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 redness?
Facial redness is visible dilation of the small blood vessels near the skin’s surface. It ranges from transient flushing that comes and goes, to persistent erythema across the cheeks and nose, to fixed thread veins that stay visible all the time.
Redness is a symptom rather than a diagnosis. It can signal rosacea, irritation, an over-exfoliated barrier, eczema, an allergic reaction or simply reactive skin that responds strongly to heat and stress.
What causes redness?
Most persistent redness traces back to a compromised barrier and heightened nerve sensitivity. When the barrier thins, irritants penetrate more easily and the skin mounts an inflammatory response to things it would normally tolerate.
Common aggravators: over-exfoliation, high-strength actives used too often, fragrance and essential oils, hot water, alcohol, spicy food, sudden temperature change, sun exposure and stress. Trying to treat redness with more actives usually deepens it.
What ingredients are best for redness?
Prioritise calming and rebuilding over correcting. Niacinamide, azelaic acid, centella asiatica, green tea extract, liquorice root, allantoin, bisabolol and colloidal oatmeal all reduce visible inflammation.
Then repair the barrier with ceramides, cholesterol, fatty acids, glycerin, panthenol and squalane, and protect it with a gentle mineral SPF. Strip the routine back to cleanser, moisturiser and sunscreen for a few weeks before reintroducing anything active. Take our Skin Quiz.
