What is cetearyl alcohol in skincare?
Cetearyl alcohol is a blend of cetyl and stearyl alcohol, both fatty alcohols derived from plant oils such as coconut or palm. Despite the name it has nothing in common with drying alcohols like ethanol or isopropyl alcohol – it is a waxy solid, not a volatile solvent.
It works as an emollient, a thickener and an emulsifier, holding oil and water together so a cream stays a cream. It is one of the most common ingredients in moisturisers, conditioners and cleansing balms.
What skin concerns does cetearyl alcohol treat?
It softens and smooths the skin and helps reduce water loss, contributing to the barrier-supporting effect of the moisturiser it sits in. It gives rich creams their cushioned texture without a greasy finish.
It is generally very well tolerated, and safe for dry and sensitive skin. The two caveats: it is mildly comedogenic, so very acne-prone skin may find heavy creams built on it congesting, and contact dermatitis from cetostearyl alcohol is a recognised, if uncommon, reaction.
What ingredients are best paired with cetearyl alcohol?
It is a structural ingredient, so it appears alongside almost everything – glycerin and hyaluronic acid for hydration, ceramides and shea butter for barrier repair, and actives it helps deliver evenly.
If you have persistent unexplained reactions to moisturisers, fatty alcohols are worth raising with a dermatologist for patch testing. For most people, it is simply what makes a good cream feel good. Take our Skin Quiz.
What is hormonal acne?
Hormonal acne is acne whose timing and pattern track with hormonal activity rather than with cleansing habits or diet alone. It typically appears along the lower face – jawline, chin and upper neck – as deep, tender papules and cysts that flare on a predictable cycle.
It is most recognisable in adult women, where breakouts often arrive in the week before menstruation and settle again afterwards.
What causes hormonal acne?
Androgens – testosterone and DHT in particular – bind to receptors on the sebaceous gland and increase sebum production. When androgen activity rises or oestrogen falls, oil output climbs and follicles clog more readily.
Menstrual cycles, starting or stopping contraception, pregnancy, perimenopause and PCOS are the usual contexts. Stress raises cortisol, which amplifies the same pathway. Persistent hormonal acne with irregular cycles or excess hair growth is worth investigating medically.
What ingredients are best for hormonal acne?
Retinoids are the most effective topical, because they stop the plug forming regardless of how much oil is being produced. Azelaic acid reduces inflammation and the marks that follow, and niacinamide helps regulate sebum.
Salicylic acid keeps pores clear between flares, and benzoyl peroxide targets bacteria in inflamed lesions. Because hormonal acne is driven from the inside, topicals manage rather than cure it – consistency across the whole cycle beats spot-treating during a flare. Take our Skin Quiz.
