Ampoules et sérums : comment les utiliser ensemble

If you've ever stood in front of your shelf wondering where a new ampoule is supposed to go, you're in good company. Most people reach for an ampoule with a routine already in place, a favorite serum or two, maybe a Retinal on certain nights, and the questions show up fast: does this replace what I'm already using, does it go on first, and is there such a thing as too much? The short version is that an ampoule is meant to join your routine, not take it over. The longer version is below, one question at a time.

Not at all, and it helps to think of the two as doing different jobs. An ampoule is an intensive course, a concentrated stretch of actives used for a defined period, while a serum is steady upkeep that stays in your routine long after. Ampoules for the course, serums for the long game. The Lab Drop 10/10/10 Multi GF Exo Advanced Recovery Ampoules are a good example of the format: 3 actives at 10% each (Exosome Encapsulated GF, Advanced GF-Retin Complex, and Bio-Stem Peptide Complex), 30 airless-pump ampoules of 3 mL each, and a 4-month protocol that works out to roughly 1 ampoule every 3 to 4 days at twice-daily use. 

At 4 weeks, results included a 109% improvement in radiance** and a 75% improvement in skin smoothness,** along with a 40% increase in hydration* and up to 35% improvement in the look of skin elasticity.* Individual results vary, which is one more reason the rest of your routine still counts. Cleanser, moisturizer, and sunscreen all stay. 

Before. Our directions are to cleanse, apply a hydrating mist, then use 1 to 3 pumps of the ampoule on damp skin (shake the ampoule well before each use), then apply your serum, then moisturizer, with a broad-spectrum SPF 50 closing out the morning. That runs against the usual advice to apply the thinnest texture first, and that's by design: the most concentrated step goes on first so the rest of your routine builds on it. 

Among your serums, the usual order still applies: exfoliating actives first, antioxidant and brightening serums next, and growth factor serums last. 

Multi Peptides & GF (Growth Factor) Advanced Lifting Serum is the serum we pair directly with the ampoule: keep using it through the full 4 months, applied after the ampoule and before moisturizer. Its 3% Growth Factor Complex works as a daily standing input, which makes it a natural companion to a course (89% of participants reported seamless makeup wear, self-assessment, 38 participants, 8 weeks). 

Peptides & Antioxidants Advanced Firming Daily Treatment is the step that seals everything in, morning and night. Formulated as a 5-in-1 moisturizer with 7 firming peptides, 9 antioxidants, and 13 brighteners, it can serve as your moisturizer step without another cream on top. 

For firmer-looking skin, Copper Tripeptide & Ectoin Advanced Repair Serum pairs Copper Tripeptide with 2% Ectoin and showed 1.6x faster skin recovery over 2 weeks. It goes on after the ampoule and ahead of the growth factor serum. 

For stubborn visible discoloration, Tranexamic & Arbutin Advanced Brightening Serum is the gentlest add-on, since it doesn't exfoliate: 3% Tranexamic Acid and 2% Alpha Arbutin, with 94% of users reporting brighter skin (self-reported). Azelaic & Kojic Advanced Clarifying Serum helps reduce the appearance of lingering post-breakout marks, with 84% of users seeing brighter skin and 43% seeing fewer dark spots after 28 days (self-reported). Mandelic Pigmentation Corrector Night Serum, an 11% blend of Mandelic, Lactic, and Salicylic Acids, is the exfoliating option. It belongs to the evening, on its own nights rather than layered with the ampoule, and it never shares a routine with the Copper Tripeptide serum. 

For dehydrated skin, Beta Glucan & Resveratrol Advanced Hydrating Serum brings an 8.75% Beta Glucan & Ceramide Complex, and after 2 weeks of twice-daily use, bioinstrumental analysis showed a 20% increase in skin moisture, alongside a 65% average increase in brightness and radiance that rose to 83% at 4 weeks (independent study, 32 participants). It's dermatologist-tested, fragrance-free, and layers under sunscreen and makeup without pilling. 

A sensible ceiling is 3 serums in a single routine, and the ampoule counts toward that number. In practice that means the ampoule plus 1 or 2 serums, picked by concern rather than stacked because they happen to be on the shelf. If a fourth is tempting, give it a different time of day or a different night instead of adding it to the same stack.

Yes, with a slower start. Because the ampoule is highly concentrated and includes Advanced GF-Retin Complex, we advise introducing Retinal, Vitamin C, and exfoliating acids gradually rather than all at once. Vitamin C belongs in your morning routine and retinoids, including Retinal, in your evening routine. Keep Vitamin C and exfoliating acids in separate routines too: Vitamin C is already acidic, so pairing the two is likely to cause irritation. Retinoids and acids don't share a night with each other either. 

Sensitive skin deserves a patch test before full-face use, and persistent redness, swelling, or irritation is a reason to stop and check with a healthcare provider. Anyone pregnant or breastfeeding should check with a doctor before using. 

Mornings run cleanser, mist, The Lab Drop 10/10/10 Multi GF Exo Advanced Recovery Ampoules on damp skin, your concern serum, the Multi Peptides & GF (Growth Factor) Advanced Lifting Serum, the Peptides & Antioxidants Advanced Firming Daily Treatment, and SPF. Evenings follow the same order without the sunscreen, and on exfoliating nights the Mandelic Pigmentation Corrector Night Serum takes the ampoule's place, followed by the Multi Peptides & GF (Growth Factor) Advanced Lifting Serum and the Peptides & Antioxidants Advanced Firming Daily Treatment. 

Choosing your serum is simple: reach for the Copper Tripeptide & Ectoin Advanced Repair Serum for firmness, the Tranexamic & Arbutin Advanced Brightening Serum or Azelaic & Kojic Advanced Clarifying Serum for tone and congestion, or the Beta Glucan & Resveratrol Advanced Hydrating Serum for hydration. Pick one, maybe two, and let the rest of the shelf wait its turn. 

Putting it together 

An ampoule works as a chapter in your routine rather than a rewrite of it. Keep the serums that already suit your skin, add the ampoule at the start of the sequence, and bring in actives gradually so there's room to see what each one is doing over the 4 months. The full protocol and the companion routine are available on our Bundles and Routines page.
