GLP-1 skin changes call for a different kind of skincare.

Rapid weight loss can leave skin drier and less elastic, and a loss of fat volume can show as hollowed cheeks and sagging. Meticulous was built for that stretch of change.

Why your skin feels different now.

  1. Drier-feeling skin

    Skin barrier

    Reduced appetite and lower fluid intake can lead to dry, flaky, or less elastic skin.

  2. Less firm-looking skin

    Support layer

    Collagen and elastin give skin its strength and spring. Rapid weight change can outpace that support, and skin reads as less firm.

  3. Less facial fullness

    Facial fat

    Rapid weight loss causes a loss of subcutaneous fat volume, leading to hollowed cheeks, sagging skin, and wrinkles.

Care built around the GLP-1 journey.

Significant weight change can bring new concerns into focus. Meticulous is building a focused approach with skincare for visible skin concerns and supplements for separate daily-support needs.

Skincare · Available now

Formulas for the appearance and feel of skin during significant weight change.

Supplements · Coming soon

A distinct layer of daily support, separate from the skincare routine.

Start with what fits you. Every product stands on its own.

In our Meticulous study

About these photographs

Participant-submitted photography, unretouched, with no colour correction. Lighting, angle and conditions vary between panels. Each panel shows one individual's experience at the timepoints noted. Individual results vary, and nothing here is presented as a typical or expected outcome. This is an internal study, not an independent clinical trial. These are the two topical skincare products; the Protocol supplements were not part of the study.

Scott Kanyok, founder of Meticulous

The founder

Our founder has spent his career in ingredient innovation. That focus led him to notice people on GLP-1s experiencing an unusual kind of aging, and he built the formulas around it.

The Longevity Hybrid Defense Serum and Revolumizing Bioactive Moisturizer textures on glass blocks in daylight

A purpose for every active.

We start with the person navigating a GLP-1 journey and the needs we’re designing for. Research guides the ingredients we select for our skincare and supplements.

We use multiple actives because they have distinct roles. Each choice is considered on its own evidence, form and place within the formula.

Topical skincare

The Longevity Hybrid Defense Serum in a black dropper bottle.

Longevity Hybrid Defense Serum™

Multi-pathway skin defense and moisture barrier support for the visible effects of GLP-1 weight loss.

Explore the formula

  • Four-form vitamin C blend

    Combines L-ascorbic acid, tetrahexyldecyl ascorbate, 3-glyceryl ascorbate and magnesium ascorbyl phosphate to support antioxidant defense and brighter, more even-looking skin.

    Human topical research supports antioxidant and visible-tone roles for vitamin C. Performance depends on the form, stability, concentration and complete formula.

  • Ferulic acid + alpha-tocopherol (vitamin E)

    Antioxidant partners selected to complement the vitamin C system and help defend skin from environmental free radicals.

    Human topical studies have evaluated vitamin C, vitamin E and ferulic acid combinations. Those studies did not test the Meticulous serum.

  • Resveratrol + fulvic acid

    Additional antioxidant and skin-conditioning support within the serum.

    Research supports antioxidant activity at the ingredient level, but the amount and quality of human topical evidence vary.

  • Açaí fruit extract

    A botanical antioxidant and conditioning ingredient.

    The published ingredient list identifies this as Euterpe oleracea fruit extract, named on the label as açaí stem cells.

  • Triple Peptide Complex

    Selected to support the appearance of firmness and tone.

    The published ingredient list identifies the complex as almond seed extract, yeast extract and hydrolyzed wheat protein. Triple Peptide Complex is its marketed complex name, not a statement that three peptides have been independently identified.

  • Sodium hyaluronate

    A humectant that helps bind water at the skin’s surface for a more hydrated, supple appearance.

    Sodium hyaluronate appears on the published list for both topicals. Hyaluronic-acid ingredients are widely studied for topical hydration; this does not establish a finished-product result.

The Revolumizing Bioactive Moisturizer in a black pump bottle.

Revolumizing Bioactive Moisturizer™

Facial volume support and hydration for the visible effects of GLP-1 weight loss.

Explore the formula

  • Green tea extract + ergothioneine + fulvic acid + reishi extract

    A second antioxidant and conditioning layer within the moisturizer.

    These ingredients have supportive laboratory, ingredient-specific or limited human evidence. They have not been shown to produce a combined synergistic effect in this formula.

