Acids in Skincare Routine

From unclogging pores to fading dark spots and delivering dewy hydration, skincare acids are essential tools in your glow-up routine.
What Are Acids in Skincare?
Acids in skincare are active ingredients that perform targeted functions on the skin. Despite the scary name, many are derived from fruits, milk, or even sugars, and their role is to exfoliate, hydrate, clarify, or renew the skin.

How to Safely Add Acids to Your Skincare Routine
1. Start slow
Don’t introduce more than one acid at a time. Use 2–3x per week until your skin adjusts.
2. Know your skin type
Sensitive skin? Start with lactic acid or PHA. Oily or acne-prone? Try salicylic acid.
3. Don’t mix everything
Avoid combining vitamin C, retinol, and acids in one routine unless directed by a professional.
4. Always wear sunscreen
Acids can increase sun sensitivity; even if used at night. SPF is non-negotiable.
5. Moisturize and repair
Use barrier-supporting moisturizers to minimize irritation and dryness.
Use barrier-supporting moisturizers to minimize irritation and dryness. For example, a nourishing night cream like Yerba Mate Night Revival Cream can help calm and repair skin after exfoliation.

Myth 2: You shouldn’t use acids on sensitive skin.

Myth 3: Physical scrubs are safer.
