Beta Hydroxy Acids - BHAs

What they are

Beta hydroxy acids (BHAs) are oil-soluble exfoliants, with salicylic acid being the most commonly used in skincare. Unlike alpha hydroxy acids (AHAs), which are water-soluble, BHAs penetrate deeper into the pores, making them ideal for oily and acne-prone skin.

Uses of BHAs in Skincare

In dermatology, BHAs are frequently used in cleansers, toners and serums to treat blackheads, whiteheads and clogged pores. Their anti-inflammatory and antibacterial properties also make BHAs effective for calming breakout-prone skin.

The benefits of BHAs include clearer, smoother skin, reduced acne and a refined appearance of pores. BHAs work by dissolving oil and dead skin cells within the pores, helping to prevent future breakouts. Regular use can lead to a more balanced complexion.

Benzoyl Peroxide

What it is

Benzoyl peroxide is a well-known skincare ingredient used to treat acne. It works by killing acne-causing bacteria, reducing inflammation and helping to clear blocked pores. You will often find it in spot treatments, face washes and leave-on gels.

How it works in skincare

Mild to moderate acne - Helps clear existing spots and prevent new breakouts.

Inflamed blemishes - Reduces redness and swelling.

Body acne - Often used in body washes for the chest, back and shoulders.

When to Be Cautious with Benzoyl Peroxide

Benzoyl peroxide can be drying and irritating, especially for sensitive skin. It may cause redness, peeling and flaking, particularly within the first several weeks of use. Its use can exacerbate dryness and eczema, and is not suitable for rosacea-prone skin. It also bleaches fabrics such as towels and pillowcases.

Safety Concerns

There has been growing concern over the presence of benzene, a known carcinogen, in some benzoyl peroxide products sold in the USA. Independent testing found that under certain conditions, particularly heat, formulations containing it might break down and release benzene. This has raised safety questions and led to calls for more regulation and testing. Some dermatologists suggest being cautious, especially with over-the-counter products stored in warm environments.

If you are considering using benzoyl peroxide, it is worth choosing reputable brands and storing products properly. For milder or sensitive skin concerns, ingredients such as Azelaic Acid might be better tolerated.

Blepharoplasty

What it is

Blepharoplasty is a surgical procedure that improves the appearance of the upper or lower eyelids, and commonly referred to as an 'upper bleph' or 'lower bleph'. Blepharoplasty is rising in popularity on social media as people share their post-procedure recoveries.

The procedure can involve removing excess skin, repositioning fat and/or tightening the surrounding muscles. The general goal is to restore a more refreshed and awake appearance, and address concerns such as hooded lids, puffiness and under-eye bags. Blepharoplasty is performed by an oculoplastic or aesthetic surgeon under local or general anaesthesia.

How it works in skin and eye-area health

By adjusting tissue and removing heaviness, blepharoplasty can smooth the contour, reduce shadowing and improve the way light reflects in the eye area. Recovery typically involves swelling, bruising and possibly temporary dryness.

Supporting the skin after blepharoplasty is important. Gentle cleansing, hydration and sun protection help preserve results. Long-term, targeted skincare to support collagen and elastin production can help maintain skin quality in the delicate eye area.

Blepharoplasty does not replace skincare but works alongside it to address structural concerns.
