Definition of a periodic serum.

A periodic serum is a skincare product designed to respond to the skin’s needs through the different phases of the menstrual cycle. Essentially, it helps to minimize the effects of hormonal variations on the skin.

The “Woman” periodic serum range from Typology.

At Typology, we have designed and launched a range of products based on the menstrual cycle, named “Woman”. It’s made up of four serums, one for each week, which respond to the different skin issues that women go through during their menstrual cycle. Here are the details:

  • Hydrating and soothing serum for week 1:

    The state of your skin will vary thanks to your menstrual cycle. The first phase starts on the first day of your period, when your hormones are at their lowest level, which can lead to skin sensitivity. Inflammation and spots are very common. It’s important to use a hydrating skincare product during this phase to help your skin remain supple. Typology’s suggested serum 1 is designed to hydrate and soothe your skin. Use it for 7 days as part of your daily skincare routine. It contains hyaluronic acid, aloe vera, cornflower water and bisabolol.

  • Firming and brightening serum for week 2:

    Your estrogen levels are increasing little by little to hit their peak through ovulation. Throughout this phase, your skin may be dull and look a little tired. Typology’s suggested serum 2 is packed with vitamin C and fruit acids to firm and brighten your skin. Vitamin C is important for protecting your skin, as it works with vitamin E to fight against free radicals. It also helps to boost collagen and elastin production whilst brightening your skin and tackling excess melanin production.

  • Hydrating and purifying serum for week 3:

    Your estrogen levels start to fall throughout this phase and are replaced by progesterone, which stimulates sebum production and can leave your skin oily and shiny. It’s important to use a skincare product which helps to eliminate excess sebum and purify your skin. Typology’s suggested serum 3 is enriched with wheat and ginger extract to be both hydrating and purifying. Ginger is known for its cleansing, exfoliating and antioxidant properties. It helps to eliminate excess sebum and get rid of dead skin cells on the surface of your skin. As for wheat extract, it helps to nourish and protect your skin.

  • Mattifying and anti-blemish serum for week 4:

    During the last phase before a new cycle begins, your estrogen levels continue to fall and your sebaceous glands keep on producing sebum. This phase is known for the appearance of imperfections, such as blackheads, blocked and dilated pores, spots, and shiny skin. It’s important to use an exfoliating product to help fix these issues. Typology’s suggested serum 4 is enriched with marine algae extract and zinc. Zinc is known for its antioxidant, healing and exfoliating properties, and is perfect for oily skin because it regulates sebum production and unclogs blocked pores. This serum will help to tackle imperfections, with a healing and mattifying effect for your skin.
