PHA 15% Serum

Q: How do I use the TIRTIR PHA 15% Serum?
A: After cleansing and toning, apply 2–3 drops to your face, avoiding the eye area. Gently pat it in until fully absorbed, then follow with your moisturizer.

Q: Can I use it every day?
A: Yes, but if you’re new to exfoliants, start with 2–3 times a week and gradually increase to daily use based on your skin’s tolerance.

Q: Is it safe for sensitive skin?
A: Absolutely! PHA and LHA are gentle exfoliants that won’t irritate the skin, and Phyto-Mucin helps to strengthen the skin barrier while keeping it hydrated.

Q: Will it dry out my skin?
A: No, unlike traditional exfoliating acids, PHA retains moisture while exfoliating, and the 1:9 oil-to-water balance helps maintain skin hydration.

Q: Can I use it if I have acne-prone skin?
A: Yes! LHA is a mild exfoliant that clears pores and reduces breakouts without stripping the skin. It’s ideal for those dealing with congestion and uneven texture.

Q: Can I use it with other active ingredients like Vitamin C or Retinol?
A: PHA is gentle enough to pair with Vitamin C, but be cautious when using it with Retinol or stronger acids. If combining, use them on alternate days or at different times (PHA in the morning, Retinol at night).

Q: Will it leave a sticky or greasy finish?
A: Not at all! The serum is lightweight and fast-absorbing, leaving your skin smooth, refreshed, and non-sticky.

Q: Can I use it in the morning?
A: Yes, but always follow up with sunscreen (SPF 30 or higher), as exfoliants can make your skin more sensitive to UV rays.

Q: How long will it take to see results?
A: You may notice smoother skin and improved hydration within a few days. For long-term texture improvement and glow, consistent use for 3–4 weeks is recommended.
