# Potassium hydroxide and copper peptide Page: https://lovi.care/skincare/sg/ingredients/potassium-hydroxide-and-copper-peptide The Lovi Fit is the same in every country; only the stores and prices differ, and the ones here are for Singapore. Keep them apart Use them at different times of day, applying the peptide first, because high alkalinity ruins the peptide. Mixing them destroys the peptide's ability to firm and smooth your skin. You can use a gentler strength or space them out by several hours. - [All about potassium hydroxide](https://lovi.care/skincare/sg/ingredients/potassium-hydroxide) - [All about copper peptide](https://lovi.care/skincare/sg/ingredients/copper-peptide) ### [Potassium hydroxide](https://lovi.care/skincare/sg/ingredients/potassium-hydroxide) products - [Glytone Mild Gel Cleanser](https://lovi.care/skincare/sg/p/glytone/mild-gel-cleanser/for/dark-spots) — High fit — [S$38.83 at Amazon](https://www.amazon.sg/dp/B002D48QI4?tag=lovi-care-web-product0e-22&linkCode=osi&th=1&psc=1) ### [Copper peptide](https://lovi.care/skincare/sg/ingredients/copper-peptide) products - [The Ordinary Multi-Peptide + Copper Peptides 1% Serum](https://lovi.care/skincare/sg/p/the-ordinary/multi-peptide-copper-peptides-1-serum/for/mature-skin) — High fit - [Biossance Squalane + Copper Peptide Rapid Plumping Serum](https://lovi.care/skincare/sg/p/biossance/squalane-copper-peptide-rapid-plumping-serum/for/dry-skin) — Superior fit — [S$98.80 at Amazon](https://www.amazon.sg/dp/B09PLKS55F?tag=lovi-care-web-product0e-22&linkCode=osi&th=1&psc=1) - [Good Molecules Super Peptide Serum](https://lovi.care/skincare/sg/p/good-molecules/super-peptide-serum/for/mature-skin) — High fit — [S$38.42 at Amazon](https://www.amazon.sg/dp/B091MTKS35?tag=lovi-care-web-product0e-22&linkCode=osi&th=1&psc=1) - [Allies of Skin Copper Tripeptide & Ectoin Advanced Repair Serum](https://lovi.care/skincare/sg/p/allies-of-skin/copper-tripeptide-and-ectoin-advanced-repair-serum/for/oily-acne-prone-skin) — High fit - [COSRX Advanced Snail Peptide Eye Cream](https://lovi.care/skincare/sg/p/cosrx/advanced-snail-peptide-eye-cream/for/dark-spots) — High fit — [S$19.06 at YesStyle](https://www.yesstyle.com/en/cosrx-advanced-snail-peptide-eye-cream-25ml/info.html/pid.1078949384?curr=SGD&rco=SG) - [Hero Cosmetics Rescue Balm](https://lovi.care/skincare/sg/p/hero-cosmetics/rescue-balm/for/mature-skin) — High fit — [S$21.75 at Amazon](https://www.amazon.sg/dp/B0F8P947RJ?tag=lovi-care-web-product0e-22&linkCode=osi&th=1&psc=1) - [Mederma PM Intensive Overnight Scar Cream](https://lovi.care/skincare/sg/p/mederma/pm-intensive-overnight-scar-cream/for/sensitive-skin) — High fit - [Perricone MD Cold Plasma Plus+](https://lovi.care/skincare/sg/p/perricone-md/cold-plasma-plus/for/mature-skin) — Average fit - [ma:nyo Bifida Biome Complex Ampoule](https://lovi.care/skincare/sg/p/ma-nyo/bifida-biome-complex-ampoule/for/dry-skin) — Superior fit — [S$40.09 at Amazon](https://www.amazon.sg/dp/B08DTTL17D?tag=lovi-care-web-product0e-22&linkCode=osi&th=1&psc=1) - [MISSHA Time Revolution Night Repair Ampoule](https://lovi.care/skincare/sg/p/missha/time-revolution-night-repair-ampoule/for/dark-spots) — High fit - [Peach & Lily Copper Peptide Pro Firming Serum](https://lovi.care/skincare/sg/p/peach-and-lily/copper-peptide-pro-firming-serum/for/mature-skin) — High fit - [Theramid Copper Peptide](https://lovi.care/skincare/sg/p/theramid/copper-peptide/for/oily-skin) — High fit ## Questions and answers ### Can you use potassium hydroxide and copper peptide together? No, you should keep [potassium hydroxide](https://lovi.care/skincare/sg/ingredients/potassium-hydroxide) and [copper peptides](https://lovi.care/skincare/sg/ingredients/copper-peptide) apart because alkaline environments cause peptides to lose their stability and activity. ### Which goes first, potassium hydroxide or copper peptide? Keep potassium hydroxide and copper peptide apart in your routine because high alkalinity causes peptides to lose stability and activity. Use them at separate times of day. ### Are potassium hydroxide and copper peptide good for sensitive skin? Potassium hydroxide and copper peptide should be kept apart in your routine. High alkalinity can cause copper peptides to lose their stability and effectiveness. ## Research on potassium hydroxide and copper peptide - [Effects of topical copper tripeptide complex on CO2 laser-resurfaced skin](https://pubmed.ncbi.nlm.nih.gov/16847171/) Copper peptide · Archives of Facial Plastic Surgery, 2006 -
