"For the first three months, skin can actually be more prone to spots,” explains Cassie Lomas, Bourjois make-up artist who spent much of 2009 touring with Lady Gaga until giving birth to her son at the end of the year.
She says hormonal changes mean skin often produces more oil so women who’ve never experienced spots suddenly find them popping up regularly while women with already spot-prone skin can find the problem exacerbated.
Cassie recommends avoiding full foundation to reduce the clogging of pores that are already filling with oil and, instead, patting a solid concealer - which gives greatest coverage of all formulations - onto the skin over and around blemishes. Finish with a dusting of mineral powder to keep the concealer in place and mop up oiliness without, again, clogging pores.
She advises cleansing with tepid water, to make sure all make-up is thoroughly removed while also cooling skin and used Bourjois Foaming Cleansing Cream, £4.88, while she was pregnant.
Luckily, Cassie says the problem usually subsides in the second trimester, which is when the ‘bloom’ starts to appear – a possible result of increased heart rate and circulation during pregnancy which sees blood rushing to the surface.
However, skin can remain unusually sensitive, developing reactions even to products that have been used before without a problem. Cassie advises removing the offending product with cool water immediately redness or stinging develops.
Using organic products may also reduce the risk of irritation, not least because the fewer the ingredients of any product, the less the chance of a reaction.
