Navigating through the Hong Kong summer with acne-prone skin can be daunting due to the complex interplay of heat, humidity, and skin physiology. Understanding the scientific basis behind why these factors exacerbate acne will help you choose the right skincare practices. Here's a detailed look into how summer conditions affect acne-prone skin and the critical role of moisturizers.


Acne and Humid Summer Weather

The rise in temperatures during summer impacts our skin's biochemical environment, leading to increased acne breakouts:

Increased Oil Production

Higher temperatures cause an elevation in body temperature, prompting the body to sweat in an effort to cool down. Concurrently, there's an increase in the activity of sebaceous glands, which secrete sebum. Sebum, while naturally protective, can become problematic when produced in excess, as it mixes with dead skin cells and blocks pores. This blockage forms a nutrient-rich environment for Propionibacterium acnes, the bacteria primarily responsible for acne, to grow, leading to inflammation and pustule formation.

Sweat Clogging Pores

Sweating is your body's natural cooling mechanism, but it has unintended consequences for your skin. When sweat mixes with sebum and dead skin cells, it forms a viscous emulsion that can occlude pores. The occlusion prevents sebum from being secreted normally, creating an anaerobic environment conducive to bacterial growth and acne exacerbation.

Breakdown of Natural Oils

The lipid composition of sebum can change in response to high humidity and temperature. Typically, sebum contains a balance of squalene, free fatty acids, and triglycerides. Heat can induce lipid peroxidation (oxidative degradation), turning the sebum more viscous and comedogenic (pore-blocking). This altered sebum is more likely to combine with keratinocytes (skin cells) in the follicle, leading to comedones (blackheads and whiteheads).

Increased Activity

More outdoor activities mean increased exposure to dust and environmental pollutants, which can adhere to the skin's oily surface and get embedded within pores, further exacerbating skin congestion and acne flare-ups.

Makeup Use

Makeup can create a barrier over the skin that traps heat and sweat beneath it. This not only disrupts normal thermal regulation by the skin but also mixes with sebum to form a thicker occlusive layer that is hard to cleanse, promoting acne formation.



Why Should I Use a Daily Moisturizer for Acne-Prone Skin?

In the face of these challenges, using a daily moisturizer tailored for acne-prone skin becomes crucial:

Stay Hydrated

Despite the increase in oil production, your skin can still be dehydrated in summer. Dehydration in the skin triggers increased sebum production as a compensatory mechanism, worsening acne. A good moisturizer helps maintain optimal hydration levels in the stratum corneum (the outermost layer of the skin), crucial for barrier function and reducing sebum overproduction.

Maintain Healthy Skin Barrier

A compromised skin barrier allows easier penetration of irritants and bacteria, exacerbating acne. Moisturizers containing key ingredients like hyaluronic acid, glycerin, and ceramides help reinforce the skin barrier. Hyaluronic acid, for instance, acts as a humectant that binds water molecules to the skin, enhancing hydration and elasticity. Ceramides support the lipid matrix of the skin, enhancing barrier integrity and resilience against irritants.


Tips for Finding a Moisturizer for Acne-Prone Skin

Choosing the right moisturizer for acne-prone skin is vital, especially during the challenging weather conditions of summer 2024. Here’s how to identify the best moisturizer that won’t exacerbate your acne but instead will support and improve your skin’s health.

Lightweight, Oil-Free, Non-Comedogenic

The ideal moisturizer for acne-prone skin should be lightweight, oil-free, and non-comedogenic. These characteristics ensure that the product won’t weigh down your skin or leave a greasy residue that can lead to further clogged pores. Oil-free moisturizers are specifically formulated to provide hydration without adding extra oil to your already oily or acne-prone skin.


Sun protection is crucial for all skin types, but if you have acne-prone skin, choosing a moisturizer with SPF can be particularly beneficial. Sun exposure can not only increase the risk of skin cancer but can also exacerbate acne scars, making them more difficult to fade. A daily moisturizer with at least SPF 30 will help protect your skin from the sun's harmful UV rays while taking care of its moisture needs.

