Esthetic House Collagen

The standout format in this collection is the 1,000ml size. The 1 Collagen Skin 1000ml and the 1 Large-capacity Collagen Lotion 1000ml are both offered in pro-grade quantities that are far above a standard retail bottle. A typical toner runs 150ml to 200ml, so a 1,000ml version holds roughly five to six months of daily use at a cost-per-ml well below smaller retail formats. The lotion follows the same logic: a 1,000ml bottle means you can apply multiple layers without measuring out every drop.

These sizes suit people who have already decided collagen hydration is a daily staple and want to reduce repeat purchases. They also suit households where two or more people share the same product, or anyone running a professional or semi-professional skincare workflow.

The XV Marine Collagen sub-line features marine-derived collagen, which is extracted from fish scales or skin and carries smaller peptide fragments than bovine collagen. The XV Marine Collagen Essential Skin at 150ml is a standard retail size and can be used as a first toner step focused on marine collagen delivery. The XV Marine Collagen Eye Cream at 30ml is the targeted option for the delicate under-eye area, where collagen loss shows earliest as fine lines and hollowing. Eye cream application is most effective with ring-finger tapping rather than rubbing, which avoids stretching the thin periorbital skin.

The XV naming suggests this sub-line is positioned as a higher-specification tier within Esthetic House, which is consistent with the move to marine collagen over standard hydrolyzed collagen.

The Formula Ampoule Peptide IEX at 55ml is the concentrated treatment step in this collection. Peptides are shorter amino acid chains that can signal the skin to support structural proteins, including collagen. An ampoule format delivers these at higher concentration than a toner or lotion, which is why it sits in the routine after toners and before cream. At 55ml it is a standard ampoule size meant for targeted use rather than all-over generous application. It pairs with any of the collagen toner or lotion steps as an add-on for firming focus.

The 1 Collagen Skin (toner) and the 1 Large-capacity Collagen Lotion serve different routine positions. The skin (toner) is thinner and goes on first after cleansing; it soaks in quickly and prepares the surface for the next step. The lotion is thicker and more emollient, sitting later in the routine and providing a longer-lasting moisture barrier. If you want both hydration and barrier support, buying the toner to apply first and the lotion to apply second gives a two-step foundation before serums or creams. If you only want one product, dry skin benefits more from the lotion; oily or combination skin is often satisfied by the toner alone.

A complete Esthetic House collagen routine works in this order: cleanse, then apply the large-capacity collagen skin (toner) in two to three pats, let it absorb, then apply the collagen lotion, then the Formula Ampoule Peptide IEX for targeted firming. Finish with the XV Marine Collagen Eye Cream around the orbital bone for the eye area, then a moisturizing cream and SPF. The XV Marine Collagen Essential Skin can replace the large-format toner if you want a smaller bottle or prefer marine collagen at the first step. Morning and evening routines can follow the same order, though the peptide ampoule is often reserved for the evening when skin repair activity is higher.

Collagen applied topically works at the surface. Hydrolyzed collagen peptides form a temporary moisture-holding film and may signal fibroblasts in the upper dermis to increase their own collagen synthesis. Marine collagen, as used in the XV line, carries smaller peptide fragments than bovine collagen, which some researchers associate with slightly better surface penetration. Neither type replaces the collagen lost with age, but consistent topical use supports the skin's hydration and the appearance of firmness over time. The large 1,000ml format makes consistent use practical by removing the barrier of running out.

The 1,000ml collagen skin and lotion are designed for broad compatibility. Oily skin types may use the collagen skin toner daily but find the lotion too heavy for morning wear; reserve the lotion for nighttime in that case. Normal and combination skin can use both steps morning and evening. Dry skin benefits the most from the lotion's emollient base. The XV Marine Collagen Eye Cream at 30ml suits all skin types around the eye area. The peptide ampoule is generally well-tolerated, but if your skin reacts to actives, introduce it every other evening before using it daily.
