Body exfoliation 101: AHA, BHA, scrubs & everything in between
Dr Ewoma
Overview
This video provides a comprehensive guide to body exfoliation, differentiating it from facial skincare routines. It explains why exfoliation is crucial for skin health, addressing issues like dryness, texture, keratosis pilaris (KP), ingrown hairs, and hyperpigmentation. The video details various exfoliation methods, including physical (scrubs, dry brushing) and chemical (AHAs, BHAs, PHAs), and suggests application timings (pre-shower, in-shower, post-shower). It emphasizes understanding skin type and needs to choose the right exfoliation technique and product, while also cautioning against over-exfoliation and the importance of sun protection afterward.

Chapters
- Many people neglect body care, focusing only on facial routines, leading to uneven skin appearance.
- Exfoliation is the foundational step for achieving smooth, glowing body skin.
- The body's natural skin renewal process slows with age and can be further impacted by conditions like ichthyosis vulgaris.
- Body skin has fewer oil glands than facial skin, making it prone to dryness and retaining dead skin cells longer.
- Exfoliation helps resolve common skin concerns such as keratosis pilaris (KP), ingrown hairs, razor bumps, bacne, uneven skin tone, and hyperpigmentation.
Understanding why exfoliation is necessary for the body, beyond just aesthetics, highlights its role in improving skin health and addressing specific, common skin issues.
The speaker contrasts the 'glowy, dewy' face with a 'dry, decrepit, and aged' body, illustrating the common disparity that exfoliation aims to fix.
- Physical exfoliation involves manually removing dead skin cells through methods like scrubs and dry brushing.
- Overdoing physical exfoliation can cause micro-tears and damage the skin barrier.
- Chemical exfoliation uses acids to break down the bonds between skin cells, facilitating the removal of dead skin.
- The main types of chemical exfoliants are AHAs (Alpha Hydroxy Acids), BHAs (Beta Hydroxy Acids), and PHAs (Polyhydroxy Acids).
- AHAs (e.g., glycolic, lactic acid) are good for texture and pigmentation; BHAs (e.g., salicylic acid) are best for oily, acne-prone skin and KP; PHAs (e.g., gluconolactone) are suitable for sensitive skin.
Distinguishing between physical and chemical exfoliation helps learners choose the appropriate method based on their skin's sensitivity and specific concerns, preventing potential damage from improper techniques.
Salicylic acid is highlighted as a BHA ideal for acne and KP, while gluconolactone is presented as a PHA suitable for sensitive skin.
- Exfoliation frequency depends heavily on individual skin type and resilience.
- Sensitive skin may only need exfoliation once or twice a week.
- Resilient skin might tolerate daily exfoliation, but careful product selection is still crucial.
- The sensation of 'squeaky clean' is a sign of over-exfoliation and skin distress, not cleanliness.
- The most important rule is to listen to your skin: if it feels tight, red, or angry, reduce or stop exfoliation.
This section emphasizes personalized skincare, teaching learners to adjust their exfoliation habits based on their skin's real-time feedback rather than following a rigid schedule.
The speaker warns that 'squeaky clean' skin is actually a sign of distress, urging listeners to avoid this feeling.
- Exfoliation can be incorporated into the routine before, during, or after showering; choose one or rotate.
- Dry brushing is a pre-shower physical exfoliation method that requires proper technique to avoid damaging skin.
- Body scrubs are best applied to dry skin before showering to ensure proper adhesion and effectiveness.
- Moisturizing scrubs, often oil-based, are suitable for dry skin types, while non-moisturizing scrubs focus on smoothness.
- Peeling gels, a Korean import, offer gentle physical and chemical exfoliation on dry skin and are good for sensitive types.
Learning about pre-shower options like dry brushing and scrubs allows for targeted exfoliation before cleansing, particularly beneficial for dry skin or when using products that require dry application.
The speaker advises applying scrubs to dry skin pre-shower because applying them to wet skin causes them to slip off and become ineffective.
- Allocate at least 10 minutes for showering to properly cleanse and exfoliate the entire body.
- African net sponges are highly effective, hygienic, and durable tools for in-shower exfoliation.
- Acid-infused body washes offer chemical exfoliation during the cleansing step.
- Exfoliating bars provide a concentrated form of exfoliation but should not be used simultaneously with other abrasive tools like sponges.
- Pay extra attention to dry areas like elbows, knees, and heels during in-shower exfoliation.
In-shower methods, like using an African net sponge or acid-based body wash, integrate exfoliation seamlessly into the daily cleansing routine, making it easier to maintain consistent skin health.
The African net sponge is described as a staple in African households, known for its superior hygiene and exfoliating properties compared to traditional loofahs.
- Acid toners can be applied to damp skin post-shower for continued chemical exfoliation.
- Toner pads or disposable towels can help with mess-free application of liquid exfoliants.
- Exfoliating creams, often containing ingredients like salicylic acid and urea, provide both exfoliation and moisturization.
- Urea is a highly effective ingredient for combating dry skin.
- Always follow body exfoliation with sunscreen application, as exfoliated skin is more sensitive to UV damage.
Post-shower treatments like acid toners and exfoliating creams offer a way to continue addressing skin concerns like hyperpigmentation and dryness, while the reminder about sunscreen is critical for preventing sun damage.
The CeraVe SA Smoothing Cream, containing salicylic acid and 10% urea, is recommended for its dual exfoliating and moisturizing benefits, especially for dry skin.
Key takeaways
- Body exfoliation is essential for achieving smooth, healthy skin and addressing common issues like KP, ingrown hairs, and hyperpigmentation.
- Understand the difference between physical exfoliation (manual scrubbing) and chemical exfoliation (acids like AHAs, BHAs, PHAs) to select the right method for your skin.
- Tailor your exfoliation frequency and intensity to your specific skin type and condition, always listening to your skin's signals.
- Various methods exist for exfoliating before, during, and after your shower; choose what fits your routine and preferences.
- Avoid using multiple aggressive exfoliation methods simultaneously to prevent skin damage.
- Chemical exfoliants, particularly AHAs and BHAs, can help with texture, pigmentation, and acne, while PHAs are gentler for sensitive skin.
- Always protect exfoliated skin from the sun by applying body sunscreen to prevent increased sensitivity and potential damage.
