Why You'll Love It

• 20% Glycolic Acid (AHA): One of the most research-backed exfoliating acids, glycolic acid works at the skin's surface to promote cell turnover, helping to fade the look of dark spots and uneven pigmentation for a visibly brighter complexion.
• Antioxidant-Rich Oil Blend: The nourishing oil base delivers antioxidant protection to help defend skin against free-radical damage and environmental stressors, keeping skin looking youthful and radiant.
• Whole-Face Use: Formulated for the entire face, this essence integrates effortlessly into your existing skincare routine — simply apply after cleansing and before moisturiser.
• Unisex Formula: Suitable for all genders and designed to work across a range of skin types seeking a brighter, more refined complexion.
• No High-Concern Chemicals: Formulated without high-concern chemical ingredients for a thoughtful approach to skincare.

How to Use

1. Cleanse your face thoroughly and pat dry.
2. Dispense a few drops of the essence onto your fingertips.
3. Gently press and smooth onto the face, avoiding the eye area.
4. Follow with your favourite moisturiser or face oil.
5. Use SPF during the day, as AHAs can increase sun sensitivity.

Frequently Asked Questions

Q: What skin types is the TRSTAY 20% Glycolic Acid Essence suitable for?

A: This brightening essence is formulated for unisex, whole-face use and is generally suitable for most skin types looking to improve radiance and skin texture. If you have sensitive skin, we recommend patch-testing first and starting with less frequent use to allow your skin to adjust to the 20% glycolic acid concentration.

Q: How often should I use a 20% glycolic acid face essence?

A: For most users, starting 2–3 times per week and gradually increasing frequency as the skin adjusts is a common approach. Always follow with a broad-spectrum SPF during daytime use, as glycolic acid (an AHA) can increase the skin's sensitivity to UV light.

Q: Can I use this glycolic acid essence with other active skincare ingredients?

A: It's generally best to avoid layering multiple high-strength actives (such as retinols or other acids) at the same time. Incorporating the TRSTAY Glycolic Acid Essence into your routine on alternate evenings and following with a good moisturiser is a popular approach. Consult a dermatologist if you have specific skincare concerns.
