You might have already noticed some of these changes, but here’s a complete guide on what you might expect during the different phases of your cycle and how you can adapt your skin care a little to help compensate these changes. Of course everyone is different but you can take notes in the Natural Cycles app to keep track of changes and maybe even tweak your skin care routine.

Period: skin is dry

In the beginning of your cycle, which starts on the first day of your period (Cycle Day 1), your levels of both progesterone and estrogen are quite low. This can cause skin to feel drier and wrinkles might become more obvious.

Tip: Pamper your skin, use gently cleansers and products designed to plump and hydrate your skin.

Follicular phase: skin is stronger

Your ovaries resume the production of estrogen as your period ends, which plumps the skin and encourages collagen production. This gives your skin strength and it will look very plump and healthy. In fact, your skin is not as sensitive to pain during this time.

Tip: Carry out hair removal or skin peelings for dry skin patches during this time.

Ovulation: skin is healthy and plump

This is often the time of the month where you are at your best. You feel great and your skin is healthy and plump. Increased estrogen means collagen is high but it can also lead to some pimples for some women as spots in your skin can get oilier.

Tip: If your gonna get some passport photos taken, do it now 

Luteal Phase: skin is oily and prone to break out

Once you ovulate, your body starts producing the hormone progesterone. Which we know to cause the temperature also rise. Progesterone stimulates the production of sebum, which is a thick and oily substance that acts a natural skin lubricant. Which can ultimately also cause pores to clog up and be the cause of breakouts.

Tip: Soak up excess oil on the skin surface with a purifying and detoxifying mask.

PMS: skin is puffy

Some women tend to retain water during this time and skin looks puffier. Also because you tend to crave junk food and sugary treats your skin might suffer.

Tip: Do your best to stick to healthy foods and keep water intake high.
