Acids make our skin healthy, bright, and hydrated. And a little sting won't hurt for better complexion, because they're named chemical exfoliators for a good reason. But skin-needs as they may be, there are certain ingredients that you shouldn't use together. When layered as one, either of the two may lose its potency or both may cause corrosion on your skin due to their strong ingredient characteristics. With this, get the deets on which skincare ingredients don't jive and why they behave so.
Check them out:
Vitamin C + Salicylic/Glycolic Acids
Dear, Klairs Freshly Juiced Vitamin Drop PHP 1150
The Ordinary Glycolic Acid 7% Toning Solution PHP 900
Cosrx Salicylic Acid Daily Gentle Cleanser PHP 490
Each of these skincare acids has a shine of their own. Glycolic Acid and Vitamin C exfoliate and reveal brighter skin. Salicylic Acid fights acne and eradicates its scars. Vitamin Cs are formulated with low levels of pH for it to be effective, so mixing it with either Glycolic or Salicylic Acid won't maximize its abilities due to the acids' high level of pH.
Vitamin C + AHA/BHA
By Wishtrend Pure Vitamin C 21.5% Advanced Serum PHP 1590
Some By Mi AHA BHA Miracle Toner PHP 850
Both of these potent ingredients have their strengths: unclogging pores, lifting blackheads and whiteheads, and radiates complexion. But as strong as they are, they mustn't be used together to avoid redness and irritation. Sensitivity and damage could take place when you layer both of these acids.
