MILD GLYCOLIC EXFOLIATING TONER
Built around Glycolic Acid at 3.5%, the smallest alpha-hydroxy acid by molecular weight, this 250 ml leave-on toner reaches the surface readily and helps loosen cell cohesion to support the appearance of smoother, more even texture. Cranberry and lingonberry fruit extracts add antioxidant polyphenols for everyday defence, in a mild, considered exfoliating step for hyperpigmentation-concerned and deeper skin tones.

- Apply two to three pumps to a cotton pad and sweep gently across clean skin in the evening.
- Begin with one to two applications per week and build up slowly as tolerated. Avoid contact with eyes and lips.
- Always layer a broad-spectrum SPF 30 or higher daily, since leave-on AHA products increase the skin's sensitivity to UV at any concentration.
Vegan eligible, with certified organic cranberry and lingonberry fruit extracts. AHA sun protection advisory: this product contains 3.5% Glycolic Acid as a leave-on alpha-hydroxy acid. The FDA cosmetic AHA labeling guidance recommends daily use of a broad-spectrum SPF 30 or higher and avoidance of unprotected sun exposure during use and for one week after discontinuation. This advisory applies at any leave-on AHA concentration, including the 3.5% here. For deeper skin tones (Fitzpatrick IV to VI), start with once-weekly application and build slowly, as glycolic acid's smaller molecular weight penetrates more readily. Patch test on the inner forearm for 24 hours before facial use. Do not use on broken, irritated, or sunburned skin. Avoid concurrent use with strong retinoid, BHA, or higher-concentration AHA products in the same routine until tolerance is established. Pregnancy and nursing: consult your dermatologist before use.
Glycolic Acid is the smallest alpha-hydroxy acid by molecular weight (76 daltons) and reaches the stratum corneum readily, helping loosen corneocyte cohesion to support the appearance of surface renewal at pH below 4.5. At 3.5% in a leave-on toner it is positioned for mild surface texture support and routine use, suitable for those building AHA tolerance, and sits within the Cosmetic Ingredient Review consumer guidance for alpha-hydroxy acids1. Cranberry and lingonberry fruit extracts contribute antioxidant anthocyanin and proanthocyanidin polyphenols for environmental defence during routine use.

A RITUAL, CONSIDERED
Each formula stands on its own and belongs to the whole. Layered with intention, morning and night, the routine becomes unmistakably yours.
A twenty four hour rhythm
THE SKIN KEEPS TIME
Skin is not the same at midnight as it is at nine in the morning. Across a single day its temperature, its acidity and the moisture it loses to the air each move on a rhythm of their own. Morning and night are not two routines. They are one, kept in time.
