A good number of people breakout during winter and this happens for a good number of reasons.
The first and second reasons are the cold winter temperatures and their associated artificial heat from central heating which all play a role in drying the skin.
This dry skin is counterproductive for the management of acne since it makes the sebaceous (oil) glands produce more oil.
This increased oil production increases the chances of the pores being clogged and one developing pimples.
To prevent these types of breakouts, one should use a moisturizer which is non-comedogenic. This means that it will not clog skin pores and cause comedones (black and whitehead).
Since this oil-free moisturizer should be applied on a clean face, one should choose a gentle cleanser that will not strip the oils from the skin as it removes the grime. Click here to learn how to make Natural Face Cleansers.
After cleansing the skin, I would suggest skipping the toner which is likely to cause more drying, and applying a serum straight away followed by the moisturizer.
This should be a hydrating serum with acne treatment ingredients like tea tree essential oil. Click here to learn how to make Natural Acne Treatment Serums.
One scenario where I would recommend using a toner in someone breaking out in winter would be to freshen up in the morning if they do their major cleaning in the evening.
This wiping of the face with a cotton ball dipped in a toner would reduce the application of cleansers and prevent acne detergens which are the breakouts caused by excessive washing of the face.
If you choose to use toners, choose those which are alcohol-free since the alcohol also contributes to drying the skin. In addition, you should also reduce your oral alcohol intake from the parties that light up the winter since alcohol increases diuresis or water loss from the body.
After hydrating your skin topically through the application of acne treatment serums and water-based moisturizers, you should also hydrated it systemically by drinking at least 8 glasses of pure water each day.
If you cannot tolerate the tasteless taste of water, add ice cubes to every non-alcoholic drink that you take to increase their water intake.
Finally, consider taking an omega 3 fatty acid supplement if you are not able to consume adequate amounts of fatty fish like sardines or flaxseed oil.
