Fit
Who should be careful
- Daily use on normal skin
Worth noting
Small details that can change the answer
- Oil Solubility. Salicylic acid dissolves in oil, allowing it to penetrate pores.
- Normal Skin Use. Normal skin needs lower concentrations and less frequent use.
- Strength Range. OTC products range from 0.5-2% salicylic acid.
- Frequency. 1-2 times weekly is sufficient for normal skin.
Normal skin can use salicylic acid but at lower strengths and frequencies.
0.5-1% is typically sufficient for normal skin.
Always follow with moisturizer to prevent dryness.
It's a useful maintenance tool, not a necessity.
Definition
What is salicylic acid?
Salicylic acid is a beta hydroxy acid (BHA) that's oil-soluble, allowing it to penetrate pores and exfoliate from within. It's commonly used for oily and acne-prone skin but can benefit other types with appropriate use.
- Oil-soluble for pore penetration
- Exfoliates inside the pore
- Has mild anti-inflammatory properties
- Available in 0.5-2% concentrations
