What is lavender in skincare?
Lavender oil is steam-distilled from the flowering spikes of Lavandula angustifolia. Its main constituents are linalool and linalyl acetate, which give it both its scent and its biological activity.
It is one of the most widely used essential oils in cosmetics, valued for fragrance as much as for function. Its anti-inflammatory and antimicrobial properties are real, but so is its potential to sensitise skin.
What skin concerns does lavender treat?
It calms minor irritation, insect bites and small wounds, and has been shown to support wound healing and collagen synthesis in experimental models. Its antibacterial action gives it a modest role in mild acne.
Its most reliable benefit is arguably indirect: lavender’s effect on stress and sleep quality matters for skin, since cortisol drives inflammation and breakouts. As a topical active on the face, however, it is one of the weaker options.
What ingredients are best paired with lavender?
Always dilute it in a carrier oil – jojoba, squalane or sweet almond – to around 1%. Pair it with calming ingredients such as chamomile, centella asiatica and colloidal oatmeal.
Be cautious: linalool oxidises on exposure to air into a known contact allergen, and lavender is a common cause of fragrance sensitivity. If your skin is reactive or you are treating rosacea, a fragrance-free calming ingredient is the safer choice. Take our Skin Quiz.
What is cystic acne?
Cystic acne is the most severe form of inflammatory acne. Instead of surface pimples, it produces deep, tender nodules and fluid-filled cysts that sit under the skin, often without ever coming to a head.
It happens when a blocked follicle ruptures deep in the dermis and spills sebum, keratin and bacteria into surrounding tissue, triggering a strong immune inflammatory response. Because the damage is deep, cystic acne is the type most likely to scar.
What causes cystic acne?
The same four factors behind all acne, amplified: excess sebum, abnormal shedding inside the follicle, overgrowth of Cutibacterium acnes, and inflammation. Androgens drive sebum production, which is why cystic acne often tracks with hormonal cycles, PCOS or puberty.
Genetics strongly influence severity, and stress, high-glycaemic diets, occlusive products and picking at lesions all make it worse. Squeezing a cyst pushes the contents deeper and reliably increases scarring.
What ingredients are best for cystic acne?
Cystic acne genuinely warrants a dermatologist – oral treatment is often needed. Alongside that, topical retinoids are the most useful over-the-counter active, because they work on the plug before it ruptures.
Benzoyl peroxide reduces bacterial load, azelaic acid calms inflammation and post-acne marks, and niacinamide helps redness without irritation. Keep the rest of the routine gentle and barrier-focused – harsh scrubs and drying alcohol make deep lesions angrier. Take our Skin Quiz.
