Noncomedogenic Skin Care and Make Up


A reader Simran asked me yesterday - What does Noncomedogenic mean? 

I hope the post below helps :) 
Noncomedogenic is a term applied to oils, lotions, and skin creams that do not block pores.
Non-comedogenic cosmetics are tested on the oily skins of human volunteers or inside rabbit ears. These products are less likely to cause blackheads (open comedones) or whiteheads (closed comedones) in patients. However, no single product is non-comedogenic for everyone.
Noncomedogenic products are also sometimes referred to as non-occlusive. The theory behind using lotions that are noncomedogenic is that by not blocking pores, they will reduce the incidence of pimples.
While there is some evidence that noncomedogenic products may, by not blocking pores, reduce acne, this has not been proven in clinical trials and has not been tested by the US Food and Drug Administration (FDA).
Much evidence exists, however, which attests to the value of noncomedogenic products. Occluded pores are more likely to produce acne, particularly if one is prone to acne. However, some forms of acne result from more than one cause, like the presence of a high number of streptococcus bacteria on the skin. In such cases, using a noncomedogenic product may not significantly reduce acne.
If making one’s own skin care products, the best choices of noncomedogenic oils include almond, olive, evening primrose, peanut, safflower, and sunflower oils. Oils like corn, castor, cottonseed and hydrogenated vegetable oil will occlude the pores somewhat. Oils made from coconut, cocoa butter, and wheat germ are considered very occlusive.
Many makeup products can clog the pores of the skin, or leave skin excessively greasy. This can lead to skin irritation and breakouts, and is also likely to exacerbate any existing skin problems. For this reason many people choose to use noncomedogenic products, which are makeup products that do not clog pores.
Noncomedogenic products are also called non-occlusive makeup products, and are particularly suitable for people with acne or sensitive skin. In addition to foundations, skin care products such as cleanser and moisturizer are also available as noncomedogenic formulations. Many noncomedogenic cosmetics are also oil-free, which further helps to reduce acne in people with oily skin.
Skincare With Non-Comedogenic Cosmetics
Moisturizers:
There are plenty of oil-free and thicker moisturizers available in the market today that are non-comedogenic, however if you are exercising or if the air is hot and humid (think Mumbai weather), these moisturizers may become comedogenic.
Cleansers:
 Care must be taken not to over dry the skin with a strong cleanser for fear that the skin will re-bound with extra oil. Often a good gentle face bar soap, (e.g. Neutrogena bar, Dove, Oil of Olay) gentle cleansers such as Cetaphil lotion, should be good enough

When the patient actually has acne and not just oily skin, many acne cleansers are available. Neutrogena, Clinique, Clearasil, Clean and Clear and many other companies have cleansers made specifically for acne. There are benzoyl peroxide cleansers in the form of 5 and 10 % bar soaps and liquid cleansers, which are very effective in controlling acne breakouts.

Foundations:
Look for foundations with titanium dioxide which allows for better coverage, and is not oily, varying amounts of starch and kaolin will thicken up the products without causing acne and also help absorb excess oil. The best example of this is Lacto Calamine lotion

The addition of 1-2% salicylic acid may be partially therapeutic. Revlon concealors are formulated with salicylic acid.
Sunscreens:
The active ingredients of sunscreens UVB blockers such as Cinnamates, Octocrylene, Salicylates, and UVA blockers such as Benzophenones, Parsol 1789 (avobenzone), micronized zinc or titanium dioxide, are not themselves comedogenic. The least comedogenic sunscreens are usually gel formulations

Skin Care Myth: Sunscreen will stop you from Tanning

Image via Wikipedia I know I did a recent article on skin care myths (read it here), but I don't know how I forgot to mention this particular myth. In any case I think this warranted a post on its own.

Myth: If I use a suncreen regularly and religiously, I will not tan. 

Fact: This is a very simplistic statement. But before I bust this myth, kindly bear through a science lecture. This is to bring all readers of all backgrounds on the same knowledge level.



Lets define sunscreen (from Wikipedia):Sunscreen (also commonly known as sunblock or sun cream) is a lotion, spray, gel or other topical product that absorbs or reflects "some" of the sun's ultraviolet (UV) radiation on the skin exposed to sunlight and thus helps protect against sunburn. Sunscreen helps protect only against direct DNA damage as it cannot dissipate UV as harmless heat.

The SPF of a sunscreen is a laboratory measure of the effectiveness of sunscreen — the higher the SPF, the more protection a sunscreen …

Reetha, Amla & Shikakai Home Made Shampoo - Weekend Experiment

Good Morning Lovelies, I hope your weekend was fun. Mines was, well, ho-hum, but anyways, we are not talking about that here (let’s save that cribbing for twitter).
I have been suffering from quite a bit of hair fall since some time. I have tried changing products to using intensive conditioning and the works. It stops the hair fall for while, but then it rears its ugly head again.
So on lark, & for lack of better things to do, my best friend & I decided to make some Reetha – Amla – Shikakai shampoo at home. This century old ayurvedic herbal concoction is reputed to not only strengthen hair, but also darken it and stop hair fall.
I got the 3 biggies from a local kirana store. All 3 are priced at 15 Rs for 100gms.

How to: Soak 5 pieces of Shikakai, 4 balls of Reetha  (Soapnut) & handful of Amla (Indian Gooseberry)  in about 500 ml of water overnight. In the morning, heat the mixture on gas till it just starts to boil. Let it cool, when lukewarm mash all the amla, reetha and…
