What the product description says
“Experience the power of next generation exfoliating poly hydroxy acids (PHAs) with Press & Glow; the hydrating acid toner that helps to exfoliate the surface of the complexion for noticeable everyday glow .”
Source: Lookfantastic Australia

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: gluconolactone.

GluconolactoneKey activeEffect: HighA polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals~4.7–5.7%

What the product description says
“The ground-breaking overnight serum visibly minimises fine lines and wrinkles; firming and plumping the complexion to resurface skin texture and soften the face.”
Source: Lookfantastic Australia

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains retinal, gluconolactone.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

RetinalHeroEffect: HighOne step removed from the biologically active in skin form of vitamin A. Once converted to the retinoic acid in the skin, retinal is proven to be effective against all signs of aging. It improves skin cell turnover, helps fight blemishes and clogged pores, can regulate excess oil production and even skin tone. Concentrations of 0.05% and 0.1% are shown to be effective. It can, however, be irritating~0.25–0.45%

3-o-ethyl ascorbic acidEffect: Low, below effective doseA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products~0.25–0.45%
Tetrahexyldecyl ascorbateUnder-dosedBeing a lipid soluble form of vitamin C, it is more stable than ascorbic acid, but still degrades quickly and needs to be stabilized in a formulation with another ingredient. It is claimed to penetrate skin better than pure vitamin C and have the the similar benefits, but solid studies of its effectiveness are lacking. Is likely to require a higher concentration in a product than pure vitamin C to be effective. It might be able to help reduce pore clogging.~0.25–0.45%

What the product description says
“Featuring hyaluronic acid, glycerin and vitamin E, it hydrates skin at every level to deliver a supple, even-toned, more youthful-looking complexion.”
Source: Lookfantastic Australia

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: retinal.

In addition, this product contains gluconolactone. This ingredient (ingredients) might help reduce hyperpigmentation, but the effect, if any, is likely to be small.

Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

What the product description says
“PHA gluconolactone acts as a moisture magnet to help comfort and hydrate the skin , making the surface exfoliation of the skin effortless.”
Source: Lookfantastic Australia

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: glycerin, sodium hyaluronate.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: squalane, isododecane.
