The Ordinary buying guide: choosing the right active
The Ordinary builds each product around one job. Instead of a single cream that promises everything, you reach for a serum when you want hydration and a solution when you want to even out tone, each priced for what is inside the bottle. The grid at skinsli carries the peptide serums, the acid and antioxidant solutions, the hyaluronic hydrators, and the cleansers that make up a working routine. This guide walks through how to read the range and pick the formulas that match your skin.
Why single-ingredient formulas
The whole range is built so you can isolate one active per step. Marin Hyaluronix handles hydration, EUK 134 covers antioxidant defence, and a peptide serum like Buffet targets the look of fine lines. Because each formula commits to one purpose, you can add or drop a step without rebuilding your entire routine. That also keeps the price down, since you pay for the ingredient you came for rather than a long list of claims.
Peptide serums for firmness and fine lines
Buffet and the Multipeptide + HA Serum are the firmness-focused picks in this grid. They pair a blend of peptides with hyaluronic acid, so you get support for the look of lines alongside surface hydration in one layer. Peptides are gentle enough to use morning and night, and they play well with almost everything else in the range. If you want one anti-ageing step that does not fight your other actives, start here.
Hyaluronic acid and hydration
Marin Hyaluronix and the HA inside the peptide serums cover the hydration side of a routine. Hyaluronic acid pulls water into the upper layers of skin, which softens the look of dryness and gives later steps something to seal in. Apply it to slightly damp skin, then follow with a moisturiser or oil so the water it draws does not evaporate. This is the step most dry or dehydrated skin types feel first.
Brightening and tone-evening solutions
The azelaic-style and Azirelin solutions in the lineup target uneven tone, dullness, and the marks left behind after breakouts. These are leave-on treatments you work in after cleansing and before heavier creams. Introduce one brightening active at a time and give your skin a few weeks to respond before you judge it. Pairing a brightening solution with daily sunscreen protects the progress you make.
Antioxidants and vitamin C derivatives
EUK 134 and the Ascorbyl Tetraisopalmitate Solution sit in the antioxidant corner of the range. Antioxidants help defend skin against the daily stress of light and pollution, and the vitamin C derivative offers a gentler route to brightening than pure ascorbic acid for sensitive types. These work best in the morning under sunscreen, where their protective role does the most good. They layer cleanly over a hydrating serum.
Cleansers to start the routine
The Squalane Cleanser is the gentle first step for the whole range. Squalane lifts makeup and sunscreen without stripping skin, so it suits dry and sensitive types that react to foaming washes. Massage it onto dry skin, then rinse or wipe it away, and your actives go onto a clean surface that can absorb them. A non-stripping cleanse keeps the rest of a treatment routine from feeling harsh.
How to layer the steps
Order matters once you run several actives. A workable sequence is cleanse, then water-based hydration like Marin Hyaluronix, then your targeted serum or solution, then moisturiser, with sunscreen in the morning. Thinnest textures go first so the heavier ones do not block them. Do not stack every brightening and antioxidant active in one sitting; alternate them across morning and night so you are not asking your skin to process too much at once.
Picking by skin concern
Match the bottle to the problem you want to solve. Dehydration points to Marin Hyaluronix. The look of fine lines points to Buffet or the Multipeptide serum. Uneven tone and post-breakout marks point to the brightening solutions, while dullness and daily defence point to EUK 134 or the vitamin C derivative. With more than a hundred formulas in stock here, the safer path is to fix one concern at a time rather than buying the whole shelf at once.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
What does The Ordinary Buffet serum do?
Buffet is a multi-peptide serum that pairs several peptide complexes with hyaluronic acid. It targets the look of fine lines and supports skin firmness while adding lightweight hydration in the same step. It is gentle enough for morning and night use and layers under moisturiser.
How is Marin Hyaluronix used in a routine?
Marin Hyaluronix is a hyaluronic acid hydrator. Apply it to slightly damp skin after cleansing and before heavier creams, then seal it with a moisturiser so the water it draws does not evaporate. It is the hydration base most dry or dehydrated skin types start with.
What is EUK 134 and when should I apply it?
EUK 134 is an antioxidant solution that helps defend skin against daily stress from light and pollution. It works best in the morning under sunscreen, layered over a hydrating serum. Introduce it on its own first so you can see how your skin responds.
Is the Ascorbyl Tetraisopalmitate solution gentler than pure vitamin C?
Yes. Ascorbyl Tetraisopalmitate is a vitamin C derivative that offers a milder route to brightening than pure ascorbic acid, which suits sensitive skin that finds straight vitamin C irritating. Use it in the morning under sunscreen for the best protective and tone-evening effect.
How do the brightening solutions help with post-breakout marks?
The azelaic-style and Azirelin solutions target uneven tone, dullness, and the marks left after breakouts. Work one in after cleansing as a leave-on treatment, add only one brightening active at a time, and give it a few weeks. Daily sunscreen protects the tone progress you make.
Who is the Squalane Cleanser best for?
The Squalane Cleanser suits dry and sensitive skin that reacts to foaming washes. Squalane lifts makeup and sunscreen without stripping, so it leaves a clean surface for your actives to absorb into. Massage it onto dry skin, then rinse or wipe it away.
What order should I layer The Ordinary products?
Go thinnest to thickest: cleanse, then water-based hydration like Marin Hyaluronix, then your targeted serum or solution, then moisturiser, and sunscreen in the morning. Avoid stacking every brightening and antioxidant active at once; alternate them across morning and night.
Why is The Ordinary priced so low?
Each formula commits to one active and skips multi-claim marketing, so you pay for the ingredient rather than the packaging. That single-purpose approach is the reason a peptide serum or hydration solution here costs far less than a do-everything cream.
