For salons and private-label brands, choosing a lash lift system means looking beyond the reducing agent. Formula pH, cream texture and processing control all matter.

WHY PH MATTERS

Cysteamine hydrochloride offers an alternative to thioglycolate-based lifting chemistry. Unlike many conventional thioglycolate formulas that work under distinctly alkaline conditions, Seeyo's No.1 Softening Cream is formulated close to neutral.

Seeyo No.1 Softening Cream: pH 7.22 - near-neutral softening stage.

Seeyo No.2 Fixing Cream: pH 3.02 - acidic fixing stage.

This controlled two-step approach uses a near-neutral softening stage followed by an acidic fixing stage. The lower alkalinity of No.1 may help reduce alkaline stress compared with a strongly alkaline system, although pH alone does not prove lower skin irritation.

GENTLENESS NEEDS MORE THAN AN INGREDIENT CLAIM

Concentration, processing time, lash condition and the full formula influence the treatment experience. Both cysteamine and thioglycolate systems may cause adverse skin reactions. Follow professional instructions, avoid eye contact and follow the supplied allergy-testing guidance.

SEEYO'S PROFESSIONAL TWO-STEP SOLUTION

Seeyo's cysteamine hydrochloride system pairs No.1 Softening Cream at pH 7.22 with No.2 Fixing Cream at pH 3.02. Multiple packaging formats, custom labels and retail packaging are available for salons, academies, distributors and beauty brands.
