin ageing is influenced by the environment eg: sun exposure and life style factors like cigarette smoking, alcohol consumption, low body mass index and menopausal status. Atmospheric pollution and psychological stress are among other factors.
Ageing of the skin can be intrinsic and extrinsic. Intrinsic ageing is a naturally occurring process due to slow, but progressive and irreversible tissue degeneration. Genetic mutations and decreased levels of several hormones and cellular ageing contribute to this. Extrinsic ageing (photoageing) occurs due to UV and infrared radiation and physical factors(cold/ wind) Chronic UV exposure is the most potent environmental factor for ageing. Extrinsic ageing amplifies the changes associated with intrinsic skin ageing. Ageing affects the skin function and appearance. This leads to a low self esteem and poor social well being.
When does our skin start to age?
Ageing of the skin is different in each individual case. However, in our mid 20’s the skin’s ability to retain water starts to decrease. Most serious signs of ageing starts in 30’s and worsens gradually over the decades.
What are the signs of ageing?
Dryness of the skin, fine lines and wrinkles, sagging, prominent blood vesssels(telangiectasia)
blotchy pigmentation, freckles, lentigenes, harmless growths like skin tags, seborrhoeic keratoses
Care of ageing skin

Protection of the face from the sun is always important, and particularly in summer. Avoid outdoor activities during the middle of the day.
Do not smoke. Smoking increases facial lines and wrinkles, delays skin healing and is also bad for you. Exercise is good for the skin as well as for your general health.
Sunscreens should be applied daily on the face, more often when outdoors. Cover up when outside – sunscreens may protect against UVB but they are not effective against longer wavelengths.
Moisturisers can be used to smoothen the skin if it is dry and flaky.
Take plenty of exercise – active people appear younger. Eat a healthy diet with plenty of fruit and vegetables to provide natural antioxidants.
Consider treatments that rejuvenate aged skin. Consult a dermatologist for expert advice.
Alpha-hydroxy acids, vitamin-C, lipoic acid or retinoid creams applied regularly in the long term may reduce the number of fine wrinkles and fade blotchy pigmentation. In postmenopausal women a cream containing progesterone may improve skin elasticity and firmness.
Collagen, hyaluronic acid, polytetrafluoroethylene implants (dermal fillers) and fat grafts can disguise facial expression lines.They are given as injections.
Botulinum toxin injections are used to reduce frowning/look and lessen deep furrows near the eyes ,on the forehead and neck lines.
Resurfacing procedures such as dermabrasion, chemical peels, fractional laser treatment and laser resurfacing remove the top layer of damaged skin, which is replaced by new healthy cells.Pulsed dye laser helps to reduce the wrinkles around the eyes .
Vascular laser treatment can reduce unsightly facial veins and angiomas.
Thread veins on the legs can be treated by injections (sclerotherapy).
Radio frequency device(Thermage) is another useful tool to tighten, smoothen and contour the aged skin.This is a noninvasive method to turn back the clock.

Choose your cleanser wisely

Choose your cleanser wisely

Good skin care starts with a clear skin.The first step to achieve clean skin is finding the right cleanser.Skin cleansing is an essential part of skin care and is necessary for skin health, hygiene and well being. Without effective cleansing your skin’s surface can accumulate debris,sweat, pollutants, excess oil and bacteria. Washing with water alone will rinse 65% of the oil and dirt on your skin, but its not quite enough. Skin cleansers work as emulsifiers and help remove dirt , excess sebum, bacteria, cosmetics, exfoliated surface skin cells by lowering the surface tension. Skin cleansers consists of the following:

Water
Surfactants
Moisturisers
Fillers
Preservatives
Fragrance
Dyes or pigments

Today there is a wide array of cleansers to choose from.But the layman has several mis- conceptions about their usage.The best cleansers are non-irritating,safe for sensitive skin and won’t clog pores or cause acne. The interaction of cleanser surfactants with the stratum corneum (uppermost layer of skin) proteins can be deleterious to skin. So an ideal cleanser should minimize damage while providing moisturizing benefits during wash. Majority of the population use soaps as cleansers ,but when you have a compromised skin, acne or other skin diseases you need to exercise some caution while cleansing.There are 3 major categoriesof cleansing agents
1.Soaps
2.Synthetic detergents
3.Lipid free cleansing agents.
Soaps are water soluble sodium or potassium salts of fatty acids. Soaps are made from fats and oils by treating them chemically with a strong alkali. The irritation potential of the soap is related to
alkalinity and fatty acid chain length. Continued use of soaps can lead to dry skin, barrier damage, redness and cause ithching as they have hard surfactants. Hence people with sensitive skin should select a cleanser w/ith a mild surfactant, acidic or neutral PH and with minimal skin residue. The type of cleanser that is best for you depends on your skin type.Oily skin tends to get better with a gel wash which helps to dissolve oil,make up,sunscreen etc.If you have normal skin use a foaming lotion cleanser.If your skin is dry or sensitive try a gentle creamy cleanser.Your dermatologist can help you to select an ideal cleanser for your skin.
