RAU Cosmetics | AHA Tonic | 200 mL

Gentle Exfoliation for a Clearer, Brighter-Looking Complexion

The RAU AHA Tonic is a lightweight, alcohol-free facial toner formulated with a blend of three alpha-hydroxy acids and white tea extract. Developed and produced in Germany, it is designed to support the skin's natural exfoliation process, refine the appearance of pores, and prepare the skin for the steps that follow in a routine.

The formula combines glycolic acid with apple, tartaric, and citric acid for gentle exfoliation that helps free clogged pores and support a more even-looking complexion. Sorbitol contributes a light hydrating quality, ensuring the toner works without stripping the skin's surface.

Free of parabens, mineral oils, silicone oils, and PEGs, the formula reflects RAU Cosmetics' straightforward approach to ingredient selection — a concise, purposeful list with no unnecessary additions.

Key Ingredients

Glycolic Acid

Glycolic acid is an alpha-hydroxy acid (AHA) derived from sugar cane and is one of the most well-studied exfoliating acids in skincare. It has a small molecular size, allowing it to work effectively at the skin's surface.

In this toner, it acts as the primary exfoliating agent, helping to loosen the bonds between dead skin cells, support a smoother-looking surface, and promote a more even-toned, refined complexion with regular use.

Malic Acid

Malic acid is a naturally occurring fruit acid, most commonly associated with apples. It is a gentler AHA than glycolic acid and is often used alongside other acids to create a more balanced exfoliating profile.

In this formula, it complements the other fruit acids with a keratolytic effect — helping to unclog pores, support cell metabolism, and contribute to a more hydrated-looking skin surface.

Tartaric Acid

Tartaric acid is a naturally derived fruit acid found in grapes and tamarinds. It helps regulate the pH of acid-based formulations and contributes mild exfoliating properties.

It is particularly noted for its use in addressing uneven skin tone and the appearance of pigmentation — including post-blemish marks and skin discolouration — where it may support a brightening and evening effect.

Camellia Sinensis Leaf Extract (White Tea)

White tea is derived from the young leaves and buds of the Camellia Sinensis plant and is particularly rich in polyphenols and antioxidants.

It contains significantly higher levels of catechins than green tea, making it a powerful antioxidant ingredient. In this toner, it helps neutralise free radicals that can accelerate skin ageing, while also contributing a light moisturising quality.

Sorbitol

Sorbitol is a naturally derived humectant that attracts moisture to the skin's surface.

In this formula, it helps offset the drying potential of the acid blend, contributing a softening and conditioning quality that supports skin comfort during and after application.

Texture

The toner has a very light, watery consistency with no perceptible viscosity. It absorbs almost immediately upon application, leaving no residue or tackiness. There is a mild, clean scent that dissipates quickly. On the skin, it feels refreshing and slightly tingly at first contact — a response consistent with the mild acid content — before settling into a smooth, balanced finish.

How To Use

1. Cleanse the face thoroughly.
2. Apply a small amount of the AHA Tonic to a cotton pad.
3. Sweep gently over the face, neck, and décolletage, avoiding the eye area.
4. Allow to absorb fully before applying serum or moisturiser.
5. Follow with an SPF in the morning, as AHAs can increase photosensitivity.

Use morning and evening as part of your daily skincare routine, or begin with evening use only and increase frequency as the skin acclimates.
