What Does Glycolic Acid Do? Ingredients

What Does Glycolic Acid Do?

Glycolic Acid is the smallest Alpha Hydroxy Acid used in skincare, which allows it to penetrate quickly and support visible exfoliation. Regular, gentle use can help improve the look of texture, dullness and fine lines by encouraging the surface layer of skin to renew more evenly. Because it's an active exfoliant, it's best introduced gradually and always paired with daily sun protection.

Mandelic Acid vs Glycolic Acid Ingredients

Mandelic Acid vs Glycolic Acid

Both are Alpha Hydroxy Acids, but their molecule size tells a different story. Mandelic Acid's larger molecule penetrates more slowly, which tends to make it gentler and better tolerated by sensitive or acne-prone skin — while Glycolic Acid's smaller size means faster, more intense exfoliation. Neither is "better"; the right choice depends on your skin's tolerance.

How to Build a Simple Skincare Routine

A good routine doesn't need ten steps. Start with a gentle cleanser, one targeted treatment for your main concern, a moisturizer suited to your skin type, and SPF in the morning. Add new actives one at a time, giving your skin a few weeks to adjust before layering in anything else.

Understanding Hyaluronic Acid Ingredients

Understanding Hyaluronic Acid

Hyaluronic Acid occurs naturally in skin, where it helps attract and hold onto moisture. In skincare, it's typically used as Sodium Hyaluronate — a more stable, more easily absorbed form. Lower molecular weight versions can penetrate more deeply, supporting hydration below the surface rather than sitting on top of skin.

Vitamin C and Antioxidants Science

Vitamin C and Antioxidants

Vitamin C is one of the most researched antioxidants in skincare, helping to support skin against environmental stress while contributing to a brighter-looking complexion. It's often paired with Vitamin E and Ferulic Acid, a combination believed to help stabilise Vitamin C and extend its effectiveness.

How to Care for Blemish-Prone Skin Skin Concerns

How to Care for Blemish-Prone Skin

Blemish-prone skin often benefits from lightweight, non-comedogenic formulas that clarify without over-stripping. Ingredients like Salicylic Acid can help keep pores clear, while Niacinamide and Zinc support a more balanced-looking complexion. Avoid over-exfoliating, which can aggravate rather than help.