  • Ornithine + palmitoyl dipeptides

    Selected to help skin look firmer, more resilient and more cushioned.

    Human cosmetic research exists for some topical palmitoyl peptides, and that evidence is specific to the peptide and formula studied. These ingredients do not replace facial fat or rebuild underlying volume.

  • Adipo Restore Complex™

    The public name for the moisturizer’s group of peptides, postbiotic ingredients, lipids and hydrators.

    A proprietary grouping of ingredients that appear on the published list. It is not a separately tested active.

  • Niacinamide + Ceramide NP

    Selected to support the skin barrier, hydration and smoother-looking texture.

    Human topical research supports barrier and hydration roles for niacinamide- and ceramide-containing products, although results cannot be transferred automatically to this formula.

  • Phospholipids + glycolipids + squalane

    Emollient and lipid-supporting ingredients that help soften skin and reduce moisture loss.

    Their established cosmetic roles support the formulation rationale; this grouping has not been tested independently.

  • Glycerin + panthenol + beta-glucan + tremella + ectoin + oat

    A group of humectant, soothing and conditioning ingredients selected to support comfortable, hydrated-looking skin.

    Glycerin also appears on the serum’s published list; the rest of this group is specific to the moisturizer. Evidence ranges from established humectant use to ingredient-specific and emerging research, and the group has no demonstrated synergy.

  • Sodium hyaluronate

    A humectant that helps bind water at the skin’s surface for a more hydrated, supple appearance.

    Sodium hyaluronate appears on the published list for both topicals. Hyaluronic-acid ingredients are widely studied for topical hydration; this does not establish a finished-product result.

  • Lactobacillus ferment + Lactobacillus rhamnosus ferment lysate

    Postbiotic cosmetic ingredients selected for skin conditioning and comfort.

    Research in topical postbiotic ingredients is emerging and highly ingredient-specific. The moisturizer is not presented as changing or balancing the skin microbiome.

Supplements

Protocol io in a black supplement jar.

Coming soon

Protocol io™

Whole-body cellular defense supporting inflammatory balance, oxidative stress, and mitochondrial energy during the GLP-1 journey.*

Explore the formula

  • Glutathione + ergothioneine + astaxanthin

    Selected to support the body’s antioxidant defenses and healthy oxidative balance.*

    Human research exists for individual oral antioxidants and antioxidant markers. It does not establish results for Protocol io or show that the combination works better than the ingredients individually.

  • Plant-derived vitamins C and E + fulvic acid trace minerals

    Nutrient and antioxidant support intended to complement, not replace, a balanced diet.*

    Evidence and recommended use differ by nutrient and form. This is not a statement that the product corrects a deficiency or detoxifies the body.

  • Nicotinamide riboside + CoQ10 + PQQ

    Selected for complementary roles in cellular energy metabolism.*

    Human research has evaluated these ingredients individually and in specific contexts. No finished-product result, weight change or increase in energy is claimed.

  • Palmitoylethanolamide (PEA)

    Selected to support a healthy inflammatory response and everyday physical comfort.*

    Human research exists in specific populations and applications. Protocol io is not offered for pain or inflammation, and no claim is made about GLP-1 medications and inflammation.

Protocol nr in a black supplement jar.

Coming soon

Protocol nr™

Restorative sleep and nighttime cellular recovery support throughout the GLP-1 journey.*

Explore the formula

  • Magnesium bisglycinate + L-theanine

    Selected to support relaxation, a calm stress response and restful sleep.*

    Human research supports these roles in specific forms and study conditions. Protocol nr itself has not been tested.

  • L-glycine + L-taurine + phosphatidylserine + apigenin + honokiol + vitamin B6 as P5P

    Ingredients selected for complementary roles in nervous-system support and the nighttime recovery routine.*

    The strength of human evidence varies substantially by ingredient. No claim is made about how quickly sleep arrives, how long it lasts, cortisol, or next-morning performance.

  • Hyaluronic acid

    Selected to support skin hydration from within.*

    Randomized human studies have evaluated oral hyaluronic acid for skin hydration at studied doses. Those studies did not test Protocol nr.

  • Full-spectrum berry polyphenols

    Selected for antioxidant support within the nighttime formula.*

    Research varies by berry source, extract and dose. Combining several sources has no demonstrated advantage.

Ingredient summaries describe research on individual ingredients or comparable forms. They explain why an active was selected; they are not evidence that a finished Meticulous product will produce the same result.