Ingredients for Acne-Prone Skin

Selecting a moisturizer with the right active ingredients can make a significant difference in managing acne. Here are some key ingredients to look for:

- Hyaluronic Acid: Helps retain moisture to keep your skin hydrated without clogging pores. It’s excellent for all skin types, including oily and acne-prone skin. - Niacinamide: Reduces inflammation and redness, and can improve skin barrier function, making it harder for irritants and bacteria to cause acne. - Benzoyl Peroxide: An antimicrobial agent that kills acne-causing bacteria and helps clear existing breakouts. - Tea Tree Oil: Known for its natural anti-inflammatory and antimicrobial properties, making it effective at calming redness, swelling, and inflammation. - AHA (Glycolic Acid) and BHA (Salicylic Acid): Exfoliants that help remove dead skin cells and clear pores, which can prevent breakouts. Salicylic acid is particularly effective for oily skin. - Azelaic Acid: Helps refine the skin’s surface and reduce bacteria growth, as well as diminish acne scars. - Retinol: Promotes skin renewal and may help reduce the appearance of acne scars over time. - Vitamin C: Helps to brighten the skin and may also promote collagen production, improving the skin's healing process. - Sulfur: Another ingredient that helps remove dead skin cells and excess oil, which can prevent acne flare-ups.

Incorporating these ingredients into your skin care routine can not only help hydrate your skin but also address the underlying causes of acne, leading to clearer, healthier-looking skin.

How can Each Skin Type be Acne-Prone?

Each skin type has unique physiological characteristics and responses to external and internal factors, which can predispose it to acne. Understanding the pathophysiology behind these processes is key to effective prevention and treatment.

Dry Skin

- Harsh Cleansers & Over-exfoliation: Overuse of harsh cleansers or excessive exfoliation can disrupt the skin's lipid barrier, leading to transepidermal water loss (TEWL). This dehydration signals the sebaceous glands to produce more sebum as a compensatory mechanism, which can mix with dead skin cells and debris to clog pores and promote acne. - Irritating Products: Skincare products with high concentrations of alcohol, fragrances, or other irritants can further compromise the skin barrier integrity, enhancing susceptibility to infections and inflammation, which are conducive to acne outbreaks. - Lack of Moisture: Dry skin tends to have a compromised stratum corneum (the outermost layer of the epidermis), which can lead to an accumulation of dead skin cells that block pores. Additionally, without adequate hydration, the skin's natural desquamation process (shedding of dead skin cells) is impaired, increasing the risk of comedones (blackheads and whiteheads).

Oily Skin

- Excess Oil Production: An overproduction of sebum, often driven by genetic factors or hormonal imbalances (such as elevated androgens), can lead to oily skin. The excess sebum mixes with dead skin cells in the pilosebaceous unit (a structure consisting of hair, hair follicle, and sebaceous gland), forming a plug that can become inflamed and evolve into acne. - Improper Cleansing: Inadequate or excessive cleansing disrupts the skin’s natural microbiome and pH balance. Insufficient cleansing leaves excess sebum and dirt on the skin, which clogs pores, while over-cleansing can strip away essential lipids, exacerbating sebum production as a rebound effect.

Combination Skin

- T-Zone Issues: Combination skin features an oily T-zone and dry cheeks, presenting challenges of both skin types. The T-zone’s excessive sebum production can lead to clogged pores, while the dry areas may suffer from barrier dysfunction and scaling, which can trap bacteria and sebum, leading to acne. - Improper Skincare Routine: Using products that do not address the specific needs of each facial area can lead to suboptimal care, exacerbating dryness, oiliness, and susceptibility to acne. It's crucial to apply zone-specific treatments to balance the skin's varied demands.



Other Causes of Acne-Prone Skin

Beyond hot, humid weather, several other factors contribute to the development of acne:


Androgens such as testosterone stimulate the sebaceous glands to produce more sebum. During hormonal fluctuations—like puberty, menstrual cycles, or pregnancy—increased sebum production can lead to blocked pores and subsequent acne.

Dead Skin Cells

Impaired shedding of dead skin cells can cause hyperkeratinization, where the skin cells accumulate and stick together with sebum, blocking the follicle opening and forming a comedone.


Foods with a high glycemic index cause a spike in insulin levels, which can stimulate androgen secretion, increase sebum production, and promote follicular hyperkeratinization—all contributing to acne development.


Chronic stress induces the release of cortisol and other adrenal steroids, which can stimulate the sebaceous glands and exacerbate acne.


Poor skincare hygiene can lead to an accumulation of sebum, bacteria, and dead skin cells on the skin surface, exacerbating acne conditions.


Certain medications like corticosteroids, androgens, and lithium are known to provoke or worsen acne as a side effect.


Genetic predisposition plays a significant role in the development of acne; having family members with acne increases the likelihood of developing similar conditions due to inherited tendencies in sebaceous gland activity and hormonal responses.
