# Glycolic acid and collagen peptide Page: https://lovi.care/skincare/es/ingredients/glycolic-acid-and-collagen-peptide The Lovi Fit is the same in every country; only the stores and prices differ, and the ones here are for Spain. Keep them apart Use them at different times of day, applying [glycolic acid](https://lovi.care/skincare/es/ingredients/glycolic-acid) in the morning and [collagen peptide](https://lovi.care/skincare/es/ingredients/collagen-peptide) at night, because the acid is too harsh. The strong acid breaks down the peptide and stops it from working properly. You can easily fix this by using them in separate routines or waiting longer between steps. - [All about glycolic acid](https://lovi.care/skincare/es/ingredients/glycolic-acid) - [All about collagen peptide](https://lovi.care/skincare/es/ingredients/collagen-peptide) ### [Glycolic acid](https://lovi.care/skincare/es/ingredients/glycolic-acid) products - [The Ordinary Glycolic Acid 7% Toning Solution](https://lovi.care/skincare/es/p/the-ordinary/glycolic-acid-7-toning-solution/for/combination-skin) — Superior fit — [€13.90 at Amazon](https://www.amazon.de/dp/B071914GGL?tag=lovi-care-web-product05-21&linkCode=osi&th=1&psc=1) - [RoC Retinol Correxion Deep Wrinkle Night Cream](https://lovi.care/skincare/es/p/roc/retinol-correxion-deep-wrinkle-night-cream/for/dark-spots) — High fit — [€33.98 at Amazon](https://www.amazon.de/dp/B0GXBBV93V?tag=lovi-care-web-product05-21&linkCode=osi&th=1&psc=1) - [First Aid Beauty KP Bump Eraser Body Scrub](https://lovi.care/skincare/es/p/first-aid-beauty/kp-bump-eraser-body-scrub/for/dark-spots) — Average fit — [€25.02 at Amazon](https://www.amazon.de/dp/B08GNS58PQ?tag=lovi-care-web-product05-21&linkCode=osi&th=1&psc=1) - [First Aid Beauty Facial Radiance Pads](https://lovi.care/skincare/es/p/first-aid-beauty/facial-radiance-pads/for/sensitive-skin) — Superior fit — [€29.33 at Lookfantastic](https://www.lookfantastic.es/p/first-aid-beauty-brighten-glow-facial-radiance-pads-60-count/17659264/) - [Murad Rapid Dark Spot Correcting Serum](https://lovi.care/skincare/es/p/murad/rapid-dark-spot-correcting-serum/for/acne-prone-skin) — High fit - [Skinbetter Science AlphaRet Overnight Cream](https://lovi.care/skincare/es/p/skinbetter-science/alpharet-overnight-cream/for/dry-sensitive-skin) — High fit - [St. Ives Apricot Scrub](https://lovi.care/skincare/es/p/st-ives/apricot-scrub/for/dry-skin) — Average fit - [COSRX AHA/BHA Clarifying Treatment Toner](https://lovi.care/skincare/es/p/cosrx/aha-bha-clarifying-treatment-toner/for/oily-acne-prone-skin) — Superior fit — [€14.11 at Amazon](https://www.amazon.de/dp/B073P6BPF5?tag=lovi-care-web-product05-21&linkCode=osi&th=1&psc=1) - [Dr. Dennis Gross Alpha Beta Universal Daily Peel](https://lovi.care/skincare/es/p/dr-dennis-gross/alpha-beta-universal-daily-peel/for/acne-prone-skin) — Superior fit — [€175.00 at Amazon](https://www.amazon.de/dp/B009QZ595Q?tag=lovi-care-web-product05-21&linkCode=osi&th=1&psc=1) - [Pixi Glow Tonic](https://lovi.care/skincare/es/p/pixi/glow-tonic/for/oily-skin) — Superior fit — [€11.50 at Notino](https://www.notino.es/pixi/glow-tonico-facial-calmante-con-acido-glicolico/p-16299386/) - [Good Molecules Overnight Exfoliating Treatment](https://lovi.care/skincare/es/p/good-molecules/overnight-exfoliating-treatment/for/oily-skin) — Superior fit — [€20.99 at Amazon](https://www.amazon.de/dp/B08TMDRF1L?tag=lovi-care-web-product05-21&linkCode=osi&th=1&psc=1) - [CeraVe Skin Renewing Nightly Exfoliating Treatment](https://lovi.care/skincare/es/p/cerave/skin-renewing-nightly-exfoliating-treatment/for/acne-prone-skin) — High fit ### [Collagen peptide](https://lovi.care/skincare/es/ingredients/collagen-peptide) products - [SkinMedica TNS Advanced+ Serum](https://lovi.care/skincare/es/p/skinmedica/tns-advanced-serum/for/mature-skin) — High fit - [Hero Mighty Patch](https://lovi.care/skincare/es/p/hero/mighty-patch/for/sensitive-skin) — High fit - [The INKEY List Collagen Peptide Serum](https://lovi.care/skincare/es/p/the-inkey-list/collagen-peptide-serum/for/dry-sensitive-skin) — High fit - [Olay Regenerist Collagen Peptide 24 Serum](https://lovi.care/skincare/es/p/olay-regenerist/collagen-peptide-24-serum/for/dry-skin) — High fit - [No7 Pure Retinol 1% Night Concentrate](https://lovi.care/skincare/es/p/no7/pure-retinol-1-night-concentrate/for/combination-skin) — High fit - [No7 Protect & Perfect Intense Advanced Night Cream](https://lovi.care/skincare/es/p/no7/protect-and-perfect-intense-advanced-night-cream/for/mature-skin) — Superior fit - [Olay Regenerist Collagen Peptide 24 MAX Face Moisturizer](https://lovi.care/skincare/es/p/olay/regenerist-collagen-peptide-24-max-face-moisturizer/for/dry-skin) — High fit — [€21.78 at Amazon](https://www.amazon.de/dp/B08WX8FH85?tag=lovi-care-web-product05-21&linkCode=osi&th=1&psc=1) - [No.7 Pure Retinol 0.3% Night Concentrate](https://lovi.care/skincare/es/p/no-7/pure-retinol-0-3-night-concentrate/for/dark-spots) — High fit - [Olay Collagen Peptide 24 Eye Cream](https://lovi.care/skincare/es/p/olay/collagen-peptide-24-eye-cream/for/mature-skin) — Superior fit ## Questions and answers ### Can you use glycolic acid and collagen peptide together? Keep [glycolic acid](https://lovi.care/skincare/es/ingredients/glycolic-acid) and [collagen peptide](https://lovi.care/skincare/es/ingredients/collagen-peptide) apart because the low pH of glycolic acid may destabilize peptide bonds and reduce their bioactivity. Use them in separate steps or routines, such as applying one in the morning and the other at night. ### Which goes first, glycolic acid or collagen peptide? Keep glycolic acid and collagen peptide apart in your routine because the low pH of glycolic acid destabilizes peptides. Use them in separate steps or routines, such as applying glycolic acid in the morning and collagen peptide at night. ### Are glycolic acid and collagen peptide good for sensitive skin? Glycolic acid and collagen peptide are generally not recommended to be used together, especially for sensitive skin, because the low pH of glycolic acid can destabilize peptide bonds and reduce their effectiveness. Instead, use them in separate routines, such as applying one in the morning and the other at night. ## Research on glycolic acid and collagen peptide - [Microneedling by dermapen and glycolic acid peel for the treatment of acne scars: Comparative study](https://pubmed.ncbi.nlm.nih.gov/30548170/) Glycolic acid · Journal of Cosmetic Dermatology, 2019 -
