Our 20 best-selling products

C E Ferulic is a morning vitamin C serum that combines 15% pure vitamin C (L-ascorbic acid) with vitamin E and ferulic acid. SkinCeuticals says this antioxidant combination helps defend skin against environmental damage and visibly improves signs of ageing. It is SkinCeuticals' best-known product and the one our customers order more than any other, so it is usually where a SkinCeuticals routine starts.

Skin Caviar Luxe Cream is La Prairie's signature cream and the centre of its Skin Caviar line. It is a rich, velvety moisturiser made with caviar extracts and the brand's Exclusive Cellular Complex. La Prairie says it firms, lifts and smooths, and recommends it for dry to very dry skin. It is the luxury cream our customers buy most.

Triple Lipid Restore 2:4:2 is a barrier-repair moisturiser named after its ratio: 2% ceramides, 4% natural cholesterol and 2% fatty acids. SkinCeuticals says it restores the skin's essential lipids, and that it can shorten the adjustment period when you start using retinol. The texture is lightweight and absorbs quickly.

Crème de la Mer is the original La Mer cream, launched in 1965 and still the brand's best-known product. It is an ultra-rich moisturiser built on Miracle Broth, La Mer's fermented sea kelp. La Mer says it helps repair the skin barrier, hydrates, and softens the look of fine lines, and recommends it for drier skin.

P-TIOX is a peptide serum for expression lines, the creases that form from frowning, squinting and smiling. SkinCeuticals says it reduces the look of nine types of expression lines and gives skin a smoother, more radiant look within a week. It is needle-free, and SkinCeuticals says it can be used on its own or alongside injectable treatments.

Skin Caviar Liquid Lift is the lifting serum in La Prairie's Skin Caviar line. Caviar beads and a milky emulsion blend into a silky serum as you pump it. In La Prairie's own tests, users saw a visible lift within 15 minutes and a firmer jawline after eight weeks. It combines caviar extracts, peptides and the Exclusive Cellular Complex.

REJURAN's signature ampoule, also sold as the Healer Turnover Ampoule. It is a lightweight serum built on c-PDRN, DNA fragments derived from salmon, with niacinamide and hyaluronic acid. REJURAN says it smooths uneven texture, calms skin and boosts glow. It is a daily skincare step you use at home, not the Rejuran treatment given in clinics.

This set brings both Replasty creams together. Helena Rubinstein developed Replasty with the Swiss aesthetic clinic Laclinic Montreux, inspired by the care used after aesthetic procedures. The Age Recovery Day Cream is a light, soothing cream for sensitive, ageing skin. The Age Recovery Night Cream is the brand's rich repair cream, which it calls its "black bandage".

REJURAN's second ampoule, also sold as the Healer Dual Effect Turnover Ampoule. It pairs 0.5% c-PDRN with barrier-supporting ingredients: niacinamide, squalane, ceramide NP and cholesterol. REJURAN says it softens the look of fine lines and improves firmness and elasticity. Where the Turnover Ampoule (#7) focuses on texture and glow, this one is for firmness.

A.G.E. Interrupter Advanced is SkinCeuticals' anti-wrinkle cream for mature skin. It targets the visible effects of collagen loss and glycation, the process in which sugars stiffen collagen and which SkinCeuticals links to wrinkles, sagging and dullness. The texture is a rich, whipped cream. It is the cream, not the newer A.G.E. Interrupter Ultra Serum.

Replasty Age Recovery Night Cream is Helena Rubinstein's "black bandage": a rich night cream that melts into a light, velvety finish. It was developed with the Swiss aesthetic clinic Laclinic Montreux, and Helena Rubinstein says it accelerates the skin's recovery and repairs visible signs of ageing. The brand tested it on skin recovering from aesthetic procedures, and recommends it for all skin types, including the most sensitive.

Skin Caviar Luxe Eye Cream is the eye cream in La Prairie's Skin Caviar line, a rich ivory cream in a jar with a silver spatula. La Prairie describes it as a lifting and firming eye cream, and in its own eight-week tests it reduced the look of crow's feet, under-eye wrinkles and eye bags. It uses the same caviar extracts and Exclusive Cellular Complex as the Luxe Cream.

Physical Fusion UV Defense is SkinCeuticals' 100% mineral sunscreen, a sheer, tinted fluid with an SPF of 50. Its UV filters are zinc oxide and titanium dioxide, and translucent tinted spheres blend into the skin as you apply it. SkinCeuticals recommends it for all skin types, including very sensitive skin, and it is the most-ordered sunscreen on this list.

Platinum Rare Haute-Rejuvenation Elixir is a concentrated serum from La Prairie's Platinum Rare line, the most expensive product on this list. It combines colloidal platinum, a Platinum Multi-Peptide and the Exclusive Cellular Complex. La Prairie says it improves firmness and elasticity and reduces the look of fine lines and wrinkles. It comes in a vial with a pump and pipette.

Eau Parfumée au Thé Vert is the green tea fragrance Bvlgari created in 1992, first as a gift for its high jewellery clients. It was composed by perfumer Jean-Claude Ellena, and Bvlgari describes it as a citrus aromatic built around green tea, neroli and bergamot. It is the only fragrance in our top 20.

Hyaluronic Acid Intensifier Multi-Glycan, usually shortened to H.A. Intensifier, is SkinCeuticals' plumping serum. The current formula combines 1.3% pure hyaluronic acid with 12% Proxylane, 20% more than the previous version. SkinCeuticals says it plumps, improves the look of facial volume and contours, and hydrates for up to 48 hours. It is a lightweight, fragrance-free serum.

La Prairie's Protection Veil is a lightweight daily sunscreen that the brand calls "protection and treatment in one". It protects against UVA and UVB rays and gives long-lasting hydration, with a weightless, veil-like texture designed to sit under makeup. La Prairie now sells it as Protection Veil Sunscreen; it is still widely known as the Cellular Swiss UV Protection Veil.

A.G.E. Advanced Eye is SkinCeuticals' eye cream for dark circles, crow's feet and wrinkles linked to glycation, the same concern as A.G.E. Interrupter Advanced (#10). It combines Proxylane, flavonoids, peptides and caffeine with light-diffusing particles for the under-eye area. The texture is silky, and it is fragrance-free.

This is the eye and lip cream from Future Solution LX, which Shiseido calls its most luxurious skincare line. It is a dense, rich cream for the delicate skin around the eyes and lips, built on Shiseido's Enmei herb complex. Shiseido says it gives an immediately supported, lifted look and improves elasticity and hydration.

Skin Caviar Eye Lift is the eye serum in La Prairie's Skin Caviar line. Its dual-vial bottle combines two formulas in one pump, with caviar extract, caviar oil, peptides and hyaluronic acid. In La Prairie's own tests, users saw a visible eye lift within 15 minutes and denser-looking skin after four weeks.
