What is elastin in skincare?
Elastin is the dermal protein that lets skin stretch and snap back. It makes up a small fraction of dermal protein compared with collagen, but it does all the recoil – collagen provides strength, elastin provides spring.
The body essentially stops producing meaningful new elastin after adolescence, and existing fibres are progressively broken down by UV exposure in the process known as solar elastosis. That is why lost elasticity is harder to reverse than lost collagen.
What skin concerns does elastin treat?
Loss of elastin shows up as sagging, crepiness, skin that stays tented when pinched, and the loose texture around the jaw, neck and under-eyes.
Topical elastin cannot replace what has degraded – the molecule is far too large to reach the dermis – so in creams it acts as a humectant and film-former that smooths the surface. Oral elastin peptides have more support: a randomised placebo-controlled trial of fish-derived elastin peptide found improvements in biophysical properties of ageing skin.
What ingredients are best paired with elastin?
The practical route to elasticity is protecting and stimulating your own fibres. Retinoids and peptides signal fibroblasts to rebuild, vitamin C protects existing fibres from enzymatic breakdown, and daily broad-spectrum SPF prevents further elastosis.
Alongside those, hyaluronic acid, ceramides and squalane keep the skin hydrated and supple, which improves how elastic it looks day to day. Take our Skin Quiz.
What is dullness?
Healthy skin reflects light evenly, which is what reads as bright and glowing. Dull skin does the opposite – it looks flat, ashy, grey or sallow, and makeup tends to sit on top of it rather than blend in.
Dullness is not a condition in itself but a visible symptom: a build-up of dead cells, dehydration and reduced microcirculation that together stop light bouncing cleanly off the skin’s surface.
What causes dull skin?
Dead skin cells that do not shed naturally accumulate on the surface and scatter light unevenly. Dehydration flattens those cells so they no longer sit plump against one another, and overly dry skin can damage the follicles and slow the production of collagen and sebum – all of which make the complexion look duller or ashier.
Lifestyle and environment do the rest. Sun exposure, pollution, smoking, alcohol, broken sleep and stress all accelerate free-radical damage, while cell turnover naturally slows with age, so skin loses the reflectivity it had in your twenties.
What ingredients are best for dullness?
Brightening dull skin comes down to three things: gentle exfoliation, consistent hydration and antioxidant protection. Vitamin C, alpha-hydroxy acids such as glycolic and lactic acid, salicylic acid, retinol and vitamin A, niacinamide, green tea extract, coenzyme Q10 and rosehip oil all help resurface, even out tone and defend against free radicals.
Hyaluronic acid and hydrolysed collagen plump the skin so it reflects more light, and daily broad-spectrum sunscreen prevents the UV damage that dulls the complexion in the first place. Take our Skin Quiz to find the exact combination your skin needs.
