An intensive exfoliating serum for twice-weekly use. Routinely 81 Sunday combines AHAs, PHAs, and succinic acid to improve the appearance of dull skin and uneven texture. Its aqueous formula promotes smoother, more luminous-looking skin. Choose this serum if you are looking for an occasional exfoliation step, rather than a daily-use product.
How to use
Apply two or three drops to a clean face twice a week, morning or night. Massage gently, wait for it to absorb, and follow with moisturizer. Do not touch the dropper to your skin.
Format
25 ml.
Frequently asked questions
Can it be used every day?
No. The brand's guideline is twice a week, after cleansing and before moisturizing. Its FAQ advises against exceeding that frequency and does not recommend it for sensitive skin.
How does it differ from Everyday 86?
Sunday contains 7% glycolic acid, 5% gluconolactone, and 2% succinic acid. Everyday uses lower concentrations. The SA acronym in this range refers to succinic acid, not salicylic acid.
