First of all, the acetic acid degree of roses is too high, so you can only eat them, not wipe your face. If you apply rose vinegar for a long time (even if it is diluted with water), it will still destroy the acid-base balance of facial skin and make the skin fragile and sensitive.
Secondly, the effects of toner on skin include moisturizing, softening skin, absorbing lotion or essence after opening pores, and further exfoliating. Rose vinegar (especially rose vinegar mixed with water) cannot play an equivalent role with professional toner.
Thirdly, rose vinegar is an oral beauty conditioning product, and its principle of action is to achieve the effect of whitening, beautifying or slimming by accelerating metabolism, helping digestion and lowering blood pressure. Toner is a cosmetic for external use, and its principle of action is completely different from that of oral rose vinegar, so even if they have the same effect, they should never be used interchangeably.
