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 acne?
Acne vulgaris is a chronic inflammatory condition of the pilosebaceous unit – the hair follicle and its attached oil gland. It produces blackheads and whiteheads, inflamed papules and pustules, and in severe cases deep nodules and cysts.
It is the most common skin condition worldwide, and it is not a hygiene problem. Acne begins with a microcomedone forming invisibly inside the follicle, weeks before anything shows on the surface.
What causes acne?
Four mechanisms work together: excess sebum driven by androgens, abnormal shedding of cells inside the follicle, overgrowth of Cutibacterium acnes, and the inflammatory response that follows.
Genetics set the baseline. Hormonal fluctuation, stress, high-glycaemic diets, comedogenic products, friction from masks or helmets, and certain medications all push it further. Over-cleansing and picking make it visibly worse.
What ingredients are best for acne?
Salicylic acid clears inside the pore, benzoyl peroxide reduces bacterial load, and retinoids prevent the plug forming in the first place – that last one is the most valuable long-term.
Azelaic acid and niacinamide reduce inflammation and the marks left behind, and sulphur or clay help oily, congested skin. Keep the barrier intact with a gentle cleanser and a light non-comedogenic moisturiser; stripped skin produces more oil. Take our Skin Quiz.
