AHA 7 Whitehead Power Liquid

Source: From product name

This product can help reduce breakouts and clogged pores because it contains the following ingredient: niacinamide. This ingredient is used for treating acne and can have a noticeable effect.

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: glycolic acid

niacinamide 2.3% - 3.5%

Irritation risk:

Concentration: Effectiveness: HIGH

Is proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production

glycolic acid 4.7% - 7.1%

Irritation risk:

Concentration: Effectiveness: MEDIUM

An alpha-hydroxy acid (AHA) that helps to remove the dead skin cells on the surface of the skin reveling a more even, smoother complexation. It is also able to stimulate collagen production with long-term use. Could help to reduce pore congestion. It can be irritating to the skin. Apply sunscreen daily if using products with glycolic acid

Anti-aging

What does the product description say?

Harnessing the powers of 7% Glycolic Acid and Apple Water (an ingredient containing natural Alpha Hydroxy Acids), the lightweight exfoliant expertly removes dead skin cells and pore-clogging impurities, whilst helping to minimise the appearance of whiteheads, fine lines and roughness.

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains glycolic acid, niacinamide.

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.

Evens skin tone

What does the product description say?

Formulated with 7% Glycolic Acid (AHA), the toner gently exfoliates skin and helps reveal a radiant, even-toned complexion.

Source: Escentual

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: glycolic acid, niacinamide

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.

Exfoliation

What does the product description say?

Formulated with 7% Glycolic Acid (AHA), the toner gently exfoliates skin and helps reveal a radiant, even-toned complexion.

Source: Escentual

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: glycolic acid.

Apply sunscreen daily if using products with glycolic acid

Moisturizing

What does the product description say?

The liquid delivers vitamins, whitening agent and natural moisturising component into cleaned pores and will gradually improve skin healthy and bring acne prone skin back to normal, vibrant skin with a smooth and refined texture. Vegan. Hypoallergenic. Dermatologist tested.

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": sodium hyaluronate, butylene glycol.

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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide, panthenol

panthenol 0.35% - 0.8%

Irritation risk:

Concentration: Effectiveness: HIGH

Helps attract water to the upper layer of the skin and can help improve skin barrier function

sodium hyaluronate 0.1% - 0.4%

Irritation risk:

Concentration: Effectiveness: HIGH

One of the best moisturizing ingredients. Attracts water into the upper layer of the skin
