Key ingredients include:

AHAs (glycolic, lactic, phytic, citric) - These chemical exfoliants have large enough molecules so as not to penetrate the skin, making them gentle surface workers, loosening dead skin cells.
BHA (salicylic acid) - This exfoliating acid has a smaller-sized molecule that can penetrate pores to help rid them of blackheads and excess sebum to decongest and diminish their appearance. 
Moth Bean Extract - A natural alternative to retinol, this boosts collagen production and stimulates cell turnover. 
Coconut Water & Aloe Leaf Juice - Full of nutrients, vitamins, and antioxidants, these both possess hydrating as well as anti-inflammatory and anti-microbial properties.
Sodium Hyaluronate - The salt form of hyaluronic acid that’s more skin-compatible than HA.  
Rosehip Oil - A regenerative and brightening oil, rosehip oil’s abundant vitamins and antioxidants make this a powerful skin tone evening ingredient. 
Tamanu Oil - With anti-inflammatory, wound-healing, and collagen-boosting properties, tamanu oil’s antioxidant- and essential fatty acid-rich make-up have made this a skin hero. 
Prickly Pear Oil - Highly hydrating, this cactus-derived oil is rich in vitamin E, essential fatty acids, amino acids, and omega 6 and 9, which help boost the skin barrier’s health and moisture retention capabilities. 
Raspberry Seed Oil - Super anti-inflammatory and moisturising, this oil’s generous antioxidant and essential fatty acid content help to combat oxidative stress and aid cell regeneration.
Rice Extract - With amino acids, vitamin E and ferulic acid, the protein in rice extract is skin-soothing and hydrating, but also a powerhouse with evening out pigmentation and brightening tone overall. 
Watermelon Extract - The vitamin C and antioxidants in this ingredient help to moisturise and exfoliate, while promoting cell regeneration as well.  
Lentil Extract - This works in conjunction with other fruit and plant extracts (like watermelon) to help moisturise skin.
Green Tea Leaf Extract - An antioxidant boss, green tea extract repairs free radical damage to skin cells while promoting healthy renewal and cell function. 

Apply a thin layer to the face and neck after cleansing and toning. Follow with moisturiser. Can be used a couple of times a week or even every night, depending on your skin’s tolerance to acids, but not with other exfoliating products.  Always wear SPF, especially the day after using the Halo serum.
