What is vitamin A in skincare?
Vitamin A is the parent of the entire retinoid family. In skincare it appears in several forms of increasing strength: retinyl esters, retinol, retinaldehyde, and prescription retinoic acid (tretinoin).
Every form except retinoic acid must be converted by the skin before it can act – each conversion step costs potency, which is why retinyl palmitate is mild and tretinoin is powerful. Vitamin A regulates how skin cells mature, turn over and produce collagen.
What skin concerns does vitamin A treat?
It is the most versatile active in dermatology: fine lines and wrinkles, loss of firmness, uneven tone and pigmentation, enlarged pores, rough texture, and acne at every severity.
Because it works at the level of cell behaviour rather than the surface, results are gradual and cumulative – expect twelve weeks before meaningful change, and continued improvement for a year or more.
What ingredients are best paired with vitamin A?
Pair it with hyaluronic acid, ceramides, niacinamide, squalane and panthenol to absorb the dryness and flaking of the adjustment period. Introduce it two nights a week and build up.
Use it at night only, and wear broad-spectrum SPF daily – vitamin A increases photosensitivity and is degraded by light. Avoid combining it with AHAs, BHAs or benzoyl peroxide in the same step, and avoid retinoids entirely during pregnancy. 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.
