Resurface+ AHA/BHA Niacinamide Exfoliating Pads

Glycolic acid is a potent alpha-hydroxy acid (AHA) derived from sugar cane and is widely used in skincare for its exfoliating and rejuvenating properties. With the smallest molecular size among AHAs, glycolic acid penetrates the skin effectively, making it a popular choice for addressing various skin concerns. It works by breaking down the bonds between dead skin cells, promoting cell turnover, and stimulating collagen production.

This ingredient is particularly effective for treating hyperpigmentation, fine lines, and uneven skin texture. Glycolic acid also has humectant properties, helping to hydrate the skin and improve overall moisture retention. Its ability to unclog pores makes it beneficial for acne-prone skin, while its exfoliating action can help reduce the appearance of acne scars.

Typical concentrations in over-the-counter products range from 5% to 10%, while professional treatments may use higher concentrations. It's important to note that glycolic acid can increase skin sensitivity to UV radiation, so sunscreen use is crucial when incorporating this ingredient into a skincare routine. Those with sensitive skin should start with lower concentrations and gradually increase usage to minimize potential irritation.

Lactic acid is an alpha-hydroxy acid (AHA) derived from milk and fermented fruits. This versatile ingredient has gained significant popularity in skincare formulations due to its gentle yet effective exfoliating properties. With a molecular size larger than glycolic acid, lactic acid penetrates the skin more slowly, making it suitable for sensitive skin types.

At concentrations between 5-10%, lactic acid effectively removes dead skin cells, unclogs pores, and stimulates cell turnover. It also has humectant properties, attracting moisture to the skin and improving hydration. Regular use of lactic acid can lead to improved skin texture, reduced appearance of fine lines, and a more even skin tone.

Lactic acid has a pH-adjusting effect, helping to maintain the skin's natural acidic environment. This supports the skin's barrier function and can aid in managing acne-prone skin. Additionally, lactic acid has been shown to stimulate ceramide production, enhancing the skin's natural moisture retention capabilities.

While generally well-tolerated, users should start with lower concentrations and gradually increase usage to minimize potential irritation. Sunscreen application is crucial when using lactic acid products, as AHAs can increase photosensitivity.

Niacinamide, also known as nicotinamide or vitamin B3, is a versatile and well-researched skincare ingredient with numerous benefits for various skin types and concerns. This water-soluble vitamin plays a crucial role in cellular energy production and repair processes within the skin.

Niacinamide is renowned for its ability to improve skin barrier function by increasing ceramide production, which helps retain moisture and protect against environmental stressors. It has been shown to regulate sebum production, making it beneficial for those with oily or acne-prone skin. The ingredient also possesses anti-inflammatory properties, helping to soothe irritated skin and reduce redness associated with conditions like rosacea.

Furthermore, niacinamide has demonstrated efficacy in improving skin tone and texture by inhibiting melanosome transfer to keratinocytes, thus reducing the appearance of hyperpigmentation and dark spots. It can also stimulate collagen production, contributing to improved skin elasticity and reduction of fine lines.

Typically used in concentrations between 2% and 5%, niacinamide is well-tolerated by most skin types and can be easily incorporated into various skincare formulations, including serums, moisturizers, and toners.

Salicylic acid is a beta-hydroxy acid (BHA) derived from willow bark, renowned for its efficacy in treating acne and various skin conditions. This oil-soluble compound penetrates pores, effectively exfoliating and unclogging them by dissolving excess sebum and dead skin cells. Its keratolytic properties promote cell turnover, leading to smoother skin texture and improved clarity.

As an anti-inflammatory agent, salicylic acid helps reduce redness and swelling associated with acne lesions. It also possesses mild antimicrobial properties, assisting in the control of acne-causing bacteria. Typically used in concentrations ranging from 0.5% to 2% in over-the-counter products, salicylic acid is suitable for oily and acne-prone skin types.

Beyond acne treatment, salicylic acid is effective in managing conditions such as seborrheic dermatitis, psoriasis, and keratosis pilaris. It can help reduce the appearance of fine lines and improve overall skin tone when used in lower concentrations. However, it may cause dryness or irritation in some individuals, particularly those with sensitive skin. Sun protection is crucial when using products containing salicylic acid, as it can increase skin sensitivity to UV radiation.
