What is sugar in skincare?
Sugar appears in skincare in two quite different roles. As granulated sucrose it is the base of countless body scrubs; as a chemical precursor it is where glycolic acid – the most studied alpha-hydroxy acid – originally comes from, extracted from sugar cane.
Sugar is also a natural humectant, which is why a sugar scrub leaves skin feeling softer than a salt one, and why honey and molasses behave the way they do on skin.
What skin concerns does sugar treat?
As a body scrub it lifts dead cells and smooths rough patches on elbows, knees and legs. Its crystals are rounder and dissolve faster than salt, so it is the gentler of the two physical exfoliants.
For the face, the derived acid is what matters. Glycolic acid resurfaces, brightens, fades pigmentation and stimulates collagen – none of which a sugar scrub does. Scrubbing facial skin with crystals creates micro-tears and inflammation instead.
What ingredients are best paired with sugar?
In a body scrub, combine it with an oil – coconut, almond, jojoba – which cushions the abrasion and moisturises as you rinse. Use it before shaving, not after, and never on broken or sunburnt skin.
For facial exfoliation, use a formulated AHA: glycolic acid for resilient skin, lactic acid for dry or sensitive skin, or a PHA if acids usually sting. All deliver what a scrub promises, without the mechanical damage. 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.
